I agree with Daz on this one be very careful. I work closely with Children’s services. I’m in no way saying don’t access the service, but I am saying be very careful. He will Automatically be referred to a drugs service which will probably be the best thing, however that can go two ways. One positive where he engages well and attends the recovery programme or two it could apply pressure which could lead to relaspe/lapse. As part of treatment SS will probably want drug testing, but that’s even if it gets pass early help stage. Even then it could be something they request. Sadly that depends on location and social worker.
So long as you’re the protective factor you should be ok.
They also look at safety in terms of dealers etc.
I hope things go positively for you and you all get the wrap around support you need.
Take good care.
