@BeachBum13,
Usually children, friends and family have their own separate support meetings - unless they are also addicts. i.e. Al-Anon and Alateen
It's anecdotal, but every one I know who's gone to family support meetings has told me they benefitted from it.
You're best off to talk to your child's health professional about his particular requirements.
The majority of people who attend AA/NA are not criminals.
