Meth hands down is the worst.
Living in a small desert town I see the worst side of it everyday...
Id MUCH rather deal with a heroin junkie or pill popper whos probably nodding out or at least stayin chill. Who knows what a tweeker is gonna do.
People still smoke crack? jk but thats more ghetto and big city. Again id still rather deal with a shitty crack head than a gacked out tweeker.
