Haha, you guys are all bitching at each other so much. There is a clear cut right and wrong answer in this situation, however.
No, you can't just eat a nug of weed and get high. It can't happen.
In order to make THC psychoactive, it has to be decarboxylated; basically, it has to be heated to a certain temperature before it gets you high. BigBudBalls all ready brought that up.
That's why brownies, cookies, and the whole butter-making process are all effective methods of getting high; similarly, resin, because it has been burned, could get you high if you ate it. FDD has a thread on making edible hash by baking it in the oven, too.
Secondly, THC is soluble in oil, fat, etc; they don't break it down, but it stays in solution with them; again, this is how weed butter works. Unfortunately, THC is not water soluble, which is why weed tea does not work.
