Clinical Trial Summary

This study evaluates how synthetic cooling additives like WS-3 and WS-23 impact e-cigarette perceptions, use behavior, and toxicant exposure.

Description:

PRIMARY OBJECTIVES: I. Assess the abuse liability of e-liquids with and without the presence of synthetic cooling agents. II. Determine the impact of synthetic cooling agents and flavor on EC puffing behavior (topography). III. Determine the exposure ranges (harmful and potentially harmful constituents [HPHCs], other toxicants) from vaping e-liquids with and without the presence of synthetic cooling agents. OUTLINE: Participants attend 4 sessions where they receive 1 of 4 randomly assigned flavored e-cigarettes. Participants use the e cigarettes for vaping followed by ad libitum vaping. Participants also complete surveys and undergo biosample collection throughout the study.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Satisfaction and psychological reward	Satisfaction and psychological reward of e-cigarette (EC) vaping will be measured by the Modified Cigarette Evaluation Questionnaire (mCEQ). The mCEQ asks questions relating to satisfaction of using e-cigarettes on a scale from 0 (Not at all) - 6 (Extremely).	Minute 5 of vaping session, Minute 35 of vaping session
Primary	Sensory perceptions of EC vaping experience	Sensory perceptions of EC vaping will be measured by the Sensory E-cigarette Expectancies Scale (SEES) questionnaire. The SEES asks questions about sensory experiences associated with vaping on a scale from 0 (Never) - 4 (Almost Always).	Minute 5 of vaping session, Minute 35 of vaping session
Primary	E-cigarette puff topography	Will be measured with a topography device that records frequency, duration, and flow rate of EC puffs. These measures are combined to inform overall EC puff behavior.	35 Minute Vaping session
Primary	Levels of HPHC and other toxicant exposure from vaping e-liquids	Topography data collected for all participants for each of the conditions vaped will be averaged to produce four human-derived puffing regimens. Machine vaping will be conducted for each of the four e-liquids using the associated human-derived puffing regimens to determine the range of HPHCs and other toxicants in mainstream EC vapor.	After completion of sessions, estimated 4 years
Secondary	Economic demand breakpoint	The price point at which a participant is no longer willing to pay for a puff of the study e-liquid will be determined by an EC purchase task questionnaire.	Minute 35 of vaping session
