Have you ever passed out/ blacked out from smoking weed?

This shits happened to me too. One day I smoked outside with my sister and it was only like a bowl or two which is not as much as i normally smoke at all and it was some good east side weed. Btw I live in Vegas so it's really hot here . Then right after I smoked I went to the mall and I was feeling fine up until I started to come down from my high. At first my heart just started beating really fast and then I started to feel lightheaded. My eyes were still open but all of a sudden I couldn't see and I felt my legs start to give out and I just fell into a rack and knocked it down (lmao). I couldn't get up until my sister Picked me up and then I felt fine but still kind of light headed and weird. Then I went to the food court and when I started walking it happened again then after I ate and drank I felt better. I still smoked the next day too and it happened again. I smoked after that and it didn't happen for a while but it happened again recently? The last time was the worst and the scariest. My friends all said I looked dead and pale and I passed out with my eyes open. It was really weird but i haven't stopped smoking
