Acute Effects of Oral Nicotine Pouches

Официальное название

The Acute Effects of Oral Nicotine Pouches Among Infrequent and Frequent Nicotine/Tobacco Users

Обзор

The present human laboratory study will recruit cigarette smokers (n=60) and adult infrequent nicotine users (n=60) to complete two counterbalanced lab sessions in which the participants use nicotine pouches under controlled conditions. The investigators are recruiting both frequent and infrequent nicotine users because FDA regulates tobacco products based on a public health standard, meaning FDA must consider the impact a regulation may have on the population as a whole (e.g., people who use and do not use tobacco products currently).

Подробное описание

This study will be conducted at the Johns Hopkins Behavioral Pharmacology Research unit (BPRU). Participants will complete a screening visit, and, if eligible, will then complete 2 outpatient experimental sessions (separated by at least 48 hours). The study will use a mixed between/within-subjects crossover design. The between-subjects component is because there are two groups of participants (60 cigarette smokers, 60 infrequent nicotine users) and the within-subjects component is because participants complete all experimental sessions (thus, serving as the participant's own control). Smokers will be instructed to abstain from all tobacco 12 hours prior to each session so that the participants begin study sessions in a state of nicotine/tobacco withdrawal. Sessions will be completed in a counterbalanced order to reduce order effects. During each experimental session, a battery of assessments including subjective questionnaires (abuse liability, nicotine-related effects, withdrawal suppression), cognitive performance, blood collection for pharmacokinetic analysis (this will be optional), vital signs, and pouch use (or topography) will be conducted
