Elon Musk is accused of promoting drug use among his business associates and board members at Tesla and SpaceX.

The Wall Street Journal cites at least three directors involved in drug use with Musk, with some feeling pressured to partake.

The close relationships and financial dealings between Musk and his board members may conflict with SEC rules.

Concerns include erratic behavior, possible legal infractions, and vulnerability to blackmail, potentially affecting U.S. government contracts and security clearances.

These allegations call into question the independence of Tesla's board and its ability to govern without influence from Musk's personal conduct.

Musk has not issued a response to these allegations.
