Abstract: Introduction : Research from Philip Morris International’s science division on its Heat-not-Burn product IQOS TM focused on its chemical, toxicological, clinical, and behavioral aspects. Independent research on the experiences and behavioral aspects of using IQOS TM , and how it compares to e-cigarettes, is largely lacking. The current randomized, cross-over behavioral trial tried to bridge the latter gaps. Methods : Participants ( n = 30) came to the lab on three consecutive days after being overnight smoking abstinent. During each session, participants used one of three products (cigarette, e-cigarette, or IQOS TM ) for five minutes. Exhaled CO (eCO) measurements and questionnaires were repeatedly administered throughout the session. Results : Smoking a cigarette for five minutes resulted in a significant increase of eCO, whereas using an IQOS TM resulted in a small but reliable increase (0.3 ppm). Vaping did not affect eCO. Cigarette craving reduced significantly after product use, with the decline being stronger for smoking than for e-cigarettes or IQOS TM . Withdrawal symptoms declined immediately after smoking or using IQOS TM , and with some delay after vaping. IQOS TM scored higher in terms of subjective reward/satisfaction and was slightly preferred to the e-cigarette. Discussion : Short-term use of IQOS TM has a minimal impact on eCO, is equally effective in reducing cigarette craving and withdrawal symptoms as an e-cigarette, and is slightly preferred.
