The Abuse Liability of a Novel Heated Tobacco Product (IQOS) and Its Feasibility as a Menthol Cigarette Substitute

Participants are first instructed to smoke their usual brand of menthol cigarettes normally for the next 7 days and avoid using any other tobacco products. After this baseline week, participants are randomized to 1 of 2 HTP flavor conditions (tobacco-flavored HeatSticks or Fresh Menthol-flavored HeatSticks), with equal probability and provided with a supply of their condition specific HTP and asked to use it in place of their usual menthol cigarettes for the next week. Participants use their own brand menthol cigarettes and assigned HTP both at home (naturalistic use) and in the clinical laboratory (two visits/week).
