Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The proposed project will test three commercial cellphone breathalyzers against a police grade breathalyzer device.The study will test the accuracy of these smartphone breathalyzers at assessing Breath Alcohol Content (BrAC) against a standard police grade breathalyzer. This study aims to fill the knowledge gap by determining the validity of smartphone paired breathalyzer devices to accurately assess BrAC. Data collection includes collection of BrAC measurements, as well as survey data.

Commercial Smartphone-paired breathalyzers-Set 1

All subjects will first be given a priming dose of alcohol containing vodka designed to raise the blood alcohol content based on weight and gender. Blood alcohol content will first be measured with three commercial smartphone-paired breathalyzers: Drivesafe Evoc, Alcohoot, and BacTrack Pro which will be tested in a randomized order and recorded. Participants blood alcohol content will also be measured using the Intoxilyzer 240, a police grade breathalyzer device After the tertiary dose of alcohol, a nurse will perform a blood draw on the participants, which will be used to determine blood alcohol content.
