I’m not sure what makes someone think, “hey, why don’t I snort bath salt?”
Yeah, I've wondered about that kind of thing too. You can go all the way back to when someone said, "you know, that leaf on that plant.... I wonder what it'd be like to light it on fire, and inhale the burning emissions." There's certainly more examples from further back. Then again, I like lobster and who was the first guy who thought, "let's boil that sucker and eat the innards"?
