Your worst experience?

One of the first time i smoked it was during my highschool's carnival i hitted 2 times on a royal blunt (hash+weed) and then there was a big show in the center of my highschool.
I went into the crowd and when i was in the middle of them suddenly i started to lost the view. A friend near to me grabbed me and pulled me out the crowd. I sat on a chair for 2 min and vision came back. It was scary but i never experienced a sht like that since then.
