Heated Tobacco vs Vaping: What's Safer in the UK?

Two of the biggest players in the alternative smoking world right now are vaping and heated tobacco. They both offer a smoke-free experience, but they’re definitely not the same thing. From how they function to what you're actually inhaling, they’re completely different beasts, and understanding the differences is key to finding the right fit for your lifestyle.

Key takeaways

➔ Heated tobacco uses real tobacco, while vaping uses a liquid solution (e-liquid), usually made of VG, PG, and flavourings

➔ Heated tobacco warms real tobacco just enough to release nicotine and flavour without burning it. Vaping vapourises e-liquid to produce smoke-free vapour

➔ Heated tobacco closely mimics the actual taste and ritual of a traditional cigarette. Vaping focuses on a flavour-led experience and offers a huge variety of flavours

➔ While both eliminate harmful smoke and ash, vaping has a more established track record as a UK smoking cessation tool and is tobacco-free, unlike heated tobacco.

What is heated tobacco?

Heated tobacco devices, also known as heat-not-burn devices, heat real tobacco within a specific temperature range using an electronic heat-control system. The big difference between this and smoking is that a heated tobacco device warms tobacco just enough to release nicotine and flavour as a vapour, without the smoke, ash, or combustion that comes with smoking. Because these devices use real tobacco rather than e-liquid, the experience is designed to feel closer to smoking a cigarette, both in taste and in ritual.

In heated tobacco products, nicotine is naturally present in the tobacco itself, rather than being added separately as it is in e-liquids. Like vaping, heated tobacco produces no ash or smoke and both can be considered smoke-free alternatives.

What is vaping?

Vaping involves inhaling vapour produced by an electronic device, rather than smoke from burning tobacco. Vape devices heat a liquid solution, which we call e-liquid, to create that vapour. E-liquid is typically made up of VG (vegetable glycerine), PG (propylene glycol), flavourings, and usually nicotine, though nicotine-free e-liquid is available too.

Unlike cigarettes, there's no burning, no smoke, and no ash - just flavoured vapour. It's this fundamental difference that has made vaping one of the most popular alternatives to smoking in the UK. There are so many different types of vapes, from compact pre-filled pod kits to refillable devices. Find out more in our ultimate guide to vaping.

Heated tobacco vs vaping: key differences

Heated tobacco and vaping definitely have some similarities; they’re both electronic, smoke-free, and popular alternatives to cigarettes. But is heated tobacco the same as vaping? Short answer, no.

Under the hood, they work in very different ways, from what goes into each device to how nicotine is delivered and even the experience; understanding these distinctions will help you figure out which option suits you best.

	VAPING	HEATED TOBACCO
Delivery	Uses e-liquid (VG, PG, flavourings, and optional nicotine)	Uses real tobacco in the form of tobacco sticks (e.g. HEETS)
How it works	Heats e-liquid to produce vapour	Heats tobacco without burning it to release nicotine and flavour
Nicotine	Nicotine is added to the e-liquid	Nicotine is naturally present in the tobacco
Smokeless?	No smoke, no ash	No smoke, no ash
Taste	Flavour-led experience, massive amounts of choice	Closer to the taste and ritual of a traditional cigarette
Availability	Yes, nicotine-free e-liquids are widely available	No, tobacco always contains nicotine
Smell	Vapour smell varies by flavour, dissipates quickly	Less smell than cigarettes, dissipates faster than smoke
Cost	A 10ml nic salt at £3.99 lasts a heavy user 2-3 days	Roughly £5 for 20 sticks - pack-a-day cost, every day
Waste	Less consumable waste, plus established UK vape recycling schemes	A used tobacco stick to bin every single time

Is heated tobacco safer than vaping?

Both vaping and heated tobacco are widely considered better alternatives to continuing to smoke traditional cigarettes. But heated tobacco does still rely on tobacco, which is widely agreed to be something you don’t want to ingest.

Here’s the lowdown:

➔ Both options are better than traditional cigarette smoking because neither involves burning

➔ Vaping doesn’t contain any tobacco, but heated tobacco still relies on tobacco as a core part of that experience

➔ E-cigarettes vapourise a liquid solution containing nicotine and flavours, with no tobacco involved

➔ Both remove combustion significantly and reduce levels of harmful chemicals compared to cigarette smoke

What do the guidelines say?

Public health experts at Action on Smoking and Health (ASH) note that while heated tobacco products likely expose users to fewer toxins than cigarettes, they still contain many of the same harmful, cancer-causing substances found in combustible tobacco. This is a major reason why the NHS Guide on Vaping to Quit Smoking points to completely tobacco-free alternatives as a clearer pathway for giving up smoking to significantly reduce your exposure to major toxins.

Heated tobacco products are not currently recommended for smoking cessation by NICE, whereas vaping has a more established track record as a tool to help people move away from cigarettes in the UK.

A comprehensive review published by the UK Government’s Office for Health Improvement and Disparities concludes that, in the short and medium term, vaping poses only a small fraction of the risk of traditional smoking because it bypasses this combustion entirely.

Neither option is entirely risk-free, and the best choice any smoker can make is to quit cigarettes and nicotine altogether.

Vaping vs heated tobacco: which is right for me?

Both vaping and heated tobacco are smoke-free alternatives to cigarettes, and both are a step in the right direction if you're looking to move away from smoking. But when you weigh up the differences – no tobacco, no combustion byproducts, a huge variety of flavours, and a more established harm reduction profile – vaping makes a compelling case for itself.

Whether you're switching from cigarettes, curious about heated tobacco but not sold on the idea of still using tobacco, or simply looking for something that fits your lifestyle better, vaping gives you more flexibility, more choice, and more control over your experience.

And if you're going to vape, you may as well do it properly. At Riot, we've built our e-liquids from the ground up to deliver bold flavour and a genuinely satisfying experience, because we think switching shouldn't mean settling. From our BAR EDTN shortfills to our nicotine salts and the Connex pod system, there's a Riot set-up for every kind of vaper. And for vapers who want more from their vape than just a cigarette alternative, ranges like Kuro deliver premium Japanese-inspired flavour development you won't find in either cigarettes or heated tobacco.

Who's Making Heated Tobacco?

Heated tobacco isn't one product, it's a small category with a few big names. IQOS, made by Philip Morris International, is the one most people have heard of, and it's the market leader by a distance in the UK. BAT's glo is the other major player, built on similar tech: heat the tobacco, don't burn it. Ploom, from Japan Tobacco International, rounds out the big three, though it has a smaller UK footprint than the other two. All three work on the same basic principle — a device heats a tobacco stick or pod at a lower temperature than a cigarette, producing an aerosol instead of smoke, without actually setting the tobacco on fire.

FAQ: Heated Tobacco vs Vaping

Is heated tobacco safer than vaping? ▼

Not based on the evidence so far. Heated tobacco still uses real tobacco, and while it doesn't burn like a cigarette, it produces some of the same chemicals found in cigarette smoke, just at lower levels. Vaping doesn't involve any tobacco at all, and it's been studied far more extensively in the UK, where it's consistently been found to carry a fraction of the risk of smoking. If you're choosing between the two, vaping has the stronger evidence base behind it.

Is heated tobacco the same as vaping? ▼

No. Heated tobacco devices heat an actual tobacco stick to release nicotine and flavour. Vapes heat an e-liquid, which is a mix of VG, PG, flavourings and (usually) nicotine, with no tobacco involved anywhere in the process. Different input, different device, different experience.

Does heated tobacco contain nicotine? ▼

Yes, always. The nicotine comes naturally from the tobacco itself, so there's no nicotine-free version. That's a key difference from vaping, where nicotine-free e-liquids are widely available if you want the habit without the hit.

Is IQOS a vape? ▼

No. IQOS is a heated tobacco device made by Philip Morris International. It heats a tobacco stick rather than an e-liquid, which puts it in a different category to vapes entirely, even though people sometimes lump the two together.

Is heated tobacco allowed on planes? ▼

Generally, yes, in the same way vapes are: carried in hand luggage rather than checked bags, and not used on board. Rules vary by airline and destination country though, and some countries restrict or ban heated tobacco devices entirely, so it's always worth checking before you fly.

Which is cheaper - heated tobacco or vaping? ▼

Vaping, by some distance. Heated tobacco sticks work out at roughly £5 for 20, so it's essentially the same daily cost as a pack of cigarettes. A 10ml bottle of nic salt at £4.99 lasts a heavy user 2-3 days. Add up a month of either and the gap becomes obvious.

Can heated tobacco help you quit smoking? ▼

It's not licensed or recommended as a stop-smoking tool in the UK. Some smokers do use it as a switching product, but because it still involves tobacco, it doesn't break the habit in the same way vaping can. Vaping has a much stronger evidence base as a quit aid and is backed by the NHS as part of a stop-smoking plan.

Is heated tobacco available in the UK? ▼

Yes. IQOS (Philip Morris) and glo (BAT) are both sold in the UK, alongside a smaller presence from Ploom (JTI). Availability is more limited than vaping though, which has a far bigger retail footprint across the country.
