well most of it depends... if i'm smokin a blunt then i need at least a gram. but if i'm smoking out of my bubbler that is currently behind some tree then i could use about 1/2 a g and i'm set for the nightdamn! I can stretch a gram pretty far! If I rip more than one gram at a go I'm smashed! I'll smoke 1/5-1/4 gram at a time, but I like to stay "buzzed" all day, not really "stoned"
