Heated tobacco - a new review looks at the risks and benefits
Switching from cigarettes to heated tobacco reduces exposure to harmful chemicals but more evidence is needed on how it affects our health, say PhD candidate Harry Tattan-Birch, Professor Jamie Brown (both UCL Epidemiology & Health) and Professor Jamie Hartmann-Boy.Get more news about

Heated tobacco products are designed to heat tobacco without burning it or producing smoke. The popularity of these products soared in Japan after the release of an electronic device called IQOS in 2016. Heated tobacco products are now available in many countries, but questions remained about their effect on cigarette smoking and health, so we set out to review the evidence.
Our new review covers data from 11 studies with over 2,600 people. The headline finding is that people who switched from cigarettes to heated tobacco had lower levels of exposure to harmful chemicals than those who kept smoking, but higher levels of these toxins than those who stopped using tobacco altogether.
This lower exposure was found across a number of harmful substances linked to cancers, heart disease and respiratory problems. This means it is possible that switching from cigarettes to heated tobacco could reduce the odds of developing these diseases, but we don’t have enough data yet to be sure. The studies were all of short duration, and it typically takes a while for people to develop tobacco-related diseases.
That said, the evidence so far is consistent with how uniquely dangerous smoking is. We know that most of the harmful effects of cigarettes — which kill half of all regular smokers — come from inhaling toxic chemicals made by burning tobacco. As heated tobacco products are designed to avoid burning tobacco, we’d expect them to pose a lower risk.
Heated tobacco products could benefit public health if they reduce risk and help people stop smoking normal cigarettes, without attracting people who would otherwise avoid tobacco entirely.
We didn’t find any studies looking at whether giving smokers heated tobacco products helped them stop smoking. But we found two Japanese studies looking at how cigarette sales changed after IQOS entered the market. Both found that falls in cigarette sales sped up after the IQOS launch, suggesting that heated tobacco products might replace rather than complement cigarettes.
On the other hand, it is possible that sales of cigarettes fell because most people cut down without stopping altogether. The greatest improvements in health come from stopping smoking altogether rather than smoking fewer cigarettes.
E-cigarettes, or vapes, are another group of nicotine products that have become very popular in recent years. Heated tobacco products heat tobacco leaf, whereas e-cigarettes heat a liquid, typically containing nicotine. There are large differences in the science and regulation of these products. E-cigarettes have been on the market for longer than heated tobacco, so we have more evidence about their benefits and harms.
Unlike heated tobacco, e-cigarettes have been shown to help people stop smoking normal cigarettes. In the not-too-distant future, the UK may even offer e-cigarettes to those who wish to quit smoking, as long as the products pass the necessary regulatory hurdles.
