Elon Musk can be cagey about his purported drug use. After bombshell reports about internal concerns over the Tesla-SpaceX-Twitter-Neuralink executive using LSD, cocaine, ecstasy, and ketamine, Musk's line has typically been that it's not happening. More recently, he's shifted: OK, fine, it is happening, but it's just ketamine for depression, and actually it's good for shareholders. If his companies are doing well, Musk argued recently, and he's taking drugs while running those companies, then he should stick with the drugs, for capitalism's sake. One might pause at the logic, but Musk is hardly the only person making that calculation — plenty of people have come around to the idea that drugs are a decent work tool.
