My friend is 16 years old and has never gotten in trouble before. He is on probation for assault. He got into a fight at school. He just got put on Probation a month ago. He told me he smoked THC 2 days ago and is afraid he will fail his drug test because he is goin to his PO today. If he does it would be his first time offense for violation of Probation. If he does fail what could he expect to happen to him?
