A lawyer will talk to the D.A. and get a lesser charge, hopefully. I've never used one for marijuana, I just hoped the judge liked me. 10 weeks, turned into 11 because my final test had .14 ng of THC, of classes where a bunch of de-generates talked about drugs. It wasn't bad, except I traveled every week to come back to the class because I wanted to stay with a girl three and a half hours away.
