I was raised by an addict and don't want to scare you but have to say you won't know if your son is safe because you aren't there. My dad would pick me up from school events out of his mind. It wasn't safe. I don't know where you live or the laws involved but would definitely get a new lawyer who can provide you with better info and fight for you and your son. In the mean time, can you talk to the school or other parents who can support you and keep an eye out? The biggest thing I learned from al anon was yo not be ashamed of my dad's addiction. It wasn't my fault. And when I could be open about it and it was no longer a secret, I got the support I needed.
