ive got light headed a few times, mainly while smoking joints.

i once passed out for about a minute. me and some friends were having a huge session from a zong and i was trying to keep the pace with everyone else. i wasnt much of a smoker then so i was out of my league a bit (plus we had some really solid bud) and after the 3rd or 4th bowl i just felt really light headed and passed out.
next thing i know im on the bathroom floor with a cup of water asking what just happened..

i ended up feeling completely fine 10 minutes later and went out and got drunk.
