For one you can't "OD" as you so claim. For two something that can happen when you take in to much thc or "OD" ing as you so call it and that would be called greening. But you won't die or go mental or what ever crap you think happens. You'll most likely murder a big bag of Doritos. It's not made by man remember doesn't have some effects on your body as a chemical does..... Moral of the story do research before you go full retard

In order to OD on weed you would have to smoke 1500lbs in 15 mins. I seriously doubt you almost ODed

But you didn't die
