I would imagine it takes more weed to get stoned if you're eating it than it does when you smoke it. Say if I made a chocolate cake or something, how much weed would I have to put in it to get really stoned? The weed I have is pretty potent, half a joint gets me nicely stoned. How long does it take to work when you eat it? How long does it last? Does the high feel different from smoking it?
