Improving Remote Breathalyzer Procedures used by Clinicians and Researchers to Remotel
Monitor Alcohol Use
This project is a 4 week procedure where participants are asked to blow into a
breathalyzer 4 times a day while also wearing an ankle alcohol monitoring device.
Remote breath alcohol monitors have been increasingly adopted for use in clinical,
research and forensic settings to monitor alcohol use, offering several key advantages
over other available monitoring methods. However, it remains unknown if remote breathalyzers
reliably detect alcohol use because there is up to a 10-hour window of time when breath
samples are not obtained (to allow for sleeping). Additionally, we will examine whether
a supplemental measurement of a blood alcohol use biomarker (phosphatidylethanol)
can confirm abstinence and/or detect individuals' alcohol use.
