In the community of drug users, individuals often use slang terms to designate substances as well as other terms related to their use that are often far away from technical terms. The aim of this work is to create an updated glossary of individuals addicted to drugs. In addition to slang drug terms it also covers terms related to various aspects of addiction issues. For a professional that deals with diagnostics and treatment of drug addiction, it is important to know the slang language for overcoming barriers, effective communication with drug users, identifying dependent individuals, as well as for the possibility of assessing the degree of identification of individuals with a subculture of drug users.
