Description From the time of its creation in the 1970s, the system of registration of drug users and those dependent on drugs served as a form of extensive control for the State over this part of the population. As a result of legislative and administrative changes between 2004 -2007, the law on the books and actual practice differ greatly. The concept of registration of drug users has lost its formal public health function and moved under the full control of the law enforcement agencies. In 2006, The Ministry of Internal Affairs (MOIA) initiated a reform of drug testing and registration, - which has lead to the consolidation of its control in this sphere.
