Summary

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.
