When DS was about 15, his school had a parents meeting, all together in the school hall. The speaker, talked about not panicking if you find some weed, a lot of kids try it, just a phase, nothing to worry about. Our DS didn't worry us. He was very, almost too, righteous, he has also seen his grand dad going through health he'll due to smoking, so he couldn't have been more anti smoking. We never thought he would be stupid enough to smoke, never mind try weed, or anything else. How wrong we all were. We found out years later he tried weed when he was about 15, we had no idea. He then went to Uni, got more involved with that scene. There then followed 20 years of him not being able to hold down a job or relationship, arguments, him disappearing for months at a time. It finally culminated when he was 40 he went berserk, attacked DH in a rage which resulted in the police being called, the police doing nothing but move him on. He found a flat to live in but wouldn't discuss anything with us. A year later, he was £2,000 in arrears. His landlord, who was a friend had to break in as he had barricaded himself in. He was sectioned, 3 months in a secure unit suffering from drug induced paranoia. He is out now, tge drugs turned him into a zombie. Lethargic. No motivation, no conversation. He will probably be on medication for the rest of his life. His life, our, his siblings is ruined. The frightening thing is the number of people in the same position. Kids with a lot of potential whose lives, and their families lives, wrecked, from what started with 'a bit if weed' These are not kids from broken homes, disadvantaged backgrounds or other stereotypical problem families. These could be your DCs or grandchildren who would never touch drugs. Be alert at all times. His friends were all good, many have gone on to be high earners, but if your LO is one of the many who go the way of our DS you have a living nightmare ahead of you. If you get any hint of weed use, stamp it out if you can. A row with a 14 year old is preferable to seeing a promising, intelligent teenager turn into a shambling wreck of a man.
