A "green out" may occur after a intake of cannabis, typically a green out begins with the person feeling like they are loosing a grip of reality following by possible vomiting amd eventual paralysis leading to a deep sleep. however if one goes through all stages but yet maintaines consciousness and does not fall asleep that does not count as a green out. People whom go through the process of a green out and do not fall asleep are true sick cunts as most people do not have the fighting will to overcome a green out once it is initiated.

New smoker: What happens when you green out?
Me: It's happened to me once, when I first started smoking green. I had too much too quickly and ended up being sick. I was straight in the shower when I got home.
New smoker: No good. I hope that doesn't happen to me.
Me: Just pace yourself at first and you'll be fine. I haven't worried about it in years.

Greening out is when one who takes cannabis (THC) products goes to sleep, throws up, or coughs and gags until the “high” goes away. Greening out is very common for new users of cannabis or users who smoke a stronger strain than what usually use to.
