Kattaran New Member. I've heard that the best way to get high from ingesting THC oraly is by cooking out the THC in oil and butter. That doesn't mean that you wont get high if u eat raw weed because you will. It will take longer for you to feel and, depending on how much you eat, how high you get.ou don't need heat. If you could get it down, you could eat raw weed and get as high as a kite. The advantage of mixing weed that's going to be eaten with fats or oils is that the cannabinoids will get absorbed more quickly as the food passes through your gut. You absorb all of the cannabinoids from raw weed, too.
