Okay.. Going on three weeks ago I stayed with a friend at her college. Friday night we went to her friends' dorm. They were smoking marijuana, and we had some vodka. The time span is 8-12ish. I had around eight shots (my sister's estimate), very quickly. Then I wanted to try the marijuana, so I had a few hits for the first time.
Then the one guy told me to put *something* under my lip while I smoked. That's my question. I can't remember what it looked like or where he got it or exactly what he said about it. It was not a pouch, and it stuck to my lip, so I had to push it down. I thought it was marijuana.. I got pretty sick. I threw up a lot and I was confused when I was aware because I didn't understand how I should be so messed up-everyone else was fine. When I described it to my sister and her boyfriend later, they became convinced it was acid. Now my friend, though she did not see me put *it* under my lip, swears he's not a jerk and doesn't do acid and wouldn't have given me acid without telling me and she wouldn't have let me do it.. etc.
I'm aware I'm an idiot. I just would like to know if it's likely to have been acid or marijuana or whether there's something known for being used in conjunction with marijuana, placed under the iip? What's the most likely scenario?
Or should I just accept I'll never know, since the whole incident caused a fight with my friend, and I'm not about to ask the guy? Thanks.
