Is IQOS safer than vaping?

The consensus is that IQOS lowers toxicant exposure vs smoking, but it still delivers tobacco-specific compounds that vaping does not. Compared with a vape, IQOS is a step towards cigarettes, not away from them.

Does IQOS contain tobacco?

Yes. IQOS uses HeatSticks (real processed tobacco) heated by an electronic holder. Vapes use e-liquid with no tobacco.

Can IQOS help me quit vaping?

No. Switching from vaping to IQOS keeps you dependent on nicotine and adds tobacco exposure. Use approved cessation aids (NRT, varenicline, bupropion, cytisine) if the goal is to quit.

Is IQOS sold in the US?

IQOS was previously sold in a limited US pilot, then withdrawn after patent litigation. As of 2026 availability is limited; it remains widely sold in Japan and parts of Europe.

Vaping vs IQOS: What Heat-Not-Burn Actually Is, and How It Compares

IQOS heats tobacco instead of burning it. Here is how it compares with vaping on nicotine delivery, chemistry, respiratory exposure, and whether it is a useful switch from either cigarettes or vapes.

The short answer

IQOS is a heat-not-burn tobacco product: real tobacco heated to about 350 C rather than combusted. It delivers nicotine and tobacco-specific compounds without smoke, but it is not the same as vaping, which uses an e-liquid and no tobacco. Both are less harmful than smoking; neither has long-term outcome data. IQOS is more expensive and less flexible than vaping, and it is not an approved cessation aid.

Key takeaways

IQOS heats tobacco to about 350 C; cigarettes burn tobacco at 800 C.
It emits an aerosol with fewer toxicants than smoke, but more than vape aerosol.
Nicotine delivery is closer to a cigarette than to a Juul.
Neither IQOS nor vaping is an approved cessation aid.
For a vaper, switching to IQOS reintroduces tobacco exposure.

IQOS ("I Quit Ordinary Smoking", a marketing name) is a heat-not-burn tobacco product from Philip Morris. It heats tobacco sticks instead of burning them. It is a real category and gets confused with vaping constantly.

What is different from vaping

What is heated. Tobacco (IQOS) vs e-liquid (vape).
Temperature. ~350 C (IQOS) vs ~200 C (vape coil).
Emissions. IQOS produces an aerosol with tobacco-specific nitrosamines and other tobacco compounds; vape aerosol contains none of those.
Nicotine curve. IQOS is closer to a cigarette than a Juul: quick delivery, familiar hit.

Risk framing

Both products avoid combustion, which is where most cigarette harm comes from. But they are not the same:

Vaping removes tobacco entirely; risks are aerosol/flavouring-related and largely unknown long-term.
IQOS keeps tobacco in the picture; some tobacco-specific harms carry over, just at lower levels.

For a smoker, either is a substantial step down. For a vaper, IQOS is a lateral or worse move because it reintroduces tobacco.

Cost and flexibility

IQOS requires a proprietary device (~$70-100) and single-use HeatSticks priced close to cigarettes. Vapes range from disposables ($8-15) to refillables ($20-30 device + $10-15 pods/liquid). See disposable vs refillable and the true cost of vaping.

Cessation

Neither is an approved cessation aid. If quitting is the goal, use NRT, varenicline/Chantix, bupropion, or a quitline.
