Could have been laced. One of my first times smoking, I with a buddies, parents where gone, I got so trashed I knew I was going to puke I turned to my friend and asked him to get me a bowl or something so i could puke into it... I was so couch locked I wasnt going to get, so as i am about to hurl the fucker comes over with a cereal bowl. WTF that aint gunna do shit. Needless to say I puked everywhere.
If people ask jsut say it was food poisoning HAHA
