My stepson (over 21) got convicted of DUI in Georgia: first offense. He is visiting his probation officer for his first visit of a year's probation. He admitted to me that he smoke marijuana for the first time in a long time just 10 days ago. I don't think he is chronic user despite how irresponsible he may be right now. He said he just didn't think straight. Either way, should he expect to be drug tested?
