Rebelson.
I am so sorry to hear this. You know where I'm at right now with all of this.....
You don't know for sure and you are being way TOO INVOLVED right now for your own good. I know that the guys know how to beat the breathalyzer. My son told me about it but at that time he wasn't doing it.
I have to go to a meeting but PM me or email me if you want to talk more.
Remember you can't control any of it.
Hugs and stay strong.
