Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study assesses the acute effects of a standardized 20-minute vaping episode compared to a non-vaping control condition on ad libitum food intake during a 30-minute buffet meal, occurring approximately 45 minutes after the vaping episode

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Weight control is a common motive for cigarette smoking and nicotine has been shown to suppress appetite and increase resting metabolic rate, and also serves as a behavioral alternative to eating or a distraction from hunger or food craving. Data on the acute effect of e-cigarette use ('vaping') on ad libitum food intake are non-existent. Given that many e-cigarette users report vaping for weight control and that certain e-cigarettes are being actively marketed for weight management and/or suppression of food cravings, addressing this research gap is of the utmost importance.

Intervention Model

CROSSOVER

This study consists of a baseline assessment which is followed by two within-subject, laboratory conditions that differ by the product used: 1) JUUL e-cigarette with a 5% nicotine pod, 2) no active e-cigarette use (uncharged JUUL with empty pod). The condition orders (i.e., 1 then 2, or 2 then 1) will be randomly ordered and assigned following enrollment. During the vaping condition, participants will be asked to take 20 e-cigarette puffs over 20 minutes before consuming an ad libitum buffet meal. During the alternative control condition, participants will have access to an uncharged JUUL with an empty pod for 20 minutes (instead of vaping) before consuming an ad libitum buffet meal.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Vaping to Control Group

Participants in this arm will undergo the vaping condition during the first visit and the control condition during the second visit.

Group Type EXPERIMENTAL

Vaping condition

Intervention Type OTHER

Participants will be asked to use a JUUL device to vape 20 puffs over 20 minutes. Participants will use JUUL pods with \~5% nicotine by weight. The anticipated amount of nicotine that will be absorbed with 20 puffs is approximately 1.6 mg, which is equal to approximately 1.5 cigarettes.

Control condition

Intervention Type OTHER

Participants will have access to an uncharged JUUL device with an empty pod for 20 minutes.

Control to Vaping Group

Participants in this arm will undergo the control condition during the first visit and the vaping condition during the second visit.

Group Type EXPERIMENTAL

Vaping condition

Intervention Type OTHER

Participants will be asked to use a JUUL device to vape 20 puffs over 20 minutes. Participants will use JUUL pods with \~5% nicotine by weight. The anticipated amount of nicotine that will be absorbed with 20 puffs is approximately 1.6 mg, which is equal to approximately 1.5 cigarettes.

Control condition

Intervention Type OTHER

Participants will have access to an uncharged JUUL device with an empty pod for 20 minutes.
