This study is looking at ways to improve how remote breathalyzers are used by doctors and researchers to keep track of alcohol use. It aims to see if these devices reliably detect alcohol, especially since there's a period of up to 10 hours when breath samples aren't taken (like during sleep). Researchers will also check if a blood test for a substance called phosphatidylethanol (a marker of alcohol use) can help confirm if someone isn't drinking or if they're drinking late at night. You might be able to join if you are 21 or older and have had a DWI in the past two years (but aren't court-ordered to be monitored) or report frequent heavy drinking. The study is currently not recruiting, and plans to enroll 60 participants.
