There was no heroin in the city—but all the heroin addicts were carrying on almost exactly as before. They were still scrambling desperately to raise the money—robbing or prostituting—to buy this empty cocktail. They weren’t in agonizing withdrawal. They weren’t getting gut-wrenchingly sick. They thought the “heroin” they were buying was weak, to be sure, and they were topping it up with heavier drinking or more Valium. But the core of their addiction didn’t seem to be affected. Nothing had changed.
