Kids, don't try this at home

Nurse K: You don't remember being here for so long because you fried your brain with drugs. (Some times this nurse may be a little blunt...)
Susie Meth: Well meth will fry your brain. Cocaine will fry your brain. But heroine doesn't fry your brain.  Sometimes the world is a scary place and your don't want to deal with it anymore so you take a little heroine and you feel better.

Spoken like a true addict.
