Official title
Effects of Filter Ventilation on Sensory Response, Smoking Topography, and Inhalation (COMET 2 2.1)
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
This trial examines the effects of filter ventilation on sensory response, smoking topography, and inhalation in current every day cigarette smokers. The physical design features of cigarettes directly impact their appeal by influencing cognitive and sensory perceptions. The introduction of a now common design feature, filter ventilation, has led to greater public harm than benefit because of the potential for greater toxicity while enhancing product appeal among smokers. Ventilated cigarettes dilute smoke, which promotes perceptions of ?smoothness? and therefore lower health risk, contributing to the overall appeal of these products. The purpose of this study is to assess whether removing ventilation from cigarette filters lowers cigarette product appeal among smokers.
