honestly, i just think it affects people in different ways, cause i have friends who get stoned like i've never been. one of my friends will just periodically tweak the fuck out when he's high, theres no other really way to describe it, he gets all twitchy and fucked up and like flips out in really hilarious ways, but it just blows my mind b/c marijuana could never do that to me, no matter what or how much i smoked, which i think is a good thing for the most part, cause i like just chillin out, but sometimes it seems like it'd be fun to just lose it like some people i know do, but i guess thats why theres acid =)
