hey everyone.

last night i went to a concert, and i smoked marijuana. i am 16 years old and i am a male. i have smoked marijuana before on numerous occasions and nothing abnormal has ever happened. i was high before the concert, and i smoked again during the concert because i felt i was losing the high. but last night, when i was at the concert, i think i had a seizure. what happened was i was looking at the performer, and i looked at the big video screen for a second and i looked back. when i looked at the screen, it was very bright so i looked away back to the performer. when i looked away, my eyes did not adjust. all i saw was flashing streaks constantly. then my vision started to distort. all i could see was blurry stuff. and in a way, it was grey everywhere. if you have ever seen the movie Pitch Black starring Vin Diesel, what i saw was the monsters vision. everywhere. it was grey, and kind of streaks moving away from a center point away from me. also everything i saw, turned black and white. no colors. i saw black and white checkers everywhere. like instead of seeing a person, i would see him as if he was wearing a black and white checkered tights everywhere. and i saw everyone like that. I'm sorry its very hard to explain. and i almost vomited as well. i had a VERY strong feeling that i was going to. i felt like it was coming up but i was holding it down. also i remember i had a little trouble breathing. then i remember my head started to tilt left. and i started walking into people. my friend around me said that my eyes were rolling back and i was sometimes jerking. i couldn't control what i was doing. i don't remember some of this. but i remember when it was happening, my memory was looping. it was like my mind was constantly refreshing, back to a certain point. so every 3-4 seconds i would think it was that point again, even though 10 minutes had passed. i had extreme difficulty talking as well. i couldn't form a sentence because my mind was looping. because of the 3-4 second mind refresh, i couldn't form a sentence because every 3-4 seconds i would have to start over from the beginning. my friends saw what was happening and got me out of the extremely cramped crowd. when i got out i was going back to normal. remember, all of this happened during my high of marijuana. i don't recall any foaming or anything. when i got out i got some food and water and i was just back to a normal high of marijuana.

Please, did i have a seizure? Do i have epilepsy? or could it have been Marijuana that was laced with cocaine or something?
