Narcotics Anonymous is an international, community based association of recovering drug addicts with nearly 67,000 meetings in 139 countries worldwide. There are currently weekly meetings across Ireland.

The only requirement for membership is the desire to stop using.

October 7th 2019 marked the 40th anniversary since the first NA meeting was held in the old Rutland Centre in Clondalkin, Dublin. While other meetings had taken place sporadically before then, from the 7th October 1979 onwards there have continually been NA meetings in Ireland.
