Impact Of IQOS Non-Cigarette Tobacco Product On Reinforcement Value and Use In Current Smokers

Detailed Summary

A novel type of non-cigarette tobacco product was recently approved for sale in the US, the heated tobacco product (HTP) IQOS. IQOS may be less harmful than cigarettes, and there are some reports that it may produce more rewarding subjective effects compared to e-cigarettes. The approval of IQOS provides a unique opportunity to gather preliminary data surrounding IQOS. The goal of this pilot study is to assess the subjective effects and relative reinforcement value of IQOS, including its downstream effects on cigarette smoking. Current smokers will complete a one-week baseline period where they smoke as normal before attending an in-person lab visit. During the in-person lab visit, participants (n=10) will sample a traditional cigarette and a novel IQOS tobacco product. Participants will answer questionnaires about each product they sample and then complete a preference assessment in which they choose between the IQOS and their own cigarette. Finally, participants will take home a tobacco product they sampled to use ad libitum (1-week sampling). During the at-home baseline and sampling weeks, participants will complete electronic daily diaries cataloging their tobacco use. Biomarkers (i.e., expired carbon monoxide, cotinine) will corroborate self-reported indices of use.
