affluent,highly educated parents="oh,Starshine is just going through (sorry...*thru*) a phase.Remember what we used to shoot up down at Washington Square Park? We used to hop on the "A" train (we jumped the fare turnstyles,of course),shoot up that sh*t and when we got back to our dorm at Columbia the RA didn't give a sh*t what condition we were in".

If the discussion were about marijuana, I’d probably agree with you, but heroin? You are way off base, IMHO. I cannot imagine any non-junkie parent, anywhere, thinking that intravenous heroin consumption is ‘just a phase’.
