Thank you everyone especially since my post was so long. I have no problem turning my son in and have done so many times.
I don't know if he took this stuff or if someone else did so that is why I was not sure if I should call. I think I will talk to his probation officer about what he is up to out in the community.

After I read my post again, or should I say vent, I came to realize a few things. I do not like the life my son is living. I want him to change. I can't stand the fact that I cannot fix him.
It is out of my control, this is why it bugs me so much, as I am a fixer. I have to look at myself and deal with the co-dependency thing. My son is making choices, he knows right from wrong. I worry that he will die as he is so damaged by the drugs. He is 6'1 and probably only 130 pounds if that so that part is scary. But, I feel for the people that he is stealing from, I can't control that either. Maybe I have a control issue here.

I tell myself whether I am happy or sad, functioning or not, he is who he is and nothing I can do can change that. My being sad, or upset does not change the outcome for him, but it does cause me to suffer. I need to work on me, letting go and realizing only he can change himself. He doesn't want to bad enough or he would. I just need to let him be and focus on my other children which is what I am trying to do. Writing what I did helped me to see that. And your comments helped to and are greatly appreciated.
