Sponsor's own description
The goal of this clinical trial is to determine whether blockers of perception of key odorants in cigarette smoke have any utility in smoking cessation. The main question it aims to answer is: • Can odor blockers be used to suppress perception of the intensity of cigarette smoke in ways that reduce the ability of the odor of cigarette smoke to increase the urge to smoke. Participants will be asked to smell up to 20 odor samples per session and report on odor pleasantness and desire to smoke.
