I suspect the stock isn’t falling because he smoked a joint. They are falling because there are all kinds of stories that he is acting like a lunatic and may be mentally unstable to the point where the board is questioning his sanity.
His bizarre behavior regarding the diver who helped rescue the stranded boys in the cave proves he’s unhinged. He attacks the guy, repeatedly calling him a pedo without any evidence to back his claim...then he apologizes, and then weeks later attacks the guy again saying he’s a pedo. Who in their right mind does that?

FWIW, I believe Musk is tired of being a CEO but has too much pride to call it quits on his own.
His stupid antics are a calculated move to be removed from certain responsibilities and retain his pride and ego and not be called a quitter.
