What this trial studies

This clinical trial investigates the effectiveness of odor blockers in reducing the perception of cigarette smoke odors to aid smoking cessation. Participants will inhale various odor samples, including cigarette smoke and odor blockers, while reporting their experiences regarding odor pleasantness and their desire to smoke. The study aims to determine if blocking the smell of cigarette smoke can decrease the urge to smoke. Each participant will undergo multiple sessions with randomized odor presentations to assess their responses accurately.

Who should consider this trial

Good fit: Ideal candidates for this study are current smokers who are willing to participate in odor perception assessments.

Not a fit: Patients who are non-smokers or have self-reported difficulties in smelling or tasting will not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could provide a novel method for smokers to reduce cravings and aid in quitting smoking.

How similar studies have performed: While the use of odor blockers in smoking cessation is a novel approach, similar studies exploring sensory perception and smoking behaviors have shown promise.
