I recently got on probation for drinking under age. I was a severe alcohol and I'm only 20. This is my first time being in trouble as an adult. However, because of my alcohol abuse I was put on UA and I am not certain what type ETG OR ETS, all I am aware of is that it tests for alcohol. If I drink now will I pass if I take a UA in November I believe its on the third when I see my P.O? Can someone please help me understand so I can know my limits.
