How to handle teen drinking

[nothink]

DS is 15, his friends are 16. It's come to light that they've been drinking occasionally at sleepovers. We live in a semi rural location so they've been drinking in parks/recs until about midnight and then heading home. I didn't know this until DS overcooked it on vodka last night. When we got him home he vomited for 2 hours before falling asleep. He's really suffering this morning so hopefully he's leaned a lesson. I'm most worried about the safety aspect of being out in some dodgy places late at night and getting stranded somewhere completely hammered. He's got adhd and can be very impulsive. Would it be wrong to allow them to drink at sleepovers at our house - clearly not spirits but a couple of pre mixed drinks like Smirnoff ice? I have an 18 year old DD who drank from about 16/17 but only at parties. She was quite open about it and she's not gotten into the same state that DS was in last night.
We moved from overseas last year and it's taken DS ages to make two good friends, I'm worried taking a hard line will isolate him.

I don't think it is ok to supply alcohol to any other children without their parents' approval, so you need to think it through before you do this.

I would probably go down the route of no sleepovers and not encourage/facilitate drinking myself.

The problem is a lot of parents turn a blind eye to very risky behaviour, it's hard to trust them.

I think you would need to.speak to he other parents tbh,Times have e changed when i was that age ( im50) we regularly drank underage
I have a 17 year old and he rarely drunks ,plus he has Diabetes so I would worry about hoe this would affect his blood sugar, s .

Thanks, yes I think I need to start with speaking to the other parents. I'm feeling pretty shocked at the moment, and I've had about an hour of sleep. I had no idea he was drinking. I was just so happy that he'd finally found a group of friends

You don't have to know how to deal with it instantly, you can think it through.

That level of drinking isn't good for anyone, you don't have to be fine with it.

I think it's understandable you're a bit shocked.
