The Senehasa Drug Rehabilitation Center in Piliyandala uses the therapeutic community method to rehabilitate 60 youth with drug addictions. It is one of five centers run by the Mithuru Mithuro Movement, established in 1984 to help vulnerable people. The center uses techniques like affectionate motivation, practical guidance from peers, and exemplary senior members. Residents progress through orientation, primary treatment involving daily activities and self-evaluation, pre-reentry involving responsibilities, and reentry involving future planning. Funding comes primarily from resident families. The therapeutic community method has shown success, though social workers could further help with case management, counseling, and prevention.
