The term “addiction” is directly related to the concept of “drug” (from Greek – numbing, stupor). For the first time, the term “drug” was applied to morphine-like alkaloids, opium derivatives, and their synthetic analogs. Currently, the term “drug” is a psychoactive substance that is listed as prohibited for public use.
According to the description of the World Health Organization “addiction” is a condition related to mental disorders, against the background of a strong desire to take psychoactive substances (including medications) from among those prohibited for free use, leading to systematic use, with harmful effects on the body and pronounced long-term consequences. The abuse of drugs other than those listed as “prohibited” is called inhalant abuse.
