...Could smoking the thc cause this? He smoked it a few times that day. He said before he passed out he started getting hot and it was blurry. As he was falling a was trying to keep him up, his face was a little blue and he passed out for maybe 10 seconds. He was up before the ambulance got there.. he chose not to go to the hospital and said he felt fine. When we got home he called the family doctor and she told him to go to the ER we went and it was an 8 hour wait. He didnt want to wait so we left. He kept saying he was fine. I begged him to go to the hospital but he believes it was from smoking. He is feeling normal but im very very concerned. What may have caused this?
