Follow-up of a representative sample of heroin addicts.

The 3.5 year follow-up status of a representative sample of addicts prescribed heroin at London Treatment Centres was ascertained using Home Office records. Fifty-six percent were still receiving opiates from Clinics with 39% still receiving heroin. Six percent were dead, 2% were in prison, while 34% were not know to be using drugs or to be institutionalized. Outcome was significantly related to age with the older sample members being more likely to be prescribed opiates and less likely to be classified as "Off" drugs. This result is in contrast to American reports and is possibly indicative of a perpetuation of dependency encouraged by current treatment methods. Outcome was further partially related to a typology of life styles formulated from date from the original samplw with those who were the most Stable in 1969 being more likely to receive heroin on prescription in 1973, and those classed as Loners and Two-Worlders in the original survey being the most likely to be classed al "Off" drugs by the Home Office.
