⚖️ "Fewer harmful substances" and "safe" are not the same. The biggest misunderstanding about IQOS
"Fewer harmful substances" and "safe" are not the same. The biggest misunderstanding about IQOS.
Certain phrases come up a lot when people talk about IQOS.
"Fewer harmful substances than cigarettes."
"No smoke."
"It doesn't burn."
"The FDA approved it."
At a glance, these sound convincing. But there's a big trap here.
**Reduced exposure and how much your disease risk drops are not the same thing.**
The FDA authorized only "reduced exposure"
In 2020, the US FDA authorized "reduced exposure" marketing for IQOS — that switching completely from cigarettes "significantly reduces your body's exposure to certain harmful or potentially harmful chemicals." But this does not mean it approved it as "safe," "harmless," or "certain to lower disease risk." The FDA's decision permitted a reduced-exposure claim for full switching; it did not permit a claim that risk disappears.
This distinction needs to be conveyed carefully to readers.
"Half" isn't "safe"
Say there's a food with the salt cut in half. The salt may be lower. But eating that food in large amounts every day isn't necessarily healthy. Likewise, even a product with less of some harmful substances requires separate verification of how actual disease risk changes with long-term use.
A systematic review and meta-analysis of heated tobacco published in BMJ Tobacco Control concludes that longer-term, high-quality research independent of the tobacco industry is needed on how much heated tobacco changes health effects. In particular, existing studies are said to be limited by being short-term, small-scale, and industry-funded.
What we can say now
So what can be said about IQOS at this point is:
It's not the same as cigarettes.
Exposure may be reduced.
But it can't be called safe.
Long-term disease risk still isn't well understood.
And the healthiest choice is to use no tobacco product at all.
Quit-smoking media needs this framing.
Because smokers often convert "a little better" into "I'm fine now."
There's no need to blame people who switched from cigarettes to IQOS. Behind it there's surely health anxiety, consideration for family, and a wish to reduce the smell. But making that the finish line means missing the chance to quit.
IQOS is "switching," not "quitting"
The message to send is this:
IQOS isn't "quitting" — it's "switching."
If you've switched, the next step is "preparing to stop completely."
Rather than hunting for harm that seems a bit lower than cigarettes, aim for a life not bound by nicotine. Not losing that perspective is essential for quit-smoking columns in the IQOS era.
