I agree, drug of choice doesnt mean you are an addict. Hell I would have been classified an addict 1,000 times over when I was in highschool. I am just lucky that I wasnt caught... well I was several times but they just conficated the stuff and sent you home in those days.
So when a program decides to accept court ordered kids they are really not a threat to the rest of the kids that are there. There is this misconception that court ordered kids are a danger of hurting the other kids. Seems it could be the other way around in mostcases.
