Musk, 'I use ketamine in the interest of investors' - News.com.au. Elon Musk says his use of ketamine, prescribed periodically by his doctor, "is in the best interests of investors" in Tesla and other companies he leads.
In an interview with former CNN anchor Don Lemon, Musk explains how what matters for Wall Street is "execution. So from an investor perspective, if I'm taking something I should continue to do so," he says.
