Outcome Measures

Primary Outcomes (1)

  • Energy Intake

    Energy intake in kilocalories (kcal) during the ad libitum buffet meal will be measured via directly weighed food provision and waste (food/energy intake is calculated by difference).

    intake was assessed over a 30 minute meal

Secondary Outcomes (14)

  • Dietary Added Sugar Intake

    intake was assessed over a 30 minute meal

  • Dietary Sugar Intake

Interventions

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 to Vaping GroupVaping to Control Group

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

Intervention Model
CROSSOVER
Model Details: 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.
