Drug use is one of the main public health problems in the Americas. The need for drug treatment, rehabilitation and care services is increasing, and solutions are therefore needed from both governments and civil society. In the Americas as a whole, such services are often provided by non-governmental organizations. CICAD’s Demand Reduction Unit cooperates with civil society organizations that address problems related to drug use, to seek adoption of scientific evidence-based practices in the treatment of drug use in accordance with international quality standards.
