In Ireland and internationally, there has been much attention on the growing popularity of nitrous oxide. In response, the European Monitoring Centre for Drugs and Drug Addiction (EMCDDA) has published a report on nitrous oxide in Europe in order to increase awareness and to help stakeholders prepare for and respond to public health and social threats associated with nitrous oxide. As part of the EMCDDA report, the Health Research Board (HRB) compiled a case report on the current situation regarding nitrous oxide in Ireland.

Since 2006, the Growing Up in Ireland (GUI) study, a national longitudinal study of children and young people, has followed a cohort of children born in 1998. Four waves of interviews have been conducted with this cohort, when they were aged 9, 13, 17–18, and 20 years old.

The eight wave of the Healthy Ireland Survey, carried out by Ipsos and commissioned by the Department of Health, involves a representative sample from the general population aged 15 years and over to increase knowledge of the population’s health and health behaviours.

The Planet Youth programme is being implemented in an increasing number of regions in Ireland. There are currently six Planet Youth sites at various stages of implementation: Galway, Mayo, Roscommon, Fingal, Cavan, and Monaghan. Since the start of 2022, the three latter regions have published reports from their first waves of survey data. The reports present an overview of baseline data on health and wellbeing indicators as well as associated risk and protective factors.

The 2020 annual report from National Self-Harm Registry Ireland was published in 2022.

All individuals who were alive on admission to hospital following deliberate self-harm were included, along with the methods of deliberate self-harm that were used. Accidental overdoses of medication, street drugs, or alcohol were not included.
