what? lol.. i don't know.. but i think THC is already naturally in your brain or something and when you smoke cannabis it mimics that in your brain??... im not completely sure on what i just said lol.. but i think that's what i've read on before.. but what if this natural "THC" is completely gone in your body? or if cannabinoids receptors were destroyed in your brain and you smoked weed? would weed just create new "cannabinoid receptors" in your brain? or would you die or something? fly away? lol.. hmm this whole this is real confusing :P lol.. i was always wondering if you could absorb THC through your eyes too? lol
