People that "never come back".

dude was nuts already and he knew it. Met his type plenty before. Go rage crazy with partying and alcohol their first year or two in college and never really able to climb out of it. The fact the asshat took 10 hits his rookie time @ LSD should tell you enough man.

The fact the asshat decided to carve a peace sign on his forehead as well. LSD has big steps and each small step or hit upgrade is a huge responsibility. It's not for mental hillbillies.
