After smokin once with my friend and his 'rents i left their room and closed the door and as soon as i turned around I felt really light headed and fell down. I got back up real quick tho. Hasnt happened since.
if by "pass out" you mean just fall asleep in the middle of toking then yea i have a few times. sometimes it just gets to that point haha. but it's not like the passing out you think of as with alcohol where you puke, black out and forget everything. which is why marijuana is infinitiely better than alcohol. no reason to worry that you'll cross that line into unpleasantness.
I find that when i smoke and im by myself ill drift off into a sleep but im still thinking for about 10-15 min almost like im dreaming though im awake and ill wake up and remeber all i was thinking about and go get some food lol I know it sounds very confusing but for the real stoners, im sure you get what im saying..
nah its different than doxing off... u actually black out.. lose conciousness, fall or whatever. it cannot be good.
