title: [Emergence of novel psychoactive substances among clients of a needle exchange program in Budapest, Hungary].
abstract: In this paper the authors summarize experience of a drug service provider with the injecting use of novel psychoactive substances. Among clients of the needle exchange programme of Blue Point Drug Counselling and Outpatient Centre, the authors observed the spread of the novel substances since 2009. The extensive spread of the novel substances caused substantial change in injecting use patterns, thus in the usage of the needle exchange programme. The novel psychoactive substances appeared consecutively, so that this setting gave a unique opportunity to observe and track the emergence of these substances. The authors summarize the characteristics which are important for medical practice (risks, frequent use, severe psychopathological conditions) as well as special risks associated with these substances (substances with unknown composition and effect). They highlight the importance and role of the early warning system, monitoring the online sources of information and testing of samples containing novel psychoactive substances.
