Heated or dehydrated? There are many who will claim that in order for pot ot reached it's potential it must be heated. I believe the usual explanation is this converts thca into thc. But I am not a chemist.
In my personal experience eating really dry, like totally dehydrated weed, it will get you very high. The main difference from diffusing it into an oil/fat is that the buzz is slower in coming on because you also have to digest the plant material.
