Acute Effects of Cigarette Packaging and Charcoal Filtration on Perceptions, Use Behaviors, and Harm Exposure

Abramson Cancer Center at Penn Medicine·interventional·Posted Dec 14, 2021·Updated Nov 7, 2024

In Brief

A clinical study evaluating Charcoal-filtered cigarette and Non-charcoal filtered cigarette for Smoking Behaviors. Completed, enrolled 42 participants across 1 site.

Detailed Summary

This single laboratory session pilot study will examine the acute effects of cigarette filter type and packaging on initial product perceptions, use, and exposure. Forty adult daily smokers will be randomized to smoke two study-supplied commercially-available cigarettes interspersed by 45 minutes, completing pre- and post-cigarette carbon monoxide and questionnaire measures. We will use a 2 x 2 mixed factorial design to manipulate cigarette filter type (within-subject: charcoal vs. non-charcoal) and packaging (between-subject: light vs. dark).
