The National Drug Advisory and Treatment Centre, now known as The Drug Treatment Centre Board (DTCB), was established in 1969 and is the longest established treatment service in the country. It was originally located at the 'Charitable Infirmary', Jervis Street Hospital, Dublin 1, which was established in 1718, the first voluntary hospital in Ireland.

The current Chairman of The Drug Treatment Centre Board is Mr Dan McGing (Appointed July 2010). The Drug Treatment Centre Board was set up by statutory instrument in 1988. Previously funded by the Department of Health and the Eastern Health Board, it now receives its funds through the Health Service executive.

It provides effective, high quality and client focused treatment for the population it serves. This is provided in a caring, professional manner in an atmosphere cognisant of the varied individual needs of the client population. It offers guidance and training to other professionals working in the area of substance misuse and contributes to policy development in drug and addiction management. The DTCB is represented on the National Drugs Strategy Committee and the National Advisory Committee on Drugs.
