Study Details
Study Description
Brief Summary
The purpose of this research study is to find out about ethanol-containing e-cigarettes impact ethanol breath tests, field sobriety tests, or other tests of sobriety. Ethanol is a common part of e-cigarette liquids.

Outcome Measures
Primary Outcome Measures
- Preliminary breath test for ethanol [Conducted before and after the e-cigarette is used by the participant, at multiple time points (change from baseline reading at 27, 35, 40, 45, and 56 minutes after e-cigarette use)]
Initial type of breath test used (gives percent blood alcohol concentration)
- Evidentiary breath test for ethanol [Conducted before and after the e-cigarette is used by the participant, at multiple time points (change from baseline at 29, 37, 42, 47, and 58 minutes after e-cigarette use)]
Secondary type of breath test used (gives percent blood alcohol concentration)
- Standard Field Sobriety Test [Conducted before and after the e-cigarette is used by the participant, at multiple time points (change from baseline at 30 and 49 minutes after e-cigarette use)]
Test used to determine sobriety
Other Outcome Measures
- Direct Effects of Vaping Questionnaire [Administered after e-cigarette use (at 39 minutes after e-cigarette use)]
Questionnaire that asks participants about their vaping experience (10 questions, each scored from 0 - 100)
- Biphasic Alcohol Effects Scale [Conducted before and after the e-cigarette is used by the participant (change from baseline at 39 and 54 minutes after e-cigarette use)]
Questionnaire that asks participants about effects associated with alcohol use (14 questions, each scored from 0 - 10)
- General Labeled Magnitude Scale [Administered after e-cigarette use (at 39 minutes after e-cigarette use)]
Questionnaire that asks participants about flavor sensation, harshness/irritancy, and "throat hit" of the e-cigarette (3 questions, each scored from 0 - 100)
