okay so today i found some tylenol number threes, with codeine i had 7, me and my homeboy split em, 3 and a half each about an hour later we met back up with our other homeboy we smoked some bowls, etc. an hour or so later were chilling smoking and my friend who took the pills started to sit down cuz he didnt feel good. he started sweating and his face got super pale i can tell cuz he mexican lol he wasnt talking for liek 5 mins then he just said "dude, i just felt like i was dying, i couldnt talk or anything, and if i stood up i woulda passd out" he just said he felt waves of dizzyness and lightheadedness and just feeling like he was about to die lol . then the rest of the day he was fine. so my question is, was it the pills, and if so, what caused it?
