The covert nature of drug misuse means that it is difficult to know the number of people misusing drugs. Various estimates of the number of opiate misusers have been made and these range from 6,500 to 13,500. It is known also that the vast majority of opiate/heroin users reside in the greater Dublin area.
The number of people receiving methadone treatment for opiate addiction at the end of February was 5,958. Some 3,264 of these were attending treatment clinics in the Eastern Regional Health Authority area, 488 were attending the treatment clinic at Trinity Court, Pearse Street, 205 people were receiving methadone in prison, 71 were receiving treatment in clinics outside the ERHA, 1,832 were being treated by general practitioners in the ERHA and 98 were being treated by general practitioners outside the ERHA.
Details of the number of people on methadone treatment in the years listed by the Deputy are as follows:
