Name changed for this as this may be controversial and I don't want this to follow me around, I just want other peoples opinions
DD is almost 18, she smokes weed occasionally and although I don't like it, if I told her she wasn't allowed she'd do it anyway and just try and hide it from me. DS (20) also smokes weed and I'm the same with him, when I first found out I did try and stop him etc but that didn't work and id rather know what they were up to instead of them lying. They do it maybe once a month if that.
DD has a friend who smokes with her when she does, his mum doesn't like it and tries to stop him. Apparently, they were planning on smoking today but his mum found out and messaged me and told me I shouldn't be allowing it and she doesn't want DS involved as he's easily led as he has ADHD so she told me I should stop DD from smoking or she doesn't want him talking to DD (something I don't think she can stop as they go to college together etc) and she said I'm irresponsible for letting my children smoke.
Aibu or is she?
