Well last summer I did actually OD on pot brownies. A couple factors came into play...#1 my buddy who made em put way more weed than the recipe called for...#2) I never got much off brownies/cookies in the past so I ate a whole bunch more than I should have. Well the hullicinations started about an hour later and lasted somewhere around 6-10 hours. And during that time I could not move my body not even an inch. My buddy called me to warn me not to eat em but I couldn't pick up the phone. My paranioa was through the roof, like a million times greater than smokin a sativa. I was hung over (from the brownies) the entire weekend, in a huge fog. I couldn't get high off weed for about 3 days after that. I couldn't even move my lips, let alone my body for the first 6-10 hours. I've never done acid, but I've tried salvia a couple times...this was far crazier than any salvia trip...it was not fun at all, I'll never eat any form of MJ again...and I have a pretty good tolerance to smokin for sure. That cop sounded fine compared to where I was at, no way I could have made a phone call and talked.
