I'm no expert (not anymore...but "back in the day" I knew a little about Pot) but don't do this expecting to get stoned. I'm pretty sure cannabis needs to be heated to a certain degree for it to get you high. If you eat "raw" pot, you won't get a buzz. But, as soon as it's heated/cooked/smoked/vaped, the THC molecules are magically transformed into "happy times".
I'm not really sure where one would get "raw cannabis", except if you grew it. This looks kind of interesting, but I would suggest you do a little more reseach before you start growing a bunch of pot plants in the backyard. I'm sure the judge might look at you funny if you told him you only planned to "juice" it.
P.S. upvoted! Have a great one everybody!
