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.

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.

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.

E-cigs don’t work everywhere – Heat not Burn does

I’m a freelance writer, and I love e-cigarettes. Since I switched to vaping my desk isn’t cluttered with smelly ashtrays anymore, and I don’t have to brush ash off my keyboard twice a day. I spend most of the day at my PC, so I can keep a charger on the desk for my batteries and there’s a nice long USB cable for pass-through mods. The top shelf in one side of the desk holds an assortment of e-liquids; in my job, vaping works perfectly.

On the other hand, before I became a writer I spent years in the British Army. Like many soldiers I smoked, and I remember a lot of early mornings happily puffing away in some cold, wet forest. No matter how soaked, frozen and miserable you get, a cigarette is a reliable way to inject some very welcome morale into your life.

The thing about cigarettes, of course, is that they couldn’t be simpler. You take one out the pack, stick the brown bit in your mouth and set fire to the other end. Unless you’ve let them get soaked, or you’ve sat on the packet and squashed them (a waterproof tobacco tin will avoid both these issues) they’re guaranteed to work.

War is hell – for e-cigs

But how is an e-cig going to cope with the hardships of a soldier’s life? All the liquid is probably going to leak out, turning the contents of your pocket into a slippery mess. The tank’s probably going to get broken the first time you trip over a stump in the darkness and fall flat on your face. The ability of most box mods to survive being soaked with rainwater is pretty dubious. Worst of all, your batteries aren’t going to last forever and there won’t be any USB ports in the tree you’re living under. E-cigarettes are great as long as you’re surrounded by civilisation, but they’re not going to work out in the field.

It isn’t just soldiers, either. What if your workplace is the deck of a trawler? The first wave that knocks you down, and leaves you flailing around in a pool of seawater and fish guts, is going to destroy every electronic device in your pockets. Let’s not even start thinking about rebuilding a coil in a cramped cabin that’s rolling through sixty degrees.

So it’s pretty obvious that there are some people who e-cigarettes just aren’t going to work for. But does that mean they’re doomed to a lifetime of smoking? Not so fast. There’s probably a heat not burn product that’s going to work just fine.

What’s the solution?

Last month I visited Philip Morris International’s research facility at Neuchatel in Switzerland, where they’re making the Heets that feed their iQOS device as well as working on the next generation of HnB technology. It was a very interesting visit – I’ve already discussed their latest research on safety – and left me feeling very optimistic about the future of heated tobacco products. There were some lively discussions, too, and during one of these I explained that I’d been a soldier for a long time and, based on my experiences, I didn’t think iQOS was going to be much use in the field. The PMI rep didn’t even blink. “We know,” she said. “That’s why we’re working on three other products.”

One of those products is the Mesh e-cigarette, which is already on the market. I have one, and it’s pretty good; the Mesh is an extremely simple and fairly sturdy gadget, and its disposable cartridges are more compact and probably a lot tougher than cigarettes, but if you’re doing hard work outdoors in bad weather it has the same drawbacks as any other e-cig; it isn’t very waterproof, and it needs charged a couple of times a day. Then there’s a completely different product in the development pipeline that isn’t HnB, but isn’t an e-cig either; it uses a chemical reaction to create a nicotine-containing vapour. The interesting thing about this is that it doesn’t need any batteries, so it might be a good solution for people who don’t have regular access to a charger; that depends on how robust it is, and I can’t comment on that because I haven’t seen one yet.

That’s three of PMI’s Smokefree nicotine products. The fourth one is a heat not burn product that uses the same concept as RJ Reynolds’s Revo. It’s a disposable item that contains a stick of processed tobacco and a charcoal pellet that provides the heat. All you have to do is light the pellet and puff away.

Revo isn’t really a new product; it’s basically a rebranded version of the 1990s Eclipse, which was a complete flop. Reynolds relaunched it under the new name because they decided the market had moved enough to make it viable this time around, but it’s still basically the same thing. I’m not very familiar with it but I do have some doubts about how effective it is.

So far, at least, those doubts don’t apply to the PMI product, which the company are currently calling Platform 2. It works on the same principle as the Revo, but it’s a completely new design. That gives PMI a chance to iron out any bugs, and hopefully come up with something that delivers a consistent vape with no risk of accidentally burning the tobacco.

Keeping it simple

The benefits of this sort of design are obvious. If you can manage to smoke, you can use a HnB product like Revo or Platform 2. It works exactly like a cigarette; you just have to take it out the pack, put it in your mouth and light it. There’s nothing fiddly to play with, it doesn’t need electricity and it’s no more vulnerable to the weather than a cigarette. In fact it’s probably less likely to get damaged by water; Revo has a metal foil tube to hold the tobacco, which is a lot more waterproof than cigarette paper.

A lot of smokers have switched to vaping – probably over ten million by now – but it’s not going to work for everyone. Improved technology will eventually increase battery life and make the hardware easier to use and more robust, but it’s not likely e-cigs will ever be as simple as a traditional cigarette. Heat not burn has the potential to solve that problem, because the basic principle – get some tobacco and heat it – is a lot more flexible. Inside a few years there will be HnB products that anyone can use, no matter how tough their job is.

Heat Not Burn Safety Update

the cube neuchatel

Over the last year we’ve seen a lot of progress for heat not burn products, with the iQOS now available in several countries including right here on this website and a few new devices set to be released soon. The market looks like it could be on the brink of some serious growth, and within a few years HnB could have made as big a dent in smoking rates as e-cigarettes already have.

There’s one thing still missing, though. If heated tobacco products are really going to grab a sizable percentage of the cigarette market it’s important that their makers can show they’re safer than smoking. As we’ve mentioned before, common sense tells us they pretty much have to be a lot safer, because the tobacco isn’t being burned, but there’s a distinct lack of actual data. Isn’t anyone doing the research on this? It turns out the answer is yes.

Of course, you won’t see this research appearing in the medical journals just yet, because it’s actually being carried out on behalf of the tobacco industry. Philip Morris International have invested more time and money in HnB than anyone else, and a lot of that has gone towards looking into how much risk can be removed by switching from lit to heated tobacco. Some world-class laboratories have been asked to investigate how HnB is working and what that means in terms of health effects. Last week Heat not Burn UK got a chance to visit the Cube, PMI’s European research HQ at Neuchatel in Switzerland, to find out what’s going on.

How hot is too hot?

By now everybody knows that smoking-related diseases aren’t caused by tobacco; it’s the combustion process that creates the worst toxins and cancer-causing substances. Tobacco-free herbal cigarettes aren’t any better for you than Benson & Hedges, because you’re still inhaling burning plants. However, PMI have found out that making a safe HnB product isn’t as simple as not setting fire to the tobacco.

The tip of a lit cigarette, between puffs, is at between 600°C and 800°C; when you take a drag on it this rises to over 900°C. That’s the sort of temperature tobacco burns at. However, at much lower temperatures it goes through a process called pyrolysis, where it’s being broken down by heat but not actually burning. Pyrolysis starts at around 350°C, much lower than combustion temperatures – and pyrolyzing tobacco still gives off a lot of nasty chemicals. Not as much as burning it, of course, but probably still more than you really want to be inhaling.

So the trick to safe HnB is to heat the tobacco to just below the point where pyrolysis begins. If you were wondering why iQOS heats its sticks to 350°C when tobacco doesn’t start burning until hundreds of degrees above this temperature, now you know. PMI have opted for the highest safe temperature, where there’s little or no pyrolysis going on but the tobacco is still hot enough to generate a decent vapour. Because HnB products like iQOS, Glo and PAX 2 are electronically controlled it’s easy to get them to produce a constant temperature and avoid pyrolyzing or burning the tobacco.

Tracking the toxins

Obviously the big question is, what effect does HnB have on the levels of chemicals you’re inhaling? It’s unrealistic to insist on zero chemicals, because many of the toxins in cigarette smoke are very common substances. For example, smoke contains high levels of formaldehyde – but human bodies contain formaldehyde, too. Our metabolism produces it, and there are detectable levels of it in exhaled breath. What we’re looking for are levels that might not be zero, but are much lower than you’d get from a cigarette.

To test this, PMI analysed the smoke from a reference cigarette – this is a standardised cigarette used for lab testing – then compared it with the vapour from their two HnB products. One of these is iQOS; the other, known as Platform 2, hasn’t been released yet but works in a different way. What they found was that for every chemical they tested, levels were dramatically reduced in both HnB products. The highest levels were for ammonia, with iQOS having about half the level of a cigarette and Platform 2 around 40%. Is that enough to worry about? No; even cigarette smoke doesn’t have anywhere near enough ammonia to be an issue. For the other chemicals they tested levels were reduced by at least 80%, and in most cases 90 to 95%. Overall it looks like HnB eliminates more than 90% of the harmful chemicals found in cigarette smoke.

One impressive point about PMI’s research is that they’ve been extremely thorough. Different agencies have different lists of chemicals in smoke that concern them. For example the FDA have a list of 28 different substances; the International Agency for Research on Cancer’s list has fifteen. To be on the safe side, Philip Morris have simply combined everyone else’s lists; they test for fifty-eight different chemicals – far more than anyone else does.

Attention to detail

PMI aren’t just measuring what’s in the vapour; they’re also testing smokers who’ve switched to their HnB products to see how they compare with people who’ve either quit entirely or continued to smoke. What they’re doing here is looking to see if switchers’ blood chemistry is more like a smoker or a quitter. For every chemical they’ve tested – including carbon monoxide, benzene and acrolein – HnB users either have identical levels to smokers who’ve quit entirely or (for acrolein) the level is slightly higher than a quitter but much lower than a smoker.

At Heat not Burn UK we might not be scientists, but we do know how science is supposed to be done. The research that’s being carried out on the health effects of HnB is very good science. It’s extremely thorough and detailed. The actual analysis is being carried out by independent labs, which should deal with any accusations of bias. PMI are being completely open about the experimental methods, so anybody who has doubts can replicate the research themselves.

Why so modest?

That leaves one question: With all this research to back them up, why aren’t PMI shouting from the rooftops about how safe HnB really is? Most likely that’s down to an understandable wariness of being sued. If they say that iQOS is 90% safer than smoking, and then at some point in the future evidence shows it’s only 89.9% safer, how long is it going to be until swarms of Californian lawyers descend on them with a fistful of class action suits? Not long, probably.

So, for now, they’re playing a cautious game. The data is there, and steadily growing. Sooner or later it will be presented to some government agency, probably the FDA, and they’ll confirm that these products are much safer than smoking. That’s when the manufacturers will start publicising it. Until then we’re just going to have to rely on common sense.

BAT’s glo – sneak preview

A couple of months ago we looked at BAT’s glo, their stick-fed iQOS rival that’s currently being trialled in Japan. It still hasn’t been released in other markets, and BAT haven’t revealed their plans for it yet, so it could be a while before smokers in the UK have a chance to try it. Just so you know what you’re waiting for, however, Heat Not Burn UK set out to track one down. It was a struggle, but last week one of our agents finally managed to get his hands on the elusive device.

Because of how our glo was obtained (no, we didn’t steal it) it didn’t come in its usual retail packaging, so that won’t be included in this review. It did come with a full pack of Bright Tobacco sticks to feed it with, so it was thoroughly tested as well as being poked, prodded and generally fiddled with. So what’s it like?

The device

The Glo is a neat, simple device. The silver oval on top slides to reveal the NeoStik socket.

The glo device looks like a small, simple box mod e-cigarette. It’s about the height and thickness of a pack of cigarettes, and maybe two-thirds of the width. The aluminium body is rounded on both sides, making it comfortable to hold, and it’s not too heavy. It does feel solid and well made, and the build quality looks excellent. The end caps are textured plastic, the metal body has a nice satin finish and there’s a laser-etched glo logo on the front.

Looking at the top, there’s an oval silver cover. On the bottom is a micro-USB charging port and a small cover that looks like it should open, but was left well alone in case it broke. After some discussion we think that’s the airflow vent; there has to be some place for air to flow into the heating chamber so you can inhale the vapour, and we couldn’t see anything else that might do that job.

The only actual control on the glo is a single button on the front. Its placement looks odd if you’re used to e-cigs; most box mods now have the fire button on one side, because that way it falls naturally under your thumb. However the glo’s button is just the on/off switch, and you won’t need to touch it when you’re actually using the device. The button itself is metal and surrounded by a ring of translucent plastic, which turns out to be LED-illuminated – but we’ll get to that.

The Tobacco

Like the iQOS, glo uses cigarette-like sticks which BAT call NeoStiks. Compared to PMI’s HeatSticks these are longer and slimmer – almost exactly the same size as a traditional cigarette. Instead of a filter there’s a hollow plastic tube, which makes sense – why fit a filter when there’s no smoke? The centre of the stick is filled with finely shredded tobacco. Actually it looks like the bottom is, too, but BAT say that’s not tobacco. It could be shredded cork or something similar.

In Japan the NeoStiks are priced about the same as normal cigarettes, as are iQOS HeatSticks. Industry gossip suggests the reason for this is that nobody’s quite sure how they’ll be taxed yet, so BAT and PMI are both playing it safe. If they end up being taxed at a lower rate the price may fall in the future.

Some of the stuff inside is tobacco. Some, according to BAT, isn’t.

How does it work?

Using the glo is very simple. The cover on top slides to one side, revealing a hole about the size of a cigarette. All you have to do is insert a NeoStik into this hole until it won’t go any further. This is quite simple, like the iQOS, as long as you don’t rush it.

Once the stick is fully inserted all you have to do is press the button to turn the glo on, then wait for it to warm up. Progress can be tracked by watching the surround on the button; this progressively lights up as the coil temperature rises, the glow of the LEDs advancing clockwise wound the circle, and when the whole thing is illuminated it’s ready to go. Just in case you miss that the glo will also vibrate with a faint buzz when it reaches operating temperature. Then all you have to do is take a puff.

So the big question is, what’s it like? The answer is that it’s very good. Our agent was lucky enough to try the iQOS and glo together, and thinks the glo is just as good at producing vapour and has a slightly better taste. This was a bit surprising, as it runs at a much lower temperature – 240°C, rather than 350°C for its PMI competitor.

Each stick gives about as many puffs as a traditional cigarette, and when the glo decides you’ve fully vaped it, the device will vibrate again and turn itself off. This seems to be aimed at making sure you don’t overheat the tobacco to the point where it starts producing nasties.

Looking at the used stick was interesting. The heat seems to be applied in a narrow ring, just below the end of the plastic tube. It’s hard to say how much of the tobacco is being affected by it. On the other hand it doesn’t matter much, because whatever the glo is doing, it works.

Conclusions

The overall concept of glo is very similar to the iQOS, but BAT have taken a different approach to the hardware. Our first impression is that this has paid off. Battery life is much better than the PMI device – although it’s hard to say yet if it lives up to BAT’s claims of a 30-stick life between charges, because we didn’t get that many sticks. The downside is that the device itself is much bulkier, and unlike iQOS you certainly can’t hold it like a traditional cigarette.

It does seem to do the job, though. There’s a satisfying amount of vapour and the taste is very good. The device itself is simple and well made, and disposing of used sticks is a lot less messy than emptying an ashtray. This is a very interesting product, and if it’s released in the UK we think it has a lot of potential.

iFUSE – the Heat not Burn hybrid

There’s more interest than ever before in safer alternatives to smoking, with millions of smokers either thinking about moving to new technology or already having taken the plunge – mostly with electronic cigarettes. E-cigs aren’t for everyone, though. Many smokers have tried them and found that they didn’t really work for them; some have been put off by misleading newspaper articles claiming that vaping is just as unhealthy as smoking; still more simply don’t want to give up their real tobacco.

Heat not Burn technology is the new hope for smokers who want that authentic tobacco taste, and although the devices aren’t all that widely available yet they’re steadily being rolled out. iQOS is now on sale in the UK, for example. By the end of the year HnB products should be on sale in a lot more places, giving a new option for smokers.

HnB or e-cigs – What’s better?

It’s likely that the next few years will see a lot of arguments about which technology is better – e-cigs or HnB. They both aim to do the same thing, but take different approaches to it, and we can safely assume that each side will have plenty of enthusiastic supporters. Which will win in the long run? Who knows? However, British American Tobacco have already tried to combine the best of both worlds with their iFUSE device.

So what’s iFUSE? Basically it’s a hybrid device that starts with a fairly standard e-cigarette, then adds some elements of HnB technology aimed at creating a more authentic tobacco taste. It’s an interesting concept, so have BAT managed to get it to work?

If you’re familiar with latest-generation tobacco industry e-cigs like PMI’s Mesh, the iFUSE will have a familiar feel to it. The designers have obviously put a high priority on making it easy to use, and they’ve done a very good job of that. It isn’t quite as simple as the Mesh, but then nothing is as simple as the Mesh – and the iFUSE has a lot more going on inside.

Externally, there are two visible components. The battery is a fairly standard looking unit about the size of an eGo battery, but with a more flattened cross-section. It feels well-made and has a nice rubberised coating which, along with its light weight, makes it very comfortable to hold. There’s a USB charging port and a single large button, which appears to be metal and has a reasonably nice clicky feel. It’s not up to the standard you’d expect on a high-end e-cig, but then the iFUSE device costs just £14.99. At the top end of the battery is a proprietary connector for the cartridges it uses, which we’ll come back to.

The cartridge isn’t visible when the iFUSE is assembled; a large cover, which BAT call the mouthpiece, slips on over it. This is in two parts – the actual mouthpiece is black plastic, and is inserted into the end of a metal cone that covers the cartridge. The cones are available in a couple of different colours – silver and gold ones are for sale through the iFUSE site, but the same site has illustrations of some more options. Presumably they’ll be available soon.

When it’s all put together the overall effect is a simple, clean-looking little device. It’s not much larger than a standard eGo-type electronic cigarette, and no heavier. It is bulkier than an iQOS, but not by much – and it feels lighter, too.

Meet the Neopod

It’s inside that the iFUSE does things differently. It’s fed with disposable cartridges which BAT are calling Neopods; these carry the Kent cigarette brand, and they come in three flavours so far: Tobacco, Crisp Blue and Winter Green. Each Neopod is plastic, slightly tapered and a couple of inches long; inside it are three components, one of them unique to the iFUSE.

At the bottom of the cartridge, where it plugs into the battery, is a standard heating coil. This is fed from a reservoir of nicotine-containing liquid, which seems to be similar to regular e-liquid for an electronic cigarette. That’s what produces the actual vapour you inhale, so no surprises there. Where the Neopod is different from a Mesh or Vype Pen cartridge is that above the liquid tank, and directly below the mouthpiece, is a cylinder of finely chopped tobacco.

To use the iFUSE you just turn it on by pressing the button three times, and take a puff. It has an auto switch, so there’s no need to press the button every time you inhale, and because it’s creating the vapour from e-liquid there’s no need to let it warm up. This is an irritation with the iQOS; having to wait for the coil to reach running temperature isn’t exactly spontaneous. The iFUSE, on the other hand, is ready to go right away.

When you inhale the coil activates, vaporising some of the liquid. This is then drawn through the tobacco capsule, heating it and releasing the complex aromatics that give cigarette smoke its taste. Instead of being artificially flavoured, like e-cig vapour, you’re inhaling real tobacco flavour.

So does it work?

The iFUSE is a very interesting concept, backed up with simple and nicely made hardware. The only problem is, it doesn’t work very well. There’s a hint of tobacco flavour, but not really very much of it. The vapour itself is also quite thin, and the throat hit isn’t a patch on the Mesh or a conventional e-cigarette. It’s no match for an iQOS either.

Most likely, the problem is that the system just doesn’t apply enough heat to the tobacco. It’s not a full-on HnB product anyway, but the reason things like the iQOS work the way they do is that it takes quite a lot of heat to get a decent flavour from tobacco – and the iFUSE isn’t delivering it. There could be potential for it with a bit more development, but right now it suffers from being neither one thing nor the other. It’s a mediocre e-cigarette, and physics is against it really working like HnB.

It’s disappointing that the iFUSE doesn’t live up to its potential, because it is a nice and affordable little gadget. The vapour delivery is what really matters, though, and it just isn’t there yet. Buy a proper HnB device instead.

WHO notices Heat not Burn

Heat not Burn products are coming to the attention of a new audience – and that might not be good news. The World Health Organisation is gearing up for its latest tobacco control junket and, for the first time, heated tobacco products are on their radar. They haven’t attracted as much of the WHO’s dislike as electronic cigarettes yet, but this could be just a matter of time.

The WHO event is the Seventh Conference of Parties to the Framework Convention on Tobacco Control, which is a bit of a mouthful. Unsurprisingly it usually goes by the less awkward title of COP 7. The previous one, COP 6, was held in Moscow two years ago and attracted quite a lot of bad press. The organisers, who include the UK’s Action on Smoking and Health, seem to be somewhat paranoid, and they claim to be terrified that the tobacco industry will somehow manage to sneak observers in to find out what’s happening. Last year they avoided this risk by first banning all members of the public, in case any were Big Tobacco spies, then banning all members of the press.

As COP is funded from taxpayers’ money not everyone was happy about the oppressive secrecy, especially as some hints of what was going on did slip out. Although it was supposed to be a conference to set tobacco control policy, the reality is that no dissent from the organisers’ position was allowed. It’s been alleged that the health minister of a fairly large country was physically forced back into his seat when he disagreed with one of the proposals. Obviously it’s hard to say if this really happened or not, because any potential witnesses had been locked out.

They’re paranoid, and they are out to get us

This year’s event will be held in India, and it seems the paranoia has got even worse since 2014. The organisers are talking seriously about banning representatives of any government that’s involved with tobacco sales in any way, which is most of them. The Indian government itself might be shut out, despite paying to host the event.

So what does this have to do with heat not burn? The agenda for COP 7 was released last week, but for a couple of weeks before that there has been a sudden increase in interest among tobacco control activists. Anti-smokers have been asking questions about heat not burn on Twitter, mainly trying to find out what e-cigarette users think of it.

Some people were puzzled about this. Why ask vapers for their opinions about heat not burn? Obviously there are connections – both are alternatives to smoking – but they’re very different products. Surely it would have made more sense to ask smokers what they thought, but there was no sign of anyone doing that. Of course that could just have been the usual dismissive public health attitude towards smokers, but was there something more significant behind it?

As it turned out, yes there was. One of the documents the WHO released last week was their new position paper on electronic cigarettes, and as well as e-cigs it mentions heat not burn products. It’s not a big mention, but it’s there – just a single sentence about how the tobacco industry “has launched alternative nicotine delivery systems that heat but do not burn tobacco”.

Bad attitudes

Unfortunately the WHO has been extremely negative about e-cigarettes right from the start, and the tone of this new paper suggests they’re going to be exactly the same about HnB. This probably shouldn’t be a big surprise – the organisers of FCTC lost interest in keeping people healthy long ago. Their priority now is attacking the tobacco industry every chance they get, and heat not burn is an obvious target. After all the leading products are all actually made by tobacco companies, unlike most e-cigs. They contain tobacco, and some of them have well-known cigarette brands. It’s pretty much inevitable that HnB is going to be painted as another evil tobacco industry plot.

So does this attention from WHO mean heat not burn is doomed before it even has a chance to get off the ground? No, not really. Look at what’s happening with e-cigarettes. Yes, the USA and EU have introduced tough new laws – but they haven’t actually banned them, and that’s what the WHO was demanding as recently as last year. There’s now so much evidence they’re safer than cigarettes that even the WHO can’t justify a ban.

It’s almost certain that the same will happen with HnB. Not much research has been done yet, but when the evidence starts coming in it’s likely to show that these products are much safer than conventional smoking. The FCTC crew will huff and puff, but governments aren’t likely to ban the products. They’ll get health warnings, and possibly plain packs, but they aren’t going to be banned except in a few totalitarian states.

Hints of positivity

Actually it could be good news that WHO seem to have been talking to tobacco control people about HnB. While a lot of them are driven by hatred of the industry, some of the more open-minded ones will be interested in anything that gives a safer alternative to smoking. One or two of those were among the ones asking questions, including the chief of an NHS stop smoking service. The same service was the first in Britain to start recommending e-cigs to smokers who wanted to quit; if HnB looks like being a real alternative – and with the current technology it certainly does – it could find supporters in unlikely places.

Sadly it’s a fact of life in today’s world that, whenever something new and enjoyable appears, a lot of people will instinctively want to ban it. Sometimes they succeed, worse luck. More often they manage to cause some problems, but the new technology goes on to eventually become widely accepted. Remember how mobile phones would cause sterility and brain cancer? Now everybody has one. Heat not burn will be opposed by people like the WHO, but the chances are it’s not going to go away. Technology has caught up to the point where it really works, and it’s just going to keep getting better.
