The anarchist grew animated as he explained his plan to subvert a pillar of global capitalism by teaching the poor to make their own medicines — pharmaceutical industry patents be damned.

Hank Greely, who directs the Center for Law and Biosciences at Stanford University, said he doesn’t object to “self-experimentation” by patients who want to try Laufer’s recipes.

“I’m relatively willing to let competent adults do stupid and reckless things if they don’t hurt anyone else,” Greely said. But if someone follows Laufer’s directions and dies “from a mistake he makes, or a mistake one could predict his users might make,” it creates a “moral liability,” even without a legal one, Greely said.
