Comparative Acceptability of Tobacco and Menthol Flavored E-cigarettes

University of Kansas Medical Center52 enrolled

Overview

The study is a randomized crossover trial. Current menthol smokers will complete a session with each flavor of an electronic cigarette: menthol and tobacco. The objective of this survey is to assess for flavor preference.

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.

Outcomes

Primary Outcomes

Questionnaire Scale "Intentions for Future Use"

Using the questionnaire scale "Intentions for Future Use" How much each participant intends to use the products in the future. Scale: "Think about the product you just used. If this was the only flavor available, how likely would you be to try this flavor again? 1. Extremely unlikely 2. Unlikely 3. Neutral 4. Likely 5. Extremely likely The range of observed responses from participants for both groups was 1-5. Not all participants completed all study measures so the number of respondents is lower than enrolled.

Time frame: during the intervention

Secondary Outcomes

Questionnaire Scale "Subjective Vaping Experience"

Please indicate how you are feeling right now on a scale from 0 to 100 where 0 is not at all and 100 is extremely. How pleasant would the e-cigarette be to use right now? The observed range of responses from participants for both arms was 0 to 100. Not all participants completed all study measures so the number of respondents is lower than enrolled.

Time frame: during the intervention

Questionnaire Scale "Perceptions of Flavor"

On a scale from 0 to 100 where 0 is not at all and 100 is extremely, to what extent did you like the flavor you just used? The observed range of responses from participants in both arms was from 0 to 100. Not all participants completed all study measures so the number of respondents is lower than enrolled.

Time frame: during the intervention

Questionnaire Scale "Product Demand"

On a scale from 0 to 100 where 0 is not at all and 100 is extremely, how willing would you be to use the flavor you just used again in the future?
