Is this trial a fit for you?

Likely a good fit

Adults 21–65 who smoke daily, are willing to use ENDS, own a smartphone, and can read and sign consent.

Probably not a fit

Participants who do not quit smoking may not experience a direct benefit from this intervention.

What this trial studies

This is a multi-site, open-label, single-arm trial that looks at end-of-study smoking abstinence in healthy adult cigarette smokers who are provided an electronic nicotine delivery system with multiple flavor options over 13 weeks. Results will be compared to a prior randomized trial that used a single flavor. Participants will use a study app to report surveys and may receive a study-provided phone for study activities. The study is sponsored by RAI Services Company and conducted at three U.S. sites.

Why it matters

Potential benefit: If successful, participants may experience higher chances of quitting smoking with the help of flavored ENDS.

How similar studies have gone: Previous research with ENDS and flavor options has shown mixed results; this trial builds on prior work by adding flavor choice in a real-world setting.
