What this research studies

You would use a smartphone app that pairs an established quitting program with brief, intentional sniffing of selected scents when cravings hit. The team will refine how and when the scents are delivered and pilot the combined approach in real-world settings. The work builds on lab and small pilot studies that found scent inhalation can reduce cigarette craving. If you join, you may be asked to use the Android app, follow prompts to sniff provided scents, and complete follow-up checks while trying to quit.

Who could benefit from this research

Good fit: Adults (21+) who currently smoke cigarettes and want help quitting and who can use a smartphone (likely Android) are ideal candidates.

Not a fit: People who do not smoke, are not trying to quit, have no sense of smell, or lack smartphone access are unlikely to benefit from this approach.

Why it matters

Potential benefit: If it works, this could give smokers an easy, low-cost tool to reduce cravings and improve chances of quitting.

How similar studies have performed: Early laboratory and pilot studies suggest scent inhalation can cut craving, but combining it with a phone-based quit program is a new, not-yet-proven approach.
