Brief summary

This study aims to better understand how the availability of electronic nicotine delivery system (aka electronic cigarettes) flavors (e.g., menthol, tobacco) impacts tobacco use behaviors, toxicant exposure, and abuse liability among African American menthol smokers.

Detailed description

Black/African American (AA) menthol smokers are disproportionately harmed by tobacco products and could experience significant health benefits from increased availability of well-regulated electronic nicotine delivery systems (ENDS). The current study will evaluate whether ENDS flavor availability affects measures of tobacco use, biomarkers of cigarette/ENDS exposure, and addiction among AA menthol smokers by performing a 3-arm, 6-week clinical trial of ENDS provision with follow-up to 30 days. Results of this work will help FDA make predictions about the impact of moving from the current regulatory market were menthol/tobacco flavored ENDS cartridges are available, to one where only tobacco or unflavored cartridges are available, in order to maximize health-promoting effects and minimize unintended consequences among AA menthol smokers.

Interventions

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 3 ENDS flavor conditions, all contain 5% nicotine (Mentol+Tobacco, Tobacco, Unflavored) with equal probability and provided with a supply of their condition specific ENDS and asked to use it in place of their usual menthol cigarettes for the next 6 weeks.

Design outcomes

Primary

MeasureTime frameDescription
Average Daily Cigarette UseRandomization and Week 6Number of cigarettes used in the past day, collected via daily text survey, averaged over the past week
Carbon Monoxide ExposureRandomization and Week 6A biomarker of combusted cigarette use collected from exhaled breath.
Willingness to Substitute From Cigarettes to ENDSWeek 6CP-DPT involves participants making two hypothetical choices at once, for a series of price scenarios involving their own brand cigarettes and condition-specific ENDS. For example, participants are asked how many puffs of their Own Brand Cigarette AND how many puffs of a their conditions-specific ENDS they would purchase if each Own Brand Cigarette puff cost $0.00 (i.e., free) and each ENDS puff cost $0.10. The outcome of the task is the willingness to pay in USD for each ENDS puff.
