Nick Ross investigates drug addiction. There was a time when drug abuse was big news: back in the 60s LSD, purple hearts and heroin advanced like a tide in Britain. Ten years ago this month the government responded: addicts were made to register, while the police, the courts and Customs clamped down on illegal trafficking. The tide was turned. Or so it seemed. This film inquiry now reveals a new and even more alarming threat, one that affects the old as well as the young. The Fix shows how people in Britain are falling prey to highly addictive medicines.
