My son started smoking pot when he was 14 years old. Actually got caught in the Middle School. I remember I couldnt believe how he shrugged it off like it was nothing. (God how I wish I would have realized there was a problem right from then) I remember specifically when his health teacher in high school said to me...hes using drugs. I couldnt believe she said that. I thought he was just a kid who made stupid mistakes. Little did I know...there would be lots of hell to follow. Oh how I wish I would have gotten that kid help back then. But everyone kept saying..."he's a kid...it will pass..dont worry. Big mistake!!!!! Get him help immediately or I promise it will escalate. Eventually he will get caught and there will be so many bigger problems. He definitely must be selling with all that cash. He could possibly be selling for someone else also. I would push to get him some counseling or something.
