Hmm. We have just discovered evidence in DS2's pockets of dope smoking - and I have picked up a couple of references to it on FB, so I'm contemplating what to do next.
DS2 is 16, and I knkow his social group are doing a lot of drinking too - and both of these concern me.
I think I will be doing a stiff talking to, focusing on the illegality of it first. I suspect we may need to monitor just how often he is going out with this crowd. As it's the summer holidays he's out more than he would normally be during term time.
I don't know who is buying either the dope or the alcohol - it certainly won't be DS2 as he looks way too young.
It's difficult to know how to really handle this properly. I'm resigned to the fact that they will want to try these things, but I hate the idea of drug usage, regardless of whether it's illegal, especially at this relatively young age.
OP - I'm not sure what to advise you, other than given her age, you can still stop her going out so much/as often? I may also follow your idea of removing money for a while, so that he can't go out either.
