My question involves criminal law for the state of: Pennslyvania

I am on parole for a 2nd DUI and part of my parole condition is no alcohol. My parole officer gave me a drug test today but I'm concerned if it will show positive for alcohol since I use mouthwash everyday.

I would imagine it might only test positive if they use a ETG test, but how common are they used? I just read about them online and now they have me worried.

I know I'm probably just psyching myself out- I haven't done any drugs at all or drank. But since I already spent time in jail I want to do everything in my power NOT to go back.

Am I just worrying too much or is there a chance that using household products which contain alcohol could show up positive on a drug test?
