The NDTRS is a health information system that collects anonymous data about people in drug and alcohol treatment from general practitioners, low threshold services (that provide low-dose methadone or drop-in facilities only), outpatient and inpatient centres.

Through these interactive tables you can search for treatment data on eight different types of drug, including alcohol. The results of your analysis can be organised by year, age group, gender and geographical region of residence (county, HSE region, local health office, regional or local drugs task force area), and groups of variables.
