简要总结
This clinical trial evaluates the impact of synthetic cooling agents in combustible cigarettes on smoking perceptions and use. Menthol, a natural chemical, is a cooling agent that increases nicotine dependence among smokers. Menthol cigarettes largely contribute to the huge burden that smoking puts on public health. Approximately 43% of adult smokers smoke menthol cigarettes. Regulatory agencies have begun a ban on menthol. In response to the ban, the tobacco industry has introduced synthetic cooling agents as a flavorless replacement to provide the same cooling effects as menthol. Information gained from this trial may help researchers determine how the addition of synthetic cooling agents changes the appeal, abuse liability potential, and respiratory toxicity profile of combustible cigarettes.
详细描述
PRIMARY OBJECTIVES:
I. Assess the content of synthetic cooling agents in newly introduced cooling agent non-menthol, menthol, and traditional non-menthol cigarettes.
II. Assess the subjective effects and abuse liability of cooling agent non-menthol cigarettes.
EXPLORATORY OBJECTIVE:
I. Examine acute changes to pulmonary health associated with cooling agent cigarette use.

结局指标
主要结局
Impact of Cooling Effects on Demand via the Forced Choice Task
时间窗: Up to end of study intervention, up to 3 weeks
At each study visit, after the participant has smoked the study cigarette, the participant must choose between smoking the study cigarette again, or smoking one of their own, usual brand cigarettes. Within each arm, the proportion of participants who opt to continue smoking the study cigarette will be reported. This will measure if demand for the study cigarettes is great enough to overcome the desire for the participant's own preferred cigarettes.
Cigarette Appeal
时间窗: Up to end of study intervention, up to 3 weeks
Participants will complete the Appeal and Sensory Quality questionnaire after smoking each study cigarette. This questionnaire will ask participants to rate each study cigarette for appeal characteristics such as liking, willingness to use again, flavor intensity, pleasantness of taste, etc. on a scale of 0 (not at all)-100(extremely).
Cigarette Chemical Contents
时间窗: Up to end of study, estimated 1 year
Tobacco samples from all three study cigarette types (menthol, non-menthol, synthetic cooling agent) will be extracted with isopropanol containing carvacrol. Nicotine, menthol, WS-3, WS-5, WS-12, and WS-23 amounts (mass) present in the different cigarettes will be quantified using gas chromatography mass spectrometry.
Abuse Liability via Puff Topography
时间窗: Up to end of study intervention, up to 3 weeks
Will be measured with a topography device that records frequency, duration, and flow rate of cigarette puffs. These measures are combined to inform overall cigarette puff behavior. Greater frequency, duration, and flow rate of cigarette puffs suggest greater abuse liability.
