During the 1980s illegal drug use in Britain appeared to be increasing at an alarming rate and spreading across the country on an unprecedented scale. An apparent growth in the use of heroin caused particular concern: the number of known heroin addicts rose from just over two thousand in 1977 to more than ten thousand by 1987. Moreover, heroin use was being reported in urban areas throughout the country. This was in contrast to previous decades, when it was thought that drug use was largely confined to London. By 1985 the Conservative government was able to assert that “the misuse of drugs is one of the most worrying problems facing our society today.” Growing fears about drug use prompted a flurry of activity from both central and local government, from law enforcement bodies, voluntary organizations, and health professionals.
