Study 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).
Primary Outcome
Smoking behaviors were assessed using video-scored measures of smoking topography (i.e., puffing behavior), including number of puffs taken, total puffing duration, and total interpuff interval (time between puffs). Briefly, research staff used a digital timestamp feature in an open-source video editing software to estimate start and end times for individual puffs based on various physical cues (e.g., inhaling, glowing cigarette tip), prioritizing overall puffing behaviors (e.g., multiple occurr
