I have a usually lovely 13yr son.
For background. He really struggled in yr 7 and 8 as we had moved house and so he didn't know anyone at secondary school and he took a while to grow confident and make friends.
Since yr 9 he has a group of mates and we let him go out with one other person at a time on their bikes as exercise, which we were pleased about.
However in jan he came home one day and had obviously smoked weed and wasn't with it. We were really cross and he was grounded, had phone removed etc. We had the talk about it being dangerous to be out of it whilst he is out with his mates and tried to take a line of their needs to be a consequence but we want to keep an open relationship.
Since then I keep find puff bars / vaping in his room. I take them away and say it's not acceptable, he's only 13 etc and more importantly I don't want them in the house when he had younger siblings.
Last night I borrowed his phone to take a photo and saw on his photos that he has been vaping in his room. And even worse he smoked Weed when he was out again.
Again took his phone off him and said he's grounded. I was too cross last night to talk to him but this morning we had a chat and he admitted he spent £5 on weed.
School work wise he does the minimum and whilst he's very capable he doesn't make much effort and if more concerned about being 'cool' in front of others.
As he's my eldest I honestly have no idea how to tackle his behaviour. I love him lots but have explained to him that we have family with mental health problems they may of been caused by smoking weed as teenagers. He's also trying too hard to grow up when he's actually only 13.
Any advice or tips ?
