I have before, I don't plan to again. I don't care if you do, except not inside, smoke smells and ruins electronics. My first time was my accident, my roommate made pot brownies. You'd think she would have the decency to tell me, but no. I took two... big pieces, and ate them. Little while later I got what I'd imagine was the munchies, and the first thing I saw was the brownies, so I ate the rest of the pan.
