Later, the neanderthals were using it to start their fires and after inhaling for a while, that's where the phrase, "Gotta find a woman" originated.
And it definitely had a place in Noah's Ark's garden to help settle down some unruly animals.
So cannabis has been around a long long time. Adam's original name for it was "Wacky".
