The 2024 European Web Survey on Drugs (EWSD) took place across 35 European countries, including Ireland, from May to July 2024. The objective of the 2024 EWSD was to determine patterns of drug use among a convenience sample of people aged 18 years and over in Ireland who have used drugs in the past year. As the EWSD sample is a non-probability convenience sample, it is important to note that this survey cannot provide population drug use prevalence data, and we cannot assume that the findings are representative of the drug using population in Ireland. In total, 2,406 eligible participants in Ireland took part in the EWSD, of whom 63.1% were male and 35.7% were female. The mean age of respondents was 32.1 years, and the median age was 30 years. Three-quarters (74.5%) were employed, 15.9% were students, and 3.5% were unemployed. The most common ethnicity was White Irish (83.9%), followed by any other White background (11.4%). Just 3.1% of respondents had received treatment for drug use in the last year.
