Administrative database to regulate the dispensing of methadone treatment in Ireland. The CTL was established under Statutory Instrument No. 225 (Minister for Health and Children 1998) and is a complete register of all patients receiving methadone (as treatment for problem opiate use) in Ireland. When a person is considered suitable for methadone detoxification or maintenance, the prescribing doctor applies to the CTL for a place on the list and a unique number is allocated to the client.

The database is maintained by the Drug Treatment Centre Board (DTCB), on behalf of Health Service Executive.
