It happened to me once but it was not even for a minute. Was standing outside a party smoking a big fat joint that people were passing around and then out of a sudden I felt super light headed, lights started to go off and next thing I know I'm being carried by the person that was standing next to me, then I had another person asking if I took anything else and was ready with a narloxone but I fortunately managed to tell them that I didn't take anything else and the friends I was with knew that as well so I wasn't poked with it. Bought a gatorade and was unfortunately not let back into the venue. I think it happened because I hadn't really eaten much that day and maybe it was too much weed for my tiny body even though I have a high tolerance, I think I'd also taken one drink so taking all those things into account it wasn't super surprising. If anything my general weed tolerance is surprising.
Actually another time I don't think I passed out but was in the verge of was a 4/20 event at the beach, I took a killer edible and had smoked a bit. So also not surprising.
If you really don't want to leave it then I'd start from tiny dosages and study how it makes you feel but also make sure that your blood pressure is not too low in general before smoking. Your health and safety come first. Also don't smoke alone anymore.
