About this study
This study assess the ways in which e-cigarette product characteristics, such as flavors and nicotine salts, impact user experience to inform potential regulations.
Read the detailed description
There are three primary objectives to the study: (1) Determine which dimensions of e-cigarette product diversity differentially affect product appeal in the overall population of tobacco product users as well as affect product appeal across young adult e-cigarette users and middle-age/older adult smokers; (2) Determine which dimensions of e-cigarette product diversity differentially affect product appeal in the overall population of tobacco product users as well as affect abuse liability in young adult e-cigarette users and the ability to resist smoking in adult smokers; (3) Determine the affect of product characteristics on e-cigarette nicotine delivery profile.

Participants will self-administer experimenter-provided e-cigarettes
| Study group | Role | What they receive |
|---|---|---|
| E-Liquid 1 | Experimental | Participants will self-administer an assigned e-liquid. Receives: Other: E-cigarette |
| E-Liquid 2 | Experimental | Participants will self-administer an assigned e-liquid. Receives: Other: E-cigarette |

What is being measured
The primary outcome is the main question the study is designed to answer.
Subjective Appeal
This self-report measures of subjective product appeal will be completed following e-cigarette self-administration. Scores can range from 0 to 100 for the appeal rating, with lower scores representing lower levels of appeal and higher scores representing higher levels of appeal.
Measured: 1 hour
Sensory Attributes
This self-report measures of product sensory attributes will be completed following e-cigarette self-administration. Scores can range from 0 to 100 for the sensory attribute rating, with lower scores representing lower levels of liking the sensory attribute and higher scores representing greater liking of the sensory attribute.
Measured: 1 hour
Vaping Delay
Minutes delayed before purchasing time to vape an e-liquid.
Measured: 1 hour
