Cigarettes produce tar – IQOS doesn’t

Tar is the residue from smoke after a cigarette is burned. IQOS does not produce tar because it heats tobacco instead of burning it. It generates an aerosol residue that is fundamentally different from tar and consists of significantly lower levels of harmful chemicals.*

Switching completely to IQOS is less harmful than continuing to smoke.**
Important information: The absence of tar does not mean that IQOS is risk free. IQOS provides nicotine which is addictive.

*Average reductions in levels of a range of harmful chemicals (excluding nicotine) compared to cigarette smoke.

***Source: Based on the totality of evidence available for IQOS in comparison with continuing to smoke.

IQOS emits less harmful chemicals than cigarettes

Cigarettes burn tobacco, which produces high amounts of carbon monoxide. IQOS doesn’t burn tobacco, producing on average 98% less carbon monoxide (CO) and significantly lower levels of other harmful chemicals compared to cigarettes.*
Important information: This does not mean a 98% reduction in risk. IQOS is not risk-free, and delivers nicotine which is addictive.
**Source: We measured the levels of certain harmful chemicals prioritised for reporting by renowned public health organisations, and these are reduced on average by 95% compared to the smoke of a cigarette (nicotine excluded).
