Hi, I have smoke weed twice in my life, the first time nothing happened to me except for I felt heavy. The second time, I could not hear, there was loud buzzing, I couldn't see well (blurry), and I felt tingly all over. After a while I 'passed out' but the people I was with said it looked like I had a seizure. I was wondering if anyone had any clue as to why this happened. I have been assured the weed was not laced. Also, I am allergic to penicillin, I don't know if there is any correlation.
