Long story but have been aware and v unhappy that my 15 yr old has been smoking weed for 2 years but recently found evidence as to use of other drugs over summer - ketamine , mdma, -at parties on nights when he lied about his whereabouts He owned up when confronted and says he is sorry to but obviously enjoys drugs and is attracted to party drug life style. I am terrified at his attitude and have to be honest don't see how to make him understand that we are not just out of touch parents. Anyone have any advice how to deal with this before it gets worse? School has been supportive. He's been seeing counsellor since I discovered the weed. He is highly secretive about his friends and whereabouts and while constantly challenging curfew he does adhere to curfew. Can't lock him up forever though. He says it doesn't cost much so money isn't an issue either. Doing well at school at moment.
