oh,diane, i am so sorry. i know how hard it is to see our children come out of jail & start the same thing over.what a let down. he says he does not want to quit, so u are powerless which you said.how old is your son?i am sure u said but i have forgotten. i feel really bad for your parents.they do not know any better.i remember when i didn't. all you can do is tell them. i would also tell them that he spent there money on coke.i would not hide anything. i am saying a prayer for your son & you & your parents. i am sending you a big hug.
