i read somewhere that our digestive systems can't really digest raw dense plant matter like weed without cooking it first, because the enzymes and stomach acid is not strong enough to fully break it down. it will get you high, as the thc breaks off of the plant matter and is absorbed by your stomach lining, but you would have to eat a lot, and your shit would be marbelized with green plant matter. the stems might hurt comin out your ass too.
