Has been common knowledge for as long as I can remember. Of course, never listening to the insight of those before me, I tried a few times.

Some say they can get medicated by eating it raw. But I've been smoking pot for over 35 years, and eating it raw tastes nasty, and it never provided a buzz. I used to nibble on stems, and occationally still do use 'em for toothpicks on occation, but after a bunch of us ate about an 1/8 oz each of Columbian Gold a couple of decades ago and getting nothing from it, I never had the desire to repeat the expensive and nasty event. The party would have been a bore were it not for a friend with some Mexican dirt weed, which finally provided a few of us a buzz.

Eating cannabis raw
From the article:
"One of the drawbacks of eating marijuana leaf is the common complaint of stomach irritation. The top side of cannabis leaves are coated with thousands of microscopic thorns, and these sometimes cause minor intestinal irritation, even after grinding. For some patients, the use of leaf in Mari Pills is not tolerable, and in such cases, the use of buds alone, without the addition of leaf, is preferred. Note: the small leaves found in the marijuana flower tops are not as difficult to digest as the large "fan" leaves that grow from the stems. Also, the small bud leaves are far more potent than the larger leaves required for photosynthesis. As a general rule, the smaller leaves growing closest to the flower tops are closest to the plant's resin glands, and therefore have the greatest amount of medicinal compounds."
