lol but many plants are smelly without having an intoxicating effect... infact, a lot of flowers have smell in order to ATTRACT bugs and shit to fly around and pollenate them...

What could it BE!! did the plant grow on land before animals crawled out of the waters? because if that's true, it's like a prediction that some creature will come along one day with the right brain wiring so the THC key will fit in the Brain receptors!
