According to the definition of the World Health Organization, drug addiction is a mental and sometimes physical condition that arises from the interaction of a living organism and addictive agents, and is characterized by behavioral change and other reactions that always include unavoidable coercion for occasional or regular drug addiction, either because of its desirable effects, either by avoiding the suffering that will occur if it is interrupted by taking, Addiction as a psychological and sometimes physical condition occurs as a result of the interaction between the living organism and the substance. The nurse is involved in the overall course of treatment and rehabilitation, and then the re-socialization of addicts. The nurse establishes collaborative goals with a rehabilitation team and carries out interventions that result in the best possible outcome for the patient. It is the main actuator of patient motivation to actively engage in the work of a therapeutic community and group therapy. Through the work in the therapeutic community, it is important for the patient trying to restore the desire for life, encouraging self-esteem and self-confidence and helping him to get involved in everyday life activities and develop personal realistic goals as soon as possible. Establishing good contact, trust and cooperation relationships are prerequisites for effective support and counseling of addicts and family members. Nurses educate their patients about the dangers of drug abuse, especially about changes within the body. They monitor their progress, help them adapt to non-drug life and provide them with the necessary education and support to help them adapt to life after leaving rehabilitation. Patrons' nurses and school nurses with specific interventions, such as education and counseling, contribute to better community information, especially youth and school children, the most vulnerable group for addiction development. In other words, the task of a nurse is to educate and educate the community on the problem of addiction every day in their work, no matter what level of health care.
