Mischa's Little Sister Checks Into Rehab

How would a 19 year old even get prescription pain killers ? I don't get young hollywood either. I am 21 and I have never and will never act like that. Parents need to start stepping in.
 
Mischa (?) is smoking weed in that one pic.

As for her sister being addicted to pain killers, I think her addiction is probably more to an illegal substance. I saw pics of her on either Cobra snake or Last night's party with what looked like a couple of ecstacy tabs crushed up in her mouth.

I guess it is more publicly acceptable to claim addiction to prescription pills than illegal street drugs.
