Novel psychoactive substances ( NPS ) – knowledge and expe riences of drug users from Hungary , Poland , the UK and the USA

Background: The recent decade witnessed growing prevalence of novel psychoactive substances (NPS) among young people in Europe and elsewhere. The study, conducted in 2011 as part of the EU-funded ReDNet project, aimed at better understanding of motives behind the demand for NPS among youth as well as at their information needs in this regard. In addition to historical values, the lessons learned during the legal status of NPS may contribute to a more general understanding of use of new drugs and to current drug policies. Method: A self-administered anonymous questionnaire on NPS was completed via internet among young people from Hungary, Poland, the United Kingdom and the United States (N=1353) when NPS in general still enjoyed legal status. Results: The majority of respondents (82%) used NPS in the last 12 months and approximately half of them experienced adverse eff ects from these substances. The most frequent motives behind NSP use were willingness to experiment with new substances. However, sense of security and confi dence in their composition as legal products were also important drivers of their consumption. Desired psychoactive eff ects and risks associated with their use were rated as the two most vital pieces of information to improve their knowledge about NPS. Conclusions: There were some diff erences between participants representing diff erent countries, however, the study also revealed many similarities, suggesting emergence of global youth consumption cultures, including NPS use. Provision of information on NPS, including their positive and negative eff ects, should play an important role in drug policies. Since the time of the study some qualities of NPS (such as confi dence in their composition as well as quality and sense of security) may have deteriorated after delegalisation. On the other hand, opinions of NPS users suggest that delegalisation may have a deterrent eff ect for one third of their consumers while would not aff ect majority of them.
