yes, it is possible to throw up from just weed. one time i smoked like a qtr, then the next day i waked and baked, went to my house and smoked 2 blunts wid my friends, then when they left i smoked another blunt of insane shit wid juss me and one other kid. After i was donte we went inside to make hot pockets, and while they were in the microwave i went to the br to take a dump but once i walked in the dump like changed itself into puke, and i started puking like crazy.

after i was done i washed out my mouth, walked back outside, and ate my hot pockets.
