Heat not Burn takes off in South Korea

When someone mentions Korea most of us think of the mad regime in the North. That’s a pity, because South Korea is much nicer – and, if you’re a fan of Heat not Burn, it’s also a lot more interesting right now. South Korea is now an expanding market for the leading HnB products, so much so that a local company is planning to join in.

Unlike its bizarre Stalinist neighbour South Korea is an advanced industrial country, with a relatively low smoking rate of 19.9% – slightly lower than Germany, but slightly higher than Japan. It also has tough anti-smoking laws that make it illegal to light up in almost any public place. The government is pretty serious about persuading its citizens not to smoke.

Unfortunately it has a couple of serious problems. The first, and probably the biggest, is the army. The country has the world’s sixth-largest standing army and second-largest reserves; in total it can mobilise 3.7 million troops, and all South Korean men have to do an obligatory 21 months of military service. This is a great way to defend against insane, highly militarised neighbours, but not so good if you’re trying to stub out smoking.

Soldiers smoke, often because it gives you something to do while you wait for the army to decide what’s happening to you next, and lots of Koreans pick up the habit while they’re in uniform. That 19.9% smoking rate? It breaks down into around 5% of South Korean women, but about 40% of men.

At the same time, vaping hasn’t really taken off in Korea the way it has in the UK or USA. It is possible to buy e-cigarettes, and there are some local manufacturers, but it hasn’t made a big dent in the smoking figures. Now, major tobacco companies are wondering if Heat not Burn can do a better job.

Here comes iQOS

HnB products are very new to the South Korean market; Philip Morris released its popular iQOS device on 27 May, and now has two stores in Seoul (if you like Korean music you’ll be pleased to hear that one of them is in Gangnam). They’re also selling the iQOS through the CU convenience store chain, which has about 3,000 branches across the country.

Philip Morris say they don’t have any firm sales figures yet but are seeing “growing popularity”. That sounds about right; an employee at a CU store says, “They have been all sold out every day.” It wouldn’t be surprising if this is the case because iQOS continues to do very well in Japan; it took a 0.8% share of the cigarette market in the first quarter of 2016, but had climbed to 4.5% by the end of the year. PMI say it’s now at around 7%.

With the iQOS apparently doing well in South Korea, British American Tobacco are aiming to introduce their rival Glo device in August. Glo is a similar format to iQOS and BAT Korea say they’ll be selling it at a slightly lower price. If they can get the device and its NeoStiks into enough shops it’s likely to catch on too.

A home-grown rival?

The global tobacco companies can’t expect to have it all their own way, though. HnB devices are consumer electronics, and when it comes to developing and manufacturing these South Korea is one of the world’s giants. The country that’s home to companies like Samsung and LG isn’t likely to let imported electronics flood its home market, is it?

No, it’s not. Clearly impressed at the popularity of the new technology, one of South Korea’s own tobacco companies is already looking at moving into the market. KT&G (it stands for “Korea Tomorrow & Global”, but used to be “Korea Tobacco  Ginseng”) is the country’s largest tobacco manufacturer. It’s a major player locally, with 62% of South Korea’s cigarette market, and its Esse superslim brand is also popular in Russia and Eastern Europe.

Now KT&G want to release a HnB product to take on Glo and iQOS – and they’re not hanging around. According to the company they’ve been watching the heated tobacco trend since 2012 and want to have their own device on the market by the end of this year.

That’s quite an ambition. If they can pull it off, they’ll be in on the ground floor with PMI and BAT. The multinationals will have a bit of a head start, but not enough to let them build up real dominance, and that’s likely to be balanced by consumers’ familiarity with KT&G brands.

The real question is what will the product be like? Unfortunately KT&G haven’t released any details yet, but if they think they can get in on the shelves by the end of the year – even as a trial product – then its design must already be fairly advanced. A HnB device isn’t something you can just throw together; PMI have invested more than $3 billion in iQOS so far, and BAT can’t have spent much less on Glo.
iQOS is the latest version of a basic concept first trialled in 1998, as Accord, then redeveloped in 2007 as Heatbar.


So will it happen?

If KT&G are going to have any chance at all of getting a product on the market by December, it would need to be pretty much ready to go into production by this point. That means it would need to have been tested already, and probably tried by a good number of consumers to get their feedback on it. If this has been done, it’s been done unusually discreetly – we can’t find any details or images of a KT&G device anywhere.

Of course, South Korean companies are very good at keeping innovations quiet until they’re ready to start marketing them, so it’s very possible that KT&G really do have a product ready to launch over the next few months. If they do, it will be interesting to see how it compares to
iQOS, Glo and other existing devices. Hopefully we’ll know more about it – and whether it will be marketed outside South Korea – soon.

iQOS Update – What’s Inside A Heet

One of the most popular pages on this site is our review of Philip Morris’s innovative iQOS device. That’s not much of a surprise, because iQOS has probably had more publicity than any other Heat not Burn product and it’s also the most widely available. It’s steadily rolling out beyond the first test markets and can now be bought in the UK, Spain, the Netherlands and several other countries; before too long it will be available globally, and I think it’s going to be a huge success.

When Heat not Burn UK first tested the iQOS the only sticks that came with it were mild menthols. Those were not as satisfying as they could have been, but did prove the concept. Happily, during our visit to PMI’s research centre at Neuchatel a couple of months ago there was no shortage of them in all flavours, and I got the chance to try an iQOS with a full-strength stick. I’m happy to report that it was very close to the experience of smoking a Marlboro, and an excellent substitute in every way.

Sticky Stuff

Obviously, what made the difference between “Meh, this is okay” on the first iQOS test and “Wow!” on the second one was the sticks it was being fed with. That means it’s probably time to look at the sticks themselves in a bit more detail.

The baby cigarettes that go in the end of an iQOS were originally called HeatSticks, but they’ve now been rebranded as “Heets from Marlboro”. Currently Heets come in three flavours – Amber, which roughly equates to full-strength Marlboro Red; Yellow, a lighter Marlboro Gold; and Turquoise, the mild menthol version. As far as I can tell these all have the same nicotine content, and the only difference is in the flavour.

Anyway, I just called them baby cigarettes. They’re not. Yes, they look like baby cigarettes, and they come in a tiny pack of twenty, but you can’t stick them in your mouth and fire them up with your trusty Zippo. That just won’t work. Even if it did work it would be pretty pointless, because the whole idea is that you don’t burn the tobacco.

In fact there really isn’t a lot of tobacco in there to burn, anyway. Looking at a Heet, you can see that the filter seems to take up about three-quarters of its length:

There are quite a few bits in here.

Not Just Tobacco

It’s not quite this simple, but we’ll come back to that. What’s in the other quarter is the stuff that gets heated, and I’ve actually had the chance to watch it being made in the factory at Neuchatel. PMI made me promise not to put all their trade secrets on the internet, but I can tell you the basics. What they do is blend selected tobaccos to get the flavour they want, then grind them to a fine powder. This is then mixed with water and some other ingredients – vegetable glycerine to keep it moist and generate the vapour; natural cellulose fibres to bind it; and guar (a natural gum) to hold the whole lot together.

This liquid mixture is sprayed onto a conveyor belt, run through a dryer then peeled off in thin sheets. The brown stuff in the end of a Heet is those sheets, rolled up like tobacco leaves in a cigar. When you load a Heet into your iQOS a steel blade in the device cuts into the roll, and when the blade heats up it creates the vapour for you to inhale. That vapour is mostly VG, loaded with aromatic flavours from the tobacco – which is why iQOS can replicate the flavour of a cigarette in a way that e-cigs can never quite manage.

So what else is in a Heet? Well, it’s not just the filter. In fact the filter itself is very short, as you can see:

From left to right: The tobacco, hollow tube, PLA and filter.
The actual filter is even smaller than the plug of tobacco at the other end, and it’s really only there to give you the familiar feel of a cigarette filter. Because iQOS doesn’t produce all the harsh combustion compounds you get from a cigarette there’s no real need for much filtration, so it can be very short. In fact if it was much longer it would probably soak up a lot of the VG vapour that you want to inhale.

After the filter is a loose roll of PLA, a very stable, food-safe plastic material. This is what does the real work; it slows the vapour down without absorbing it, giving it time to cool to a more pleasant temperature before you inhale it. This takes up almost half the length of the entire Heet.

Between the PLA and the tobacco is a short length of hollow tube, made of a similar material to the filter. As far as I understand it this is mainly to keep the blade away from the PLA and give the vapour a clear path to start its journey through the Heet. Then finally, at the end, you’ll find that little plug of tobacco.

Small But Complicated

So a Heet might look like a cigarette, but inside it’s a bit more complicated. This, and the fact they’re so small, means they’re also trickier to make; PMI had to do some creative rebuilding of some old but reliable cigarette-making machines to come up with something that would make Heets.

All this effort has paid off, though. It might be tiny, but a Heet will give as many puffs as a full-size cigarette. If you get the strength that suits you those puffs are just as satisfying, too. I had a few lingering doubts about iQOS after my first experiment with it in Poland last year, but using an identical device with Amber Heets was a totally different experience.

What’s most exciting is that, while iQOS isn’t the first generation of this technology, it’s still at a relatively early stage; there’s a lot of potential for development in there. I’m increasingly sure that HnB products like this have a very bright future in front of them.

If you are looking for HEETS we now sell them in our online store.

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 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.
