Is this normal while smoking weed
SO YESTERDAY I had the scariest experience in my life, me and my friends were smoking 2 blunts one of mid and one of dro, after like 15 mins of smoking my vision was getting blurry I thought I was just tripping but no the blurriness was getting worser and worser and than I couldn't see, my whole body felt like it was getting shock, and I couldn't breathe, I tried to feel my heart but I didn't feel it.
my friends said my face was getting green, they gave me a Arizona drink and water and then I threw up and I could see and breathe... I went in my friends house and just sat and rest and I was fine after 3 hours
