Coolmine is a drug and alcohol treatment centre providing community, day and residential services to men and women with problematic substance use and their families in Ireland. Established in 1973, CTC was founded upon the philosophies of the Therapeutic Community (TC) approach to addiction treatment. The TC is primarily a self-help approach in which residents are responsible for their own recovery with peers and staff acting as facilitators of change. Hence there is deep commitment to ‘community as method’ where the primary therapy and the main agent for change is the community itself. The most common features of TCs include that they are operated by residents, are based on a hierarchical structure according to seniority (length of time in the programme) and abstinence is the ultimate goal. Participants are expected to contribute to the general running of the community and to their own recovery by actively participating in educational activities, group and individual therapy.
