Heat not Burn in 2017 – A pretty good year!

So we’re into the last month of 2017 and the end of the year is approaching fast. Christmas is three weeks away, and it’s likely quite a few smokers will be finding an iQOS starter kit under the tree as friends and family try to nudge them in a safer direction. Well, it might be a few smokers – or it might be a lot of smokers. Because 2017 has been a big year for Heat not Burn.

A lot has changed in the reduced-harm tobacco market since January. We’ve seen new products appear, and existing ones rolled out to wider audiences. HnB has started to attract attention from health researchers and lawmakers – which isn’t always a good thing, of course, but it’s an inevitable part of getting the products on sale. So, as Christmas decorations go up and the snow comes down, let’s have a look back at what 2017 has meant for Heat not Burn.

iQOS goes global

When iQOS was first released it was only available in a few test markets, but towards the end of 2016 it began appearing more widely. The UK’s first iQOS store opened in December 2016, and there are now three in London. Last year the product was almost unheard of, but now it’s becoming much better known.

The big challenge for iQOS is the US market. Before it can go on sale it has to be licensed by the Food and Drug Administration, and in March Philip Morris submitted the paperwork to have iQOS classed as a “Modified Risk Tobacco Product”. That application hasn’t been approved yet, but hopefully it should be decided next year. If the FDA approve it – and it’s hard to see how they can refuse – expect iQOS to be a big hit among US smokers.

Meanwhile, the statistics coming out of Japan show just how much potential iQOS has. PMI say they can’t keep up with demand, and every new batch they deliver sells out right away. iQOS really seems to have made an impression – and cigarette sales in Japan fell by an astonishing 11% in the first six months of this year, as smokers moved to HnB.

The growth of Glo

So far iQOS doesn’t have any serious rivals as a mainstream HnB product, but that’s likely to change soon. BAT’s competing Glo was launched in Japan last year; now the market testing has been expanded to South Korea, and next year we can expect it to start hitting other countries. The UK is a likely candidate, thanks to a generally positive attitude to reduced-risk products; BAT will also want to build a presence before iQOS becomes too firmly established as the market leader.

Glo is also the product we have most hands-on experience with at Heat not Burn UK – we did the first UK review of the product a few months ago, following a sneak preview back in February when Dick Puddlecote managed to get his hands on one. That experience was pretty convincing – Glo has a lot of potential, and we think smokers are going to like it when it hits the UK shelves.

Heat not Burn UK visits PMI

In April we were offered the chance to send someone to PMI’s research facility at The Cube in Neuchatel, Switzerland, to see what progress is being made on HnB. This gave us a chance to look at the latest science on the safety of iQOS, which is very encouraging, as well as seeing how HEETs are made in the Neuchatel factory.

What really encouraged us is that PMI aren’t just pinning all their hopes on a single product. They know that electronic devices like iQOS (or e-cigarettes) don’t work for everyone – they’re not a lot of use for people who spend long periods working outdoors or at sea, for example – so they’re working on four separate non-cigarette devices. These include a charcoal-heated cigarette and a device that creates nicotine vapour through a chemical reaction, as well as iQOS and the Mesh e-cigarette.

Lil joins the race

South Korea is a popular test market for HnB products, with iQOS and Glo both going on sale there early in their careers. Now the country’s own industries are waking up to the possibilities. Korean Tobacco & Ginseng have developed their own device, the Lil, which also heats tobacco sticks to create a vapour.

Lil is on limited release in South Korea just now, but should be rolled out across the country quite soon. The question is whether KT&G plan to market it globally. So far they haven’t announced any plans, but H&B isn’t a crowded market right now. This would be a huge opportunity for them to build a global presence.

We’ve contacted KT&G to ask if we can have a Lil for review, but haven’t heard back from them yet. Hopefully we’ll have some news on that soon, because it’s an interesting-looking device and we think it deserves a wide audience.

Looking forward

So this has been an exciting year for Heat not Burn; the technology is making its way into the mainstream, hundreds of millions of people around the world are able to buy the products, and that number is set to grow fast in 2018. If what we’ve seen from Japan is any guide, there’s a possibility that HnB could overtake e-cigarettes as the favourite alternative to smoking within a few years.

In any case, 2017 isn’t quite over yet. There are still a few weeks to go before New Year, and the team at Heat not Burn UK won’t be taking that time off. There will be a video review for the Vapour 2 Pro we’ve been testing for the last month, and we also have a new toy to play with – the PAX 3. This is the latest upgrade of the PAX 2, the most respected loose-leaf vaporiser on the market, and there’s one sitting on the table in HnB UK’s secret headquarters. That will be getting unboxed soon, and tested over the next couple of weeks, so drop in to see what we think of it!

Heat not Burn “as bad as smoking” says study – but what’s the truth?

And so it begins. A new paper presented to the American Heart Association claims that Heat not Burn products harm blood vessel function in the same way as smoking. No doubt there are a dozen other studies underway right now that will soon produce papers linking HnB to heart attacks, lung disease and various cancers. Carefully tailored press releases, all including some form of the phrase “as bad as smoking”, will be leaked to sympathetic journalists. Public health activists don’t even need to go looking for friendly hacks; they can just get in touch with the ones who wrote negative articles about e-cigarettes.

If I sound cynical about the new paper, it’s because I am. I switched from smoking to vaping five years ago, just in time to see the tobacco control industry gearing up its campaign against e-cigs. I have to confess that, at the time, I watched it unfold with total incredulity. Here was a product that got smokers to stop smoking, but the activists and scientists who’re always demanding new action to stop smokers from smoking were opposed to it! What the hell was going on?

Well, five years later, I know what’s going on. The tobacco control industry is, in big-picture terms, split between two main factions – and neither of them is really interested in helping smokers to quit. One faction is motivated by a blind, unreasoning hatred of the tobacco companies; if Philip Morris invented a cure for cancer tomorrow, this group would try to have it banned.

The other faction is no fan of the tobacco companies either, but it has different priorities. Its goal isn’t to stop smokers from smoking; it’s to campaign to stop smokers from smoking. Obviously, if all the smokers become vapers or Heat not Burn users, there won’t be any smoking to campaign against – and that means they’ll have to find new jobs, which might involve some actual hard work rather than just being handed taxpayers’ money to complain about things.

Tinfoil hat time?

Claiming that public health campaigners are more worried about their jobs than public health sounds a bit paranoid, but what’s happening in the UK right now tends to back it up. Local councils who’re trying to save money are starting to take a good look at the stop smoking services they fund – and it appears that some of them don’t like what they see. Several services, including Smokefree South West, have had their council funding stopped, and for nanny state groups that’s usually a death blow. Nobody actually wants to give them money, so if the tax tap is turned off that’s the end of them. Smokefree Southwest announced its closure within 24 hours of being defunded.

The reason councils are starting to defund anti-smoking groups is that it’s obvious they aren’t doing anything. Most councillors aren’t daft; they see smokers switching to e-cigs by the thousand, and the UK’s smoking rate falling faster than ever before. Then they see so-called “public health” groups demanding that e-cigs are taxed, restricted and banned out of existence. Finally it occurs to them that not only are these groups not doing anything to reduce smoking; they’re actively campaigning against products that are. So they pull the plug, and another dozen tobacco controllers are forced to get a proper job.

And all this is happening because of e-cigs. Just imagine what’s going to happen when HnB goes mainstream. Personally, I wouldn’t be surprised if a decade from now the UK’s smoking rate has fallen from its current 16% to around 5%. If that happens a lot more tobacco control funding is going to evaporate, which is why all the usual suspects are already moving to condemn HnB.

What does the science say?

Anyway, back to the paper. What exactly is it saying, and should we take it seriously? The short answer is “Not much and no.” That isn’t very informative, though, so let’s look at it in slightly more detail.

The paper was written by the tobacco research department at the University of California, San Francisco. If you follow the vaping debate that’s probably ringing alarm bells already, because who runs UCSF’s tobacco research department? Yep, it’s Stanton Glantz, the failed aircraft engineer who’s managed to get a job as a professor of medicine despite never having studied medicine in his life. The reality is that Glantz is an activist, not an academic, and this department is shaped in his image: Before they even start doing any research, they know exactly what results they plan to get.

What they wanted to find here was evidence that HnB is just as bad for you as smoking. Now, this is obviously a ridiculous idea. Probably the most harmful single ingredient in cigarette smoke is carbon monoxide, which is produced by combustion, and HnB doesn’t involve combustion.

What they actually mean is that one specific effect of HnB is the same as an effect of smoking. That is obviously not the same thing as saying that using HnB is as bad for you as smoking is. In this case they’re talking about something that isn’t really bad for you at all.

The paper claims that using a HnB product – specifically, iQOS – has the same effect on “Flow-Mediated Dilation”, a way of measuring the efficiency of blood vessels, as smoking a cigarette. In general terms this is true; it’s likely (not certain, but we’ll come back to that) that iQOS will cause a similar short-term effect on blood vessels to a cigarette. Where it all comes unstuck is that the authors go on to say that HnB “does not necessarily avoid the adverse cardiovascular effects of smoking cigarettes”. That statement is a massive problem.

Smoking cigarettes is really bad for your heart. Smoking cigarettes also causes short-term stiffness in your arteries every time you light up and take a puff. But these two facts are not connected. It isn’t the short-term stiffness that makes cigarettes bad for your heart; it’s the couple of hundred daily doses of carbon monoxide, which causes long-term stiffness and the build-up of arterial plaque. Many other things also cause short-term stiffness – caffeine, watching scary movies and exercise are among them. It doesn’t matter, though, because it only lasts a few minutes. Smoking is dangerous because it makes your arteries stiffer all the time, plus promote the build-up of plaque which slowly blocks them. iQOS, being free of carbon monoxide, doesn’t do this.

So what’s really going on with this paper? Leading e-cig expert and cardiologist Dr Konstantinos Farsalinos has the answer, as already reported on this site. According to the UCSF paper, the iQOS delivered 4.5 times as much nicotine to the test subjects (who, it should be pointed out, weren’t people – they were mice) as a cigarette did. As nicotine is known to cause temporary stiffening, that would certainly explain the effect. It would also suggest that it’s nothing to worry about. After all, licensed nicotine products like patches and gum cause an identical effect, and they’re sold over the counter and approved for long-term use.

If we take its data at face value, this paper shows that HnB has the same effect on blood vessels as a nicotine patch, which is regarded as very safe – in other words, there’s nothing to worry about. In fact, what the data show is that the researchers have made a very serious mistake somewhere. According to them, iQOS delivers about 350% more nicotine than a cigarette does – but three independent studies all agree that it delivers about 30% less nicotine. As Dr Farsalinos points out, it is impossible for iQOS to deliver that much nicotine. Therefore the UCSF team have screwed up somewhere, and if they’re working on terminally flawed data, that the whole paper can safely be ignored.

Unfortunately, while this one might be (it doesn’t seem to have gained much traction outside crank medical websites), as HnB becomes more popular we can expect to see more “research” being done and negative stories starting to appear in the press. It’s likely that all the smear stories that have been aimed at e-cigs will be recycled to attack HnB too. If you doubt that, consider this: Just two months ago, a paper from Sweden claimed that e-cigs have the same effect on arterial stiffness as smoking does. Sound familiar?

Heat not Burn is going to get exactly the same treatment as vaping did; I guarantee it. In fact, if anything it will be worse, because the leading HnB products actually are made by the dreaded tobacco companies. Vapers couldn’t really believe what was happening at first, and lost a lot of ground to bad science and scaremongering media before advocates started fighting back. If you’re a fan of HnB, don’t make the same mistakes; start pushing back now.

Will heat not Burn make Britain smoke free?

Ever since the first Heat not Burn devices appeared, they’ve been controversial. Most of that controversy has come from politicians and the public health industry, who seem to have hated the technology right from the beginning. If you’re a vaper their complaints will be pretty familiar; HnB users haven’t really quit, they’re still addicted to nicotine, it’s just a different kind of cigarette, it’s all a Big Tobacco plot to get children hooked… you know the sort of thing. It’s all hyped up, it’s all alarmist – and it’s all untrue.

What is true? It’s true that Heat not Burn has the potential to make smoking go away. Public health say they want this to happen, but over the past few years they’ve been very hostile to any new alternatives to smoking. The cynical might think they’re more worried about protecting their jobs than helping smokers find safer alternatives.

This might explain why all the targets set by the traditional anti-smoking lobby are slightly unambitious. Currently the British government’s tobacco control plan – largely written by taxpayer-funded activists like ASH – aims to create a “smoke free generation” by reducing the smoking rate to 5% (it’s currently around 16%). Obviously a 5% smoking rate isn’t “smoke free” in any way that resembles reality, because 5% of the UK population is actually quite a lot of people, but that’s their target. According to the trend in smoking rates over the last few years, that target should be achieved around 2040.

Now that figure is being challenged from an unexpected source. A couple of weeks ago Philip Morris released a report produced for them by Frontier Economics, an analysis consultant. Frontier have looked at the data on smoking rates in the UK, examined the current trends and what’s driving them, and come to an interesting conclusion.

The government might think that they can achieve their 5% target by 2040, but Frontier and PMI are saying that, in fact, they could get there much sooner – by 2029, just twelve years from now. It might seem surprising to hear a tobacco company advocating a faster decline in smoking, but in fact PMI have been saying this for a while now. When I visited their research centre at the Cube back in April they were very open about the fact that they plan to move away from cigarettes as fast as possible, and that the future is in alternative products.

What about vaping?

The problem is that, right now, the most common alternative product in the UK is e-cigarettes – and it looks like they might be running out of steam. The number of vapers in Britain is still rising, and an ever-increasing percentage of them have switched away from cigarettes completely (just under half of UK vapers also smoke, down from 70% two years ago), but growth is slowing down. In 2014, 800,000 British smokers started vaping, but it’s likely that by the end of 2017 the year’s total will be just 100,000. The most likely reason for this fall is that smokers have been scared off by false claims about health risks.

Now PMI say that it’s possible to reach the “Smokefree” target eleven years early – but only if the number of smokers switching to safer alternatives starts to accelerate again, back to where it was in 2014. The question is, what alternative should they switch to?

E-cigarettes are still a popular option – according to Public Health England they’re now the UK’s top choice among smokers who want to quit. It’s possible that, if people like ASH stop talking nonsense about them, the number of smokers switching to them every year could rise again. On the other hand, it’s also possible they could be overtaken by Heat not Burn. In fact I think that’s very likely.

When it comes to quitting smoking, e-cigs have been a game changer. The number of smokers in Britain is falling faster than it ever has before, even though fewer people are buying nicotine gum or using NHS quit services. They’re not ideal for everyone, though. Some smokers find them too complicated; others just want something that tastes like their favourite cigarette.

Is Heat not Burn the future?

I think a lot of smokers who aren’t interested in e-cigs are going to be very interested in HnB, for a couple of reasons. Firstly, a device like iQOS isn’t as simple as a cigarette – what is? – but it’s a lot less complicated than a high-end e-cig. Secondly, HnB can recreate the taste of cigarette smoke almost perfectly and that’s important to a lot of people. Many vapers love the array of new flavours they can use, but there are also plenty smokers who just want something that tastes like the smoke they’re used to. E-cigs are never going to recreate that flavour – they just don’t work that way – but PMI have spent a lot of money making sure iQOS tastes as much like a Marlboro as possible, and it’s paid off.

If you want to see how well it’s paid off, just look at Japan. iQOS launched there three years ago, and as of last month it’s taken 13.3% of the country’s nicotine market. It’s already broken even, paying for the enormous cost of developing it, and it isn’t even on sale in most countries yet. E-cigs have been growing fast, but not that fast.

It doesn’t stop with iQOS, either. As well as its direct competitors, like Glo and the new Lil from KT&G, there are more products due on the market soon. A couple of paragraphs back I asked what’s as simple as a cigarette. Well, PMI’s next product is. Using the same concept as RJ Reynold’s Revo, but apparently working much better, these are exactly as easy to use a cigarette. Just take it out the pack, light the end – which contains a charcoal heating pellet – then, when you’re finished it, stub it out in an ashtray. If it works as well as PMI are hoping, this could be even bigger than iQOS.

There’s a lot going on in the world of HnB right now, with new products appearing and existing ones being rolled out into new markets. There’s also a lot of opposition from the usual suspects in tobacco control, and that has the potential to put smokers off trying HnB for themselves. If we’re lucky, however, smoking could more or less disappear from the UK before 2030, and it won’t be plain packs or nagging health campaigns that do it; it will be e-cigs and heated tobacco products.

Review – Vapour 2 Pro Series 7

So far, when it comes to reviewing Heat not Burn products, our focus has been on iQOS and Glo. There are many reasons for that, including the fact that they’re gaining popularity very fast and they’re likely to be the HnB devices you see in every corner shop a couple of years from now. The main reason, however, is simple – we reviewed them because we could get our hands on them.

There are other options though, and some of them have been around for quite a long time. Probably the oldest class of HnB devices is tobacco vaporisers. These are also known as loose leaf or dry herb vaporisers, because they’re most often used with dry herbs. Hmm, what kind of herbs? Oregano? Parsley? Probably not, so we won’t go into that here. However, they do work with tobacco, using the same principles as any other HnB product – they apply heat to tobacco, to create a vapour infused with nicotine and flavour compounds while avoiding the toxic carbon monoxide and tar.

The gold standard in loose leaf vaporisers for the last couple of years has been the PAX 2. As well as being extremely popular among the herb fraternity, this also has a reputation for working well with loose leaf tobacco. The problem is that it’s very expensive – in the UK it usually sells for just under £200. That left us wondering if there were any more affordable options. After some searching we came up with the Vapour 2 Pro Series 7. This is still a high-end vapouriser, but at around £120 it’s significantly cheaper than the PAX 2. It’s also an interesting gadget for a few other reasons, so we were quite keen to have a look at it. Here’s what we think.

The review

The Series 7 and accessories

The Series 7 comes in a nice sturdy box with an outer sleeve. Inside, the top tray holds the vaporiser itself; underneath is another tray that contains a replacement atomiser, charging cable, cleaning kit and spare foil disks, and a clear, easy to use instruction leaflet. Although it was packaged separately, and not in the actual box, a Vapour 2-branded UK plug USB adapter came with it.

Before looking at the device in more detail, let’s look at that replacement atomiser. The Series 7 will take three different atomisers, two of which are supplied with it. One is a loose leaf model, and the other is an e-cigarette tank. The third is for wax concentrates, but you have to buy that one separately.

The actual device is a slim gadget a bit over four inches long, with a flattened oval cross-section. It’s pretty simple; there’s a single button on the front, with an LED surround and three more LEDs below it. Another LED ring is sandwiched between the alloy body and the chromed base. On the base itself is the charging port. Apart from that there are two air slots on the sides, and four grooves running the length of the body that improve the grip. The whole thing is surprisingly light, but feels solid and well put together. The button seems to be chromed plastic but the base is steel.

Most of the device is taken up by the battery, and all the action happens at the top. This end of it is simply an open chamber with electrical contacts at the bottom; all you have to do is drop the atomiser you want into this chamber, and a magnet on its base will lock it in. Each atomiser is topped by a black plastic mouthpiece; both mouthpieces we got look the same on the outside, but they’re not interchangeable.

Atomisers drop in here

As this is an HnB site, we’re mostly going to look at the loose leaf atomiser. I did try the e-cig one, though, and it worked pretty well. It wicks a bit slowly to keep up with high-VG liquids, and it’s never going to be a cloud beast, but with a PG-heavy juice this would be ideal to slip in your pocket when you go out. It never seems to leak and the 2ml tank is enough to keep you going for a few hours.

Trying it out

Anyway, back to the loose leaf atomiser. This is a simple enough gadget. If you twist the mouthpiece anti-clockwise it comes off, revealing a cylindrical heating chamber with a perforated foil disk at the bottom – this seems to be there to stop bits of tobacco getting into the air channel that runs through the base. All you need to do then is load the chamber with tobacco, making sure not to fill it above the white ceramic ring near the top. Don’t pack it too tightly, either; otherwise you won’t get any airflow. Then just put the mouthpiece back on and you’re ready to go.

The device can obviously tell which atomiser is fitted, because it switches into different modes depending on what’s sitting on top. The e-cig is a simple push-to-fire system, but the loose leaf mode is different. Press and hold the button for a few seconds until the LED ring around the base lights up red; then just wait for it to warm up. After about 20 seconds the ring will turn amber; in another ten it goes green, and you’re ready to start puffing. It will stay at running temperature for 90 seconds, then automatically shut down; the LED ring will start flashing five seconds before the power goes off.

This is where it gets complicated. I have to say, the first few times I tried it I was more than a bit underwhelmed by the amount of vapour it produced. It tasted fine – very like a cigarette. It seemed to be delivering enough nicotine, too. There just wasn’t very much of it. I’m no cloud chaser, but I’m still used to the vapour production of a modern e-cig, so the little wisps from the Series 7 were a bit of a disappointment.

In fact it was so disappointing that I tried out a suggestion that had been made as a joke: Add some VG to the tobacco. I put some tobacco in a jar, added enough PG to moisten it, and left it overnight. That did a lot for the vapour, but changed the taste quite radically – after all, VG is used as a natural sweetener in a lot of foods.

Heat not Burn UK isn’t a site that gives up easily, though, so I persevered – and finally I cracked it. The secret is the amount of tobacco you put in: Too much, even if it’s loose enough to let the air flow freely, and you don’t get much vapour. Open your baccy pouch, take out enough to loosely fill the chamber – then put about half of it back. I’m guessing that using too much tobacco stops the chamber getting hot enough to create a lot of vapour, but when it’s properly loaded the results are much more impressive.

Battery life turned out to be fairly good. It won’t last a whole day, but it’s easy to charge. The charging port is interesting – it’s magnetic, instead of the usual micro USB. This makes it more robust, and it’s also very quick and easy to connect. If you’re using it at home it’s simple to top up the charge between vaping sessions. Another interesting – but also weird – touch is that there’s a small blue LED mounted on the end of the charger. I have no idea why.



This was the first loose leaf vaporiser I’d tried, and after the initial process of getting to know how it worked I was quite pleased with it. If you’re looking for huge clouds of vapour the Series 7 probably isn’t for you, but if you just want something to replace your cigarettes that could be a different story. It isn’t quite as close to the experience of smoking as iQOS or Glo, but it does have the advantage of flexibility. The mainstream HnB devices have a pretty limited range of flavours right now, and while that will probably grow over time, I doubt it’s ever going to be huge. With the Series 7, however, you have a lot more options. I tried it with  standard rolling tobacco and a shredded Cohiba cigar, but you also have the full range of pipe tobaccos available, and I think it could work very well with some of those.

Learning to pack the loose leaf atomiser is a bit fiddly, but once you’ve cracked it the Vapour 2 Pro is a solid performer. The e-cig mode is also a nice touch, and you can switch between e-liquid and tobacco in seconds. Overall this is a very nice system; it seems to be well made, and with a bit of practice it delivers a satisfying tobacco vape. If you’re interested in a loose leaf vaporiser and don’t want to shell out for a PAX 2 (or want the ability to use e-liquid too) you won’t go far wrong with the Vapour 2 Pro Series 7.

More Heat not Burn science – Glo has been tested!

Back in April we looked at the latest research on the safety of iQOS compared to traditional cigarettes, and it looked very encouraging for heat not burn devices. Studies carried out for PMI by independent labs found that the vapour from an iQOS had much lower levels of toxic chemicals than cigarette smoke – in most cases, 90% or 95% lower. That’s impressive, especially considering that the tests looked at a much larger range of chemicals than any research done by public health groups.

The down side to this research was that it only looked at iQOS. Yes, that particular product is much safer than smoking, but does it apply to HnB in general? Realistically it’s going to be a while before we know that for sure, but this week some more results were released, this time by British American Tobacco. We recently did the first full UK review of BAT’s new Glo, their entry in the HnB market; now there’s some science to go with our impressions of this device.

Real science?

Although research done by the tobacco industry in the past has had a bad reputation, things have moved on a long way since the 1960s. Companies like BAT know that anything they publish is going to be scrutinised in minute detail by activist scientists looking for the slightest hint of foul play, so they don’t take any chances. These days they’re scrupulous about following good research procedures and releasing details of their methods, so the research can be studied and replicated. How well are they doing at that? Well, all the criticism of PMI’s research on iQOS has been about where the money comes from; nobody has said a word against the science. That probably tells us all we need to know.

BAT seem to have been just as careful with their own research, which makes the results worth looking at. For a start, they didn’t just bodge up some shonky equipment, like one university did recently when they used syringes to collect vapour from e-cigs. Instead, they studied how people actually use Glo then programmed a robot smoking device to replicate that. Then they tested Glo, collecting the vapour for comparison with a range of other products.

In total seven products were tested:

  • Glo
  • Three conventional cigarettes, including the standard 3R4F reference cigarette used in most smoking research.
  • “Another THP (tobacco-heating product)”, almost certainly an iQOS.
  • “A hybrid product”, BAT’s iFuse
  • An e-cigarette.

This is a good selection of products, covering all the main categories on the market right now. BAT also tested for a wide range of chemicals. They used the Health Canada testing method to collect vapour, because it’s one of the most thorough methods in use, combined with their own list of chemicals. The FDA test for 28 different toxins in cigarette smoke; the International Agency for Research on Cancer only measure fifteen. BAT’s list has 44 substances in it – not quite as extensive as the 58 that PMI look for, but still much more impressive than what most health researchers are doing.

Checking the chemistry

What’s really impressive is the results of all this testing. Unsurprisingly, most of the vapour from Glo consisted of water vapour and glycerine, which is added to increase the vapour output. That’s interesting, because when we looked at the innards of a NeoStik the tobacco in it looked much less processed than the contents of a Heet. Obviously, even though what the Glo is heating looks like normal cigarette tobacco, BAT have added a considerable amount of glycerine to it somehow. That doesn’t cause any worries, though; glycerine is perfectly safe to inhale.

The nicotine content of the vapour was about 62% of that found in cigarette smoke. This makes sense; using the Glo, it felt similar to a light cigarette, while the 3R4F cigarette is a full-strength blend. In any case, this sort of nicotine dose is close enough to a cigarette that it’s an effective replacement.

Moving on to the less welcome substances, the tests showed sharp reductions in all of them. The lowest reductions were for mercury, at 57.1%, followed by ammonia at 64.3%. Neither of these chemicals are at high enough levels in cigarette smoke to be much of a worry anyway, but any reduction is welcome. For the other 41 chemicals tested, 39 had a reduction of at least 80% and 36 saw levels reduced by 90% or more. Almost half had at least a 99% reduction. The total reduction in toxins was around 90%.

Does this mean it’s safe?

It’s worth pointing out that a 90% reduction in toxins is impressive, but it doesn’t tell the whole story. For example, the single most harmful chemical in cigarette smoke is carbon monoxide, and smoke contains a lot of it. The level in Glo vapour was 98.6% lower. Benzene is another major problem for smokers; Glo reduces the leve by 99.3%. Hydrogen cyanide – 98.8% lower. What this means is that while switching from cigarettes to Glo cuts total toxins by 90%, it almost certainly cuts the health risk by a lot more.

More good news from the study is that iQOS and the e-cigarette gave roughly similar results to Glo (although many of the toxins aren’t found in e-cig vapour at all).

Between this new research and what PMI have already released about iQOS, it seems obvious that HnB is much safer than smoking, and probably about the same as vaping an e-cigarette. A reduction in risk of at least 95% seems likely to be about right. Does this mean that switching to Glo cuts your risk of premature death by 95%? No – it almost certainly cuts it by a lot more than that. Jumping from a ground-floor window is about 95% less risky than jumping from a fourth-floor one, but the risk that’s left doesn’t mean your chance of dying drops from 50% to “only” 2.5%. It means that, if you’re really unlucky, you might twist your ankle.

If you need a final vote of confidence in BAT’s new research it’s just been published in a peer-reviewed medical journal, Regulatory Toxicology and Pharmacology. Peer review means a panel of experts have examined and decided that the experiments were good science and the data has been properly interpreted. Of course some extremists will refuse to accept it simply because it was funded by BAT, but open-minded people like our readers can find it here.

Beyond iQOS and Glo – What other options are there?

Over the last few months this site has been focusing quite heavily on iQOS and its BAT rival, Glo. We make no apologies for that; they’re both excellent products, they’re either on the market or will be soon, and we think millions of smokers are going to enjoy them as a healthier alternative to traditional cigarettes. If you’re interested in switching to heat not burn, iQOS is probably your best option in most countries. Glo isn’t widely available yet, but we can expect BAT to start rolling it out beyond its Japanese test market as soon as they’ve ramped up production of NeoStiks.

We’re fair-minded people, though, and we don’t want to give Philip Morris and British American all the publicity, so this week we’re going to look at a few less well known products that are either available, have come and gone or are planned for the near future. Some of them are promising; some of them are flops. But we think they deserve some attention anyway.


V2 Pro

The V2 Pro was originally released about three years ago, and although it’s never really taken off it’s survived and gone through several upgrades. The standard models use a proprietary magnetic connector to let you switch between different atomisers, which included a conventional e-cigarette tank and a loose leaf version. That has some power limits, though, so V2 have diversified their range and produced a dedicated tobacco vaporiser.

V2’s Pro Series 7 is a chunky but compact device about the size of a highlighter pen. Its oval body has a built-in battery, charged through a magnetic port, and at the other end is a removable mouthpiece. Pull that off and you’ll find a generously sized vaporising chamber that can be filled with your favourite loose leaf ingredient – we’d suggest a good pipe tobacco.

We haven’t managed to test the Series 7 ourselves (although we will if anybody wants to send us one) but it looks very promising. This could give the popular Pax 2 a run for its money in the loose leaf category.

iSmoke One Hitter

Similar in concept to the original V2 Pro, this is another pen-style vaping device that looks a bit like an eGo or Evod – but, instead of a clearomiser for e-liquid, it has a loose leaf atomiser that will hold almost a gram of tobacco.

If you’re looking for an affordable intro to HnB, this might be ideal. It only seems to be on sale in the USA right now, but the recommended price is a tempting $19.99. With traditional loose leaf devices averaging about $150 for a good one I’d be tempted to try this myself. It’s compact, looks simple and seems to do a pretty good job of turning tobacco into vapour without burning it.

Pax 3

We’ve talked about the Pax 2 before. It’s one of the most highly regarded loose leaf vaporisers out there, and has built a solid reputation for good build quality, excellent performance and durability(even if the $200 price tag is a bit steep). Now its makers have gone one better, and introduced the unimaginatively named Pax 3.

If the older model is too expensive for you, look away now; the Pax 3 costs an eye-watering $275. It delivers a lot for your money, though. As well as the high quality we’ve come to expect from this company it has some nice tweaks and a couple of completely new features.

The Pax 3 is mainly designed for “dry herbs”, but also works very well with hand-rolling or pipe tobacco. It has a capacious chamber that will hold enough tobacco to give you a satisfying vape session, plus the option to load a smaller amount and use a spacer to keep it well packed.

One issue many people had with the Pax 2 was the mouthpiece overheating, but a new design in the 3 fixes that. It keeps the bottom-mounted heating chamber, which also means the vapour has a chance to cool slightly before reaching your mouth.

Finally, the Pax 3 can now be controlled and adjusted through an iOS or Android app. Which lets you adjust the heating temperature to taste. This makes for a very versatile device, and if you don’t mind the price tag it’s hard to think of a better loose leaf vapouriser.

Ploom Model2

The original Ploom was developed by the people who now make the Pax series, but the technology and name were bought by JTO a couple of years ago and updated into the PloomTech. Some of the original Model 2 kits are still kicking around, though, and if you can get one they’re definitely worth a try.

Ploom 2 is similar to iQOS and Glo in that it uses proprietary tobacco inserts – but these are very different to the cigarette-like Heets or NeoStiks. Instead they’re tiny, bullet-shaped capsules made of heavy foil, which drop into the heating chamber and get punctured by the mouthpiece. A heating coil vaporises the tobacco, and you get a mouthful of aromatic fumes.

Overall this works pretty well – not as well as iQOS, but it’s less like a cigarette if that bothers you. The capsules come in a decent variety of flavours, too.


So will any of these devices take the heat not burn market by storm? If I’m honest here, probably not. None of them have the marketing clout behind them that Glo and iQOS do, and none of them are really as good either. The loose leaf devices are tarred with the illegal drugs brush – they work fine with tobacco, but tobacco isn’t what anyone sees you using one is going to think of. They can also be very expensive to buy. Of course you’ll then save on the cost of tobacco, but it’s still a lot of money to hand over for a small gadget.

It’s always worth keeping an eye on the market, though. This is a fast-moving technology, and with iQOS proving popular everywhere it’s available (and Glo doing very well in Japan, apparently) a lot of companies are going to try to move in. Most of them will fail, but there’s always the chance of some very nice products appearing. We’ll certainly be looking out for anything interesting!

Heat not Burn UK exclusive – BAT Glo review

If there’s a bad thing about heat not burn it’s that the latest products aren’t widely available yet. That’s slowly changing as they roll out across new markets, but when we reviewed iQOS last summer it was only on sale in a handful of countries – and the UK wasn’t one of them. Obviously we were very excited about doing one of the first UK reviews of a product that’s turned out to be a real game changer.

Well, now we’ve done it again. British American Tobacco’s new Glo is only available in Japan and South Korea right now, but Heat Not Burn UK have managed to get our hands on one and, as promised, it’s now been through a full review.

You might remember that we did a preliminary review of the Glo a while ago. That was interesting, but it did have some limits. The main ones were that it was a borrowed device, there weren’t many sticks with it, and the person who actually had it was at the other end of a Skype conversation and half way down a bottle of wine. It did give an idea of what Glo was like, but couldn’t match up to actually having one right here to play with and use regularly for a couple of days.

Anyway, on to the review:

Hands-on at last!

Unlike the last time we reviewed a Glo, this one came with the full retail packaging. The lid of the sturdy box comes off to reveal the Glo itself in a plastic tray; lift the tray out and you’ll find another one holding a USB cable, cleaning brush and warranty card.

Glo, unpacked.

Glo looks and feels very different from the iQOS. Instead of a slim tube about the size of a medium cigar, it’s more similar to a single-18650 box mod. In fact, although I haven’t taken it to bits, I suspect that’s what powers it. The wider edge of its nicely round aluminium body is exactly the right size to hold an 18650.

The device feels well-made and solid, without being too heavy – it’s noticeably lighter than a slightly smaller box mod. The end caps are grey plastic, with a glossy finish on the top one. The top cap also has a cover that slides open to reveal the NeoStik holder. On the bottom there’s a micro-USB charging port and a small plastic flap with a ring of tiny holes in the middle. Closed, this allows enough airflow for the device to work; slide it towards its hinge and let it go, and it springs open to allow access for the cleaning brush.

The bottom cover opens for cleaning.

Apart from that there isn’t a lot to see. Everything is operated by a single metal button on the front of the device, set in an LED-illuminated ring. Well, I say “everything” but there isn’t really much to control except for turning it on.

To use the Glo, all you have to do is slide the top cover back and insert a NeoStik into the hole. Push it down until there’s only about an inch sticking out the top – it sometimes seems to stick a bit near the bottom, but you won’t break it. Then all you have to do is press the button and wait.

Glo seems to heat up slightly faster than iQOS – probably because it only goes to 240°C, instead of 350°C – and you can easily tell when it’s ready. Firstly, the LED ring around the button progressively lights up; when it’s fully illuminated you’re ready to go. Just in case you get distracted the device will vibrate and buzz when it’s at running temperature. Then all you have to do is start puffing.

When the device thinks the stick is done it will vibrate again and turn itself off; just pull out the stick, dispose of it and close the top cover. If you use it the way you’d smoke it runs for long enough to take ten or a dozen puffs – just like a cigarette. The question is, does it deliver the same experience?

Using the Glo

My Glo came with two packs of NeoStiks, one each in Menthol and Bright Tobacco flavour, both carrying the Kent brand. I played with the device for a few days, vaping a menthol stick every couple of hours as a change from my e-cigs – my plan was to keep the regular tobacco sticks for a full-day trial, as I was never a menthol smoker. I also cut one of them up for the last article.

I have to say, though, the menthol sticks were pretty good. The taste and sensation they delivered were exactly like a Consulate or Marlboro menthol, so these sticks are a definite win. If you smoke menthols right now, I think you’re going to like the Glo.

Ready to go!

Anyway, last Friday morning I made sure the Glo was fully charged, put all my e-cigs away in a cupboard for the day, and broke out the bright tobacco sticks. I loaded one into the device, hit the button and waited for it to heat up. Then I vaped it.

Well, it was pretty good. It wasn’t like the high-tar cigarettes I used to like, but if you smoke Marlboro Gold it’s very close to that experience. There’s no shortage of nicotine hit, and the vapour replicates the taste of cigarette smoke very well.

One stick isn’t much of a test though; what I wanted to know was, could I use the Glo all day? Would it be satisfying enough to keep a smoker off the cigarettes? So, after my first stick, there were nineteen more to go. And I got through them all.

It worked, too. At no point did I feel that the sticks weren’t satisfying enough, and I usually sub-ohm 24mg e-liquid. I found myself reaching for the pack of sticks about every 40 minutes through the day. Using it was easy, too, and I didn’t find the short wait for it to heat up all that annoying. Once a stick is finished you can just drop it in the bin – there’s no need for ashtrays, and you won’t get flakes of ash all over the place either.

One thing I did notice was that there’s a distinct tobacco smell. By the end of the day my office smelled as if someone had smoked a couple of cigarettes in it. That was completely gone by next morning, though, with no stale aroma hanging around. Would it become more persistent if you used Glo every day? I don’t know the answer to that one.

Compared to iQOS the Glo isn’t quite as satisfying, probably because of its lower running temperature. To compensate, it’s a lot easier to use because you don’t need to worry about battery life so much.

When we first discussed the Glo, one interesting point was the claimed battery capacity. iQOS needs to be recharged frequently; the larger Glo packs in a lot more power storage, and BAT said a single charge would be enough to vape more than 30 NeoStiks. I admit to being sceptical about this, but it’s true.

After vaping a full pack of twenty sticks, the power indicator – that LED ring around the button again – showed the battery still had half its charge left. That’s pretty impressive, and means a single charge should keep a Glo in action all day.

Our verdict

Does Glo deliver exactly the same experience as smoking? Not quite – but it’s very close. If e-cigarettes don’t quite do it for you this gadget will definitely be worth a try when it starts appearing in your market.

Inside the NeoStik

A couple of months ago we looked at what’s inside one of the Heets that PMI’s iQOS is fed with. That’s turned out to be quite a popular post, which isn’t really a surprise. After all, it’s an exciting new technology and people want to know how it works.

Heat not Burn UK is an impartial site, though, and we don’t want to give too much free publicity to PMI, so the next two posts will be dedicated to British American Tobacco’s Glo. This has featured in our articles before, and we even did a limited review of it, but now we’re in a position to go a bit further. Although Glo has only been released in a couple of test markets so far, we now have one and a supply of NeoStiks for it. The next article here will be a full review of the Glo, based on using it exclusively for a couple of days.

This time we’re going to look at the innards of a NeoStik, just to see how it compares to a Heet. The two products are very similar in concept, so as you’d expect they’re put together quite similarly as well. The most obvious difference is the shape – NeoStiks are much longer and slimmer than Heets, so there’s no way to use one kind of stick in the other kind of device.

We’ll look inside a NeoStik in a minute, but first let’s go back to something that’s been said on this blog a few times – that you can’t put a Heet or NeoStik in your mouth, light the end and smoke it. Well, I still don’t know if you can do this with a Heet (and I suspect you can’t) but with a NeoStik? Yes, you can. They burn just like a normal cigarette, so you can smoke them. It’s not a good idea, though.

For a start, they only last for a few puffs, so even if the sticks end up being significantly cheaper than cigarettes it would be a very expensive way to smoke. The other problem is that after those few puffs there’s a strong taste of burning plastic. The internal components of the NeoStik are made to resist its operating temperature of about 240°C; if you light it things get much hotter. The smoke from a burning NeoStik isn’t any healthier than a cigarette, and once you start inhaling the plastic bits it’s probably a good bit worse. So don’t smoke them.

Investigating the NeoStik

Let’s assume you’re going to be sensible and use your NeoStiks in your shiny new Glo, like you’re supposed to. What exactly is it you’re slotting into the gadget?

Like a Heet, a NeoStik sort of resembles a miniature cigarette. However, where a Heet is the same diameter as a cigarette but much shorter, a NeoStik is about the same length as a cigarette but much slimmer. Here’s a side by side comparison of the two. If the Heet looks a bit scruffy that’s because it’s the empty paper from the one that was dissected for the article back in June, but you can still get a good idea of the size:

Heet (front) and NeoStik

The NeoStik on its own is a very neat, slim item. As you can see from the grid on the board, it’s about 84mm long – the same length as a standard king-size cigarette. It’s only about half the diameter though. So anyway, what’s inside it? Time to get the scalpel out and slice it down the middle:

Straight away we can see why it’s possible to smoke a NeoStik. Unlike the Heet, which contains a small plug of rolled, reconstituted tobacco sheet, half the length of the NeoStik is filled with what looks like normal cigarette tobacco. So that answers that one. Now, what’s the rest of it?

Unfortunately the NeoStik couldn’t be dismantled the same way as the Heet could, because apart from the tobacco all the bits are firmly glued to the paper and can’t be removed without ripping the whole thing to shreds. It’s possible to see what’s in there, though.

Just above the tobacco is a rigid plastic lining that extends the full remaining length of the stick. Over half of it is empty, and there’s nothing between this empty section and the tobacco, which is why there are little bits of shredded leaf visible inside it in the photos – the scalpel blade pulled them with it. However, unless you cut the stick up the tobacco is firmly packed enough that it won’t go anywhere, and it wouldn’t matter much if it did.

Next there’s the filter. Like the Heet’s filter it’s very short, probably so it doesn’t absorb too much of the vapour. With these products there isn’t really any need for much of a filter, because the vapour contains little or no solid particulates. Finally, the end that forms the mouthpiece is empty – there’s just the plastic lining to keep it rigid.

A familiar concept

So the internal structure of a NeoStik isn’t that different from a Heet; it has most of the same parts, although they’re put together differently. This is probably because it works in a different way. The iQOS has a blade that the Heet is pushed down onto, and when the device is switched on this heats  up.

Glo doesn’t have a blade; if you open the cover on the air intake at the bottom you can look right through the device. Instead, there’s a heating coil around this tube; it heats up the part of the NeoStik with the tobacco in it. If you look at a used stick you can see where the heat has slightly darkened the paper in and above this section:

So there you have it. This is BAT’s take on a heat not burn product, and while it follows the same principles as iQOS there are a few tweaks to how they’ve done it. How does it compare? The next article will be all about that!
