Comparative Acceptability of Tobacco and Menthol Flavored E-cigarettes

Participants who report typically smoking menthol cigarettes will be invited to complete a session. Participants will undergo overnight tobacco/nicotine abstinence before the visit (eCO<12ppm). Participants will then be randomized 1:1 to e-cigarette flavor order (tobacco e-cigarette, menthol e-cigarette). They will complete a 30-minute ad libitum session with the first product, based on randomization, followed by a 1.5 hour standard washout period, followed by a 30-minute ad libitum vaping session with the second product. Throughout each session, puff topography will be measured via a pressure sensor attached to the e-cigarette device. Participants will complete self-report measures of smoking urges and withdrawal symptoms pre- and post-vaping session. In addition, they will complete measures of subjective vaping experience, perceptions of flavor, product demand, and intentions for future use.
