Dr. Russell Newcombe, who had worked in the clinic, tells me the survivors “were immediately forced back onto the street . . . People who had jobs lost them. It split relationships up. People rapidly went back into debt and crime. The average person thrown off John Marks’s prescription regime would have been back in acquisitive crime within a month.” Whenever he’d see one of them in the street, he’d ask them what they were doing now. “Grafting,” they’d say—the local word for stealing to support your habit.
