So, i started smoking last year but not a lot, once everyweekend, and yesterday me and my friend smoked some, and at first it was the best high i had ever had, everything was hilarious and we went to the shop to get snacks and then mcdonalds. So i we were standing in the queue and all of a sudden i began to feel sick, then everything went black and i lost my balance and just fell over but i don't remember anything, only getting up and leaving, it pretty much ruined my night and i don't know if i'll smoke again after that. Can someone explain what happened or why this happened, my friend had the same stuff and it was his first time.
