Nicotine and Cannabis Vape Labeling Experiment - Spring 2025

N/AEnrolling By InvitationNCT06919276

University of Southern California3,900 enrolled

Overview

This study assesses how the ways in which nicotine and cannabis vaping devices are labeled impact use susceptibility, anticipated effects, and health harm.

The primary objectives of the study: (1) Determine whether different device labels with the contained substance (nicotine or cannabis) affect adolescent use susceptibility, anticipated effects or impairment, and perceived health harms; (2) Determine whether device color/product flavor differentially impact the study outcomes.

Vaping Device LabelingOTHER

Participants will view one vape image (experimental stimulus) and are randomized to a label presented and the color/flavor of the vaping device presented. The label conditions are: 1. plain (i.e., no labeling on device) 2. "contains THC" 3. "contains 80% THC" 4. "contains 80% THC - HIGH POTENCY" 5. "contains nicotine" 6. "contains 5% nicotine" 7. "contains 5% nicotine - HIGH STRENGTH" The color/flavor conditions are: mint/mint, white/original, blue/blueberry.

Outcomes

Primary Outcomes

Use Intention Susceptibility

This 3-item self-report measure assesses participant interest in trying the vaping device in the future. A 4-level Likert scale is used: definitely not, probably not, probably yes, definitely yes.

Time frame: 5 minutes

Perceived Health Harms

This 2-item self-report measure assesses participant perception of health harms and risks associated with using the vaping product. A 4-level Likert scale is used: definitely not, probably not, probably yes, definitely yes.

Time frame: 5 minutes

Anticipated Subjective Effects

This 9-item self-report measure assesses anticipated subjective effects from using the vaping device. Participants will select all that apply.

Time frame: 5 minutes

Anticipated Impairment/Enhancement

This 4-item self-report measure assesses participant anticipated enhancement or impairment effects on completing different activities due to using the vaping product. A 5-level Likert scale is used: definitely make it harder, probably make it harder, no effect, probably make it easier, definitely make it easier.

Time frame: 5 minutes
