What Is Heated Tobacco?
Devices that heat real tobacco rather than burning it. Likely less harmful than smoking, but contains tobacco and nicotine and is not risk free.
Heated tobacco is a category of product that often gets confused with vaping, so it helps to know what it actually is. In short, heated tobacco products use a device to heat real tobacco rather than burn it, producing an aerosol the user inhales. Because it heats rather than burns, it is likely less harmful than smoking, but it still contains tobacco and nicotine and is not risk free. This guide explains, alongside our guide on whether heated tobacco is safer than smoking.
Quick answer
Heated tobacco products heat real tobacco rather than burning it, using a device, to produce an aerosol the user inhales. Because there is no burning, they are likely less harmful than smoking, but they still contain tobacco and nicotine, are not risk free, and are generally considered more harmful than vaping, which contains no tobacco.
What heated tobacco is
Heated tobacco products, sometimes called heat not burn, use an electronic device to heat specially made tobacco sticks or units to a high temperature, but without setting them alight. This produces an aerosol containing nicotine that the user inhales. The key difference from cigarettes is that the tobacco is heated, not burned, while the key difference from vaping is that it contains real tobacco.

How it compares
Because much of smoking''s harm comes from burning tobacco, heating instead of burning reduces some harmful chemicals, which is why heated tobacco is likely less harmful than smoking. However, it still contains tobacco and nicotine, still exposes the user to harmful substances, and is generally considered more harmful than vaping, which contains no tobacco. The evidence on heated tobacco is also less complete than for vaping.
Heated tobacco heats real tobacco rather than burning it, producing an aerosol. It is likely less harmful than smoking, but contains tobacco and nicotine, is not risk free, and is generally more harmful than vaping.

Where it sits between smoking and vaping
Heated tobacco sits, in broad harm terms, between smoking and vaping. It is likely less harmful than cigarettes, because it does not burn the tobacco, but it is generally considered more harmful than vaping, because it still contains tobacco. So it is not a safe option, simply a different point on the spectrum, with the evidence still developing.
For a smoker, the healthiest step remains stopping tobacco and nicotine altogether, and for those who would otherwise smoke, less harmful alternatives exist. Heated tobacco is one such product, but it is not as low risk as vaping and not risk free.
Broad harm spectrum
| Option | Position |
|---|---|
| Smoking | Highest harm |
| Heated tobacco | Lower than smoking |
| Vaping | Lower than heated tobacco |
| Nothing | Best for health |
| Note | Evidence still developing |

Heated tobacco versus vaping
The most common confusion is between heated tobacco and vaping, and the difference is simple but important. Heated tobacco heats real tobacco leaf, so it contains tobacco and produces a tobacco aerosol. Vaping heats a tobacco free e liquid, so it contains no tobacco at all. That is why vaping is generally considered lower risk than heated tobacco.
Both are less harmful than smoking for someone who would otherwise smoke, but they are not the same product, and they are not interchangeable in harm terms. For anyone using tobacco or nicotine, stopping altogether remains the healthiest goal.

|---|---|---|

| Nicotine | Yes | Usually |
| Relative harm | Higher than vaping | Lower |
| Versus smoking | Likely less harmful | Substantially less |

A quick word on safety and the law
Vaping and nicotine products are intended for adult smokers and existing vapers as a less harmful alternative to cigarettes. They contain nicotine unless stated otherwise, which is addictive, and they are not suitable for non smokers, pregnant women or anyone under 18. By law you must be 18 or over to buy vaping products in the UK, and we age verify every order. If you want to stop using nicotine altogether, your local stop smoking service offers free, tailored support.
UK public health bodies advise that vaping is substantially less harmful than smoking, but it is not risk free, and if you do not smoke the advice is not to start.
