Found bag of weed in 15 yr olds cupboard. The game is on. WWYD??

So I knew he was up to something yesterday. Went to meet a friend (who I know is a bit dodgy) and after I picked him up he came in and went straight to his room. A mum just knows somethings amiss. So when he’s out at work today I have a little scout around, open a cupboard and get a whiff. Found it, taken it. He’s just come in, I’ve acted completely normal (and not like I’m wanting to throttle him) and now he’s up there and I can hear him scurrying around. Is he going to ask me or just panic himself?!
I did know he’d “tried it” about 2 months ago when I picked him up from the park and he was yellow, got him to admit it and he said he’d tried it and it made him feel ill so he’d never do it again. I agreed to not to tell his dad that time (we are not together) if he promised not to ever touch it again.
Dad will literally explode.
Dad has been doing some work in my house today whilst I’ve been out at work so DS is probably shitting himself thinking Dads found it.
How shall I continue to play this?!

Personally I'd be lighting a bit fat reefer but I'm not really the average MN user

Lord well I kinda can cos I’m a 40-something grown up and he’s a child! But I wouldn’t as I haven’t smoked that stuff in years and would probably throw up!

But it's still illegal, regardless of if you're 40 or not. It wouldn't exactly be setting a great example would it.

I'd steal it and smoke it while your kid is around so they know you know ha ha. Joking aside you need to have a word with them about drugs and how they can lead down to a harder drug path.

Thank you for your post. My own DS seems to be endlessly smoking as he vanishes for hours and comes in stoned, despite us not giving him any access to money. We are so worried and can’t get close to him, I feel we have lost him already I’m glad to hear your DS is working and has a better mindset, it gives me hope.
