Human Laboratory Study of the Effects of Nicotine Product Claims on Appeal, Perceptions, and Use Behavior

"Participants will be randomly assigned to conditions in a 3 (Nicotine Concentration: None on label, Low, High) x 3 (Nicotine Source Claim: None, Tobacco Free, Synthetic Nicotine) between-subjects design. We will stratify randomization by young adult susceptible non-users and adult tobacco users for balance across the conditions. Participants will view 16 oral nicotine pouch pack images in random order that correspond to the nicotine concentration and source claim condition they are randomized to. Within each condition, pack images will vary by 4 brands and 4 flavors per brand. While viewing the images, we will collect psychophysiological data including heart rate, galvanic skin response, and eye tracking."
