 How many people use drugs and alcohol in Ireland?

Drug prevalence is the proportion of a population who have used drugs in a given time period.

Every four years the National Advisory Committee on Drugs and Alcohol, and the Northern Ireland Public Health Information and Research Branch, commission a survey of the general population to estimate the number of people in Ireland who use drugs and alcohol. The 2014/15 survey involved 9,505 people (7,005 in Ireland and 2,500 in Northern Ireland).

The main purpose of the European School Survey Project on Alcohol and Other Drugs (ESPAD) is to collect comparable data on substance use among European students aged 15 and 16 in order to monitor trends within, as well as between, countries. The 2015 wave of the ESPAD survey marked the sixth occasion that Ireland has participated in this collaborative international project.
