I dont know where you live or what treatment centre your going to,,but,, My 16 year old daughter is in treatment for adhd
in kitchener and before she went
in to treatment,,we looked on the internet at the place she was going and we found out everything we needed to know,,like phone privilages,,visit's,,her laptop,,rules ect.. She is only 16 and went to treatment for behavioral problems not drug use, but I am sure you can look it up just the same have you tried yet??
