'It's not what you'd term normal smoking': a qualitative exploration of language used to describe heated tobacco product use and associated user identity.

People who use or have used IQOS (a brand of heated tobacco product) are ambiguous about IQOS terminology. Participants in this study commonly referred to IQOS use as smoking for lack of a more suitable term, but also resisted being labelled as smokers, a choice that may influence smoking cessation. Clear terminology must be used in surveys and by healthcare professionals when asking about cigarette smoking and e-cigarette and heated tobacco product use.
