Cue Reactivity Effects of Heated Tobacco Product Use in Current, Former, and Never Smokers in the United States.

Non-combustible nicotine delivery systems are known cues for cigarette smoking and e-cigarette vaping, and this study examined whether relatively novel heated tobacco products (HTPs) may also act as a smoking or vaping cue in adults across varied smoking backgrounds. Results showed that passive exposure to HTP use increased desire for both a cigarette and an e-cigarette in current smokers and also increased desire for an e-cigarette in former and non-smokers. Thus given its similarity to smoking and vaping, HTP use may affect passive observers and could play a role in perpetuating dual use of cigarettes and vape products.
