Vanilla and coconut scents may disrupt cigarette cravings, brain study hints

NCT ID NCT04902469

First seen Jul 02, 2026 · Last updated Jul 02, 2026

Summary

This study investigates whether sniffing pleasant odors like vanilla, coconut, or chocolate can reduce cigarette cravings. Researchers will use brain scans (fMRI) and behavioral tests to see how these smells affect craving-related brain activity in daily and nondaily smokers aged 18-49. Participants are randomly assigned to receive either a pleasant odor or a neutral blank odor during craving triggers. The goal is to understand if pleasant scents can disrupt the brain's craving state and lower the urge to smoke.
