We just found out our 13 year old has been smoking weed with his friends - for quite a long time.
We have a good relationship, very few arguments, and he's been honest with us about what has been happening. He's always home on time, he keeps in touch when he's out, he willingly shares his phone location, he keeps up with his homework and is rarely in trouble at school.
How worried should I be? I'm reluctant to ground/punish him, because I think this might just discourage him from sharing things with us in the future, or asking for help. We've talked about the dangers, and he has promised he won't try anything else.
All tips / experiences gratefully received!
