A half gram really shouldn't have killed him, I've met people that have done a gram throughout a night.
But lets be honest, what a way to go out? Talk about a super candyflip, .5 of molly and 3 tabs of acid, you're practically already dead (ego wise). Have fun in heaven dawg, see you soon.
it probably depends on how much tolerance the user has. the people who have done half a gram per night.. how much were they doing it before?
erowid's measurements for dosages:

Have they confirmed it wasn't a bath salt RC?
