napolitana869 Reviewed by napolitana869 on . WHY? Okay, so why in the hell do humans have cannaboid receptors in their brains? It's like we were put on earth along with the sweet jamaican red hair to smoke it. I just think that it's weird how they are there, for what other purpose than to smoke marijuana. Rating: 5
