Weird Experience... anyone help?

For the past couple weeks, school's been out and I've been partying more, and smoking a little more than usual.... but last night something strange happened. I was at this party, laid back and just sippin on a beer and talking with friends, nothing crazy. This guys comes up and asks if I had a bowl, and I'm like yeah, I have one, but no bud. So he pulls out about an 1/8, and I hand him the bowl.
He packs one and a few other people get in the circle. We ended up smoking 2 bowls between 4 or 5 people, some pretty good headies, but not the dankest weed ever. I'm feelin better, and just a regular high, not super baked or stoned, but a comfortable high. So far I've had around 6 hits, and a beer because there was nothing else to drink. So I'm standing around the band, listening to the music, and I start staring at the door, and just feeling so relaxed. I zone out and suddenly wake up, on the ground with my head throbbing and my friends around me. I thought it was a dream at first, and was like wtf, and got up. What had happened? I had fell straight backwards and slammed my head on the ground, which knocked me unconcious for about 10 seconds.

Now I have no clue why the hell I just fell over... anyone know why this coulda happened? I wasn't drunk, wasn't even that high... and no other factors could have contributed...

You were standing right? Maybe you were standing still for too long with your legs straight. It can cause your knees to lock and blood won't be able to circulate through your body good enough and you will pass out. It happened to me at a kottonmouth kings concert once... I started feeling warm and I knew something was wrong, before I knew it everything was black and I felt this cooling sensation moving up my body(the cooling was my body falling to the ground) my friend picked me up a couple seconds later and I was surrounded by a big group of people just staring at me.

That could be what happened to you.

lol it sounds the same, but I had been standing the whole night, walking around... I was standing still when I passed out, but man that was crazy... Thank god I didn't live near that area where the party was... drunk people wouldn't stop harassing me lol, people kept asking if I was alright, or theyd give me a high five, haha twas embarassing but still funny.

Can you pass out from Marijuana like with alcohol? I didn't even smoke that much...

I would love to go to a Kottonmouth Kings concert, they rock~!

The only passing out you can do from marijuana is falling asleep.

It is pretty embarassing to pass out like that...I was lucky there was a concert everyone was more interested in, after a few minuets of people giving me weird looks and asking if I was ok they all kind of forgot about it. I fell right onto some girl and I guess it freaked her out a little...haha.

Marijuana affects your blood pressure, if you stand up suddenly, especially if you haven't eaten for awhile, I think it's possible to faint.
