And I don't mean passed out like sleeping, I mean fainted. I ask because last night I was smoking with a 40-something guy who took a hit from a bowl, held in the smoke while suppressing coughs and then passed out. My friend started saying his name but the guy didn't wake up until he shook him awake. The guy woke up not knowing what happened and we had to tell him. Everything was fine once it was over but it sure freaked us out. I think he must have just denied his brain oxygen by coughing while still holding his breath but I wanted everyone else's take on it. He was also drinking last night although he always drinks and smokes and he was drinking his regular amount when it happened.
