It could also be what you have in your stomach. I remember making weed cookies with Arkantis. We only put about .7 grams each in three peanut butter cookies. Me, him, and another guy who only weighed 120 pounds ate them, and about an hour later we were totally fucked up. I felt bad for the other guy, because he just looked so fucked up and lost. This was at a state basketball game; I had no idea we were in the cities. Oh yeah, ate them on the fan bus.
