Hi dav.. im 36 now… but when i was 14 i was exactly the same.. and my mum was exactly the same as you. I was really bad on weed at the time. It effected my GCSEs, and its one of my biggest regrets and it still bothers me now. I just messed around in school all the time. My mum was screaming at me all the time, and im ashamed to admit it i put holes in a few doors in our house through anger.
My mum and dad was totally against drugs and both had good jobs. I quit it in the end.
But i had a great time with my mates and great memorys, but i wish i never hung around with any one that did drugs. Thats a major factor.. one bad apple does really spread.
How is he doing in school?
The only things i could suggest is… keep making him aware of the bad side effects.. show him this message were i regret messing my GCSEs up and my career.
He is not really going to stop till hes had enough. I hated the stuff in the end and it made my chest really sore.
I quit it on my own and it was hard, and i wont lie to you it does lead to other drugs.
He could just grow out of it.
