Heat-Not-Burn vs Vaping: What’s Better for UK Users?
If you're trying to ditch traditional cigarettes, you’ve probably heard of vaping — but what about heat-not-burn (HNB) devices like IQOS? These tobacco alternatives are gaining ground in the UK, offering smokers a different kind of “smoke-free” experience. But how do they really compare to vaping in terms of safety, popularity, and user vibe?
What is heat-not-burn?
Heat-not-burn products are electronic devices that heat real tobacco to a high temperature — just below the point of combustion — to release a tobacco-flavoured nicotine aerosol. Unlike cigarettes, they don’t burn the tobacco, so there’s no smoke, just vapour. The most popular brand right now? IQOS, developed by Philip Morris International.
Vaping vs heat-not-burn: What’s the difference?
1. Ingredients
Vaping uses e-liquids that contain nicotine, propylene glycol, vegetable glycerin, and flavourings — no tobacco at all. HNB, on the other hand, uses actual tobacco sticks (often called HEETS or TEREA), which are heated inside the device.
2. Flavour and feel
HNB offers a more “authentic” tobacco taste, which some ex-smokers prefer. Vaping, by contrast, gives a massive flavour range — from mint to mango to cola — making it more appealing for those who want to move away from the cigarette experience entirely.
3. Smell and residue
Vapes typically leave no lingering smell or residue. HNB devices do produce a tobacco-like aroma — it’s not smoke, but it's not exactly invisible either. If discretion is your thing, vaping still wins.
Which is safer: heat-not-burn or vaping?
Let’s get this straight — neither is 100% risk-free. But both are considered less harmful than smoking by leading health agencies. Here’s what we know:
- Vaping is estimated by Public Health England to be at least 95% less harmful than smoking, mostly because it eliminates combustion and tar.
- Heat-not-burn products still involve real tobacco, meaning there are trace levels of harmful chemicals — but far fewer than in cigarettes.
So far, most UK experts still rank vaping as the safer option — especially when e-liquids are TPD-compliant and used correctly.
Popularity in the UK: Who’s using what?
Vaping is still king in the UK, with around 4.7 million adult users in 2024. Heat-not-burn is newer and growing fast, but its usage is still much lower, especially among younger adults.
Why the slower uptake for HNB?
- Cost – IQOS devices are more expensive up-front.
- Limited flavour variety – Tobacco-focused flavours only.
- More like smoking – Which can be a turn-off for those trying to fully quit the habit.
Which is better for quitting smoking?
It depends on your goal:
- If you want to quit smoking and nicotine entirely: Vaping offers more flexibility to reduce nicotine over time, even down to 0mg.
- If you still enjoy the tobacco experience but want fewer toxins: Heat-not-burn may feel more familiar and satisfying.

Final thoughts
Both heat-not-burn and vaping have a place in the UK's harm reduction landscape. But they serve slightly different audiences. If you want to wean off nicotine altogether, vaping offers more control and versatility. If you miss the ritual of smoking and aren’t ready to quit nicotine, HNB devices like IQOS might be your thing.
