Hypothetically asking as I'm not actually in the situation. My dp used to take drugs. He has been clean off the hard stuff but I'm worried he will turn back to weed once lockdown eases up. If that is the case I've already expressed that I would not feel comfortable with him being around dc. I dont want that for them. Dp is convinced there is nothing wrong taking weed he thinks its harmless and it's his attitude that worries me into thinking he will turn back to it once he can start being around his weed taking friends. If this is the case, legally can I do anything? Would it mean him having less custody over dc? I'm really not sure where to start in terms on research on all of this but I want to be prepared just incase...
