My mum found my stash of Thai stick when I was about 16.
Sat me down & gave me the ‘drugs are not to be trifled with’ speech then made me roll a spliff & share it with her.
She then proceeded to take the piss out of it mercilessly, “sleeping bag”, etc… and showed me how to roll a decent 3 skin.
I don’t think the incident changed the way I viewed drugs and I did smoke on & off until my late 20s/early 30s but it definitely helped that I knew I didn’t have to be secretive about it. She wouldn’t let me smoke at home but I felt happy to talk to her about the fact I was going to the park for a cheeky spliff, that sort of thing so I guess in my case it helped for her to know what I was doing rather than wondering what was going on behind her back.
That being said, in those days it was grass or resin not skunk; some of the stuff about nowadays is more powerful to the nth degree that we had in the 90s. Maybe having a smoke with him will help you understand how strong it actually is. He’ll be more likely to open up with you about how much he smokes and you can approach the idea of moderation etc with him from a better position.
Oh, mini flapjack squares, toast with jam, gallons of tea & The Orb….
