What this trial studies

This study investigates how synthetic cooling additives, such as WS-3 and WS-23, influence perceptions of e-cigarettes, user behavior, and exposure to toxicants. Participants aged 21-29 who are current exclusive e-cigarette users will attend four sessions where they will use one of four randomly assigned flavored e-cigarettes. The study aims to assess the abuse liability of these e-liquids, analyze puffing behavior, and measure exposure to harmful constituents. Surveys and biosample collections will be conducted throughout the sessions to gather comprehensive data.

Who should consider this trial

Good fit: Ideal candidates are individuals aged 21-29 who are current exclusive e-cigarette users.

Not a fit: Patients who are not current e-cigarette users or have significant psychiatric conditions may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide insights into safer e-cigarette formulations and inform public health strategies.

How similar studies have performed: While studies on e-cigarettes exist, the specific focus on synthetic cooling agents is relatively novel and has not been extensively tested.
