  • Global patterns in small-scale cannabis growers’ distribution practices

    Open Access•Thomas Friis Søgaard, Julie Elisabeth Brummer et al.•ARTICLE•International Journal of Drug…•2025

    We discuss the implications of the findings on the structural process of import-substitution in low-end cannabis markets, including a growing normalization of cannabis supply

  • Impact of the Covid-19 pandemic on cannabis cultivation and use in 18 countries

    Open Access•Bernd Werse, Gerrit Kamphausen et al.•ARTICLE•International Journal of Drug…•2025

    This study is the first to document an increase in cannabis cultivation activity following COVID restrictions. Increased home cultivation was not only driven by higher use as a result of home isolation, but also by disruptions of wider illegal cannabis supply. Limitations of this study include the non-representativeness of the sample as well as differences in approaches and duration of restrictions in different countries

  • How and Where to Find NPS Users

    Open Access•Dirk J Korf, Dirk Korf et al.•ARTICLE•International Journal of Mental…•2019

    Use of new psychoactive substances (NPS) across Europe remains a public health challenge. The study describes potentials and limitations of methods in a transnational survey of recent marginalised, nightlife and online community NPS users in Germany, Hungary, Ireland, the Netherlands, Poland and Portugal ( n = 3023). In terms of demographic profile, drug use history and type of NPS, different methods reached different segments of the NPS-using po…

    Open Access•Katalin Felvinczi, Annemieke Benschop et al.•ARTICLE•International Journal of Mental…•2019

    New psychoactive substances (NPS) continue to be considered as a major public health concern in many European countries. The study was implemented within the framework of a transnational project of six European countries (Germany, Hungary, Ireland, Netherlands, Poland, Portugal). Our aim here is to report on the distinct and differentiating characteristics of marginalised NPS users. Three subgroups of a total of 3023 adult NPS users (socially mar…

  • The challenges and benefits of analyzing feedback comments in surveys

    Open Access•Tom Decorte, A Malm et al.•ARTICLE•Methodological Innovations•2019•Citada por: 6•Referências: 34

    It is common practice in survey questionnaires to include a general open and non-directive feedback question at the end, but the analysis of this type of data is rarely discussed in the methodological literature. While these open-ended comments can be useful, most researchers fail to report on this issue. The aim of this article is to illustrate and reflect upon the benefits and challenges of analyzing responses to open-ended feedback questions. …

  • Sharing, Group-Buying, Social Supply, Offline and Online Dealers

    Open Access•Ross Coomber, Leah Moyle et al.•ARTICLE•International Journal of Drug…•2018

    Open Access•Marie Claire Van Hout, Annemieke Benschop et al.•ARTICLE•International Journal of Mental…•2017

    Continued diversification and use of new psychoactive substances (NPS) across Europe remains a public health challenge. The study describes health and social consequences of recent NPS use as reported in a survey of marginalised, nightlife and online NPS users in the Netherlands, Hungary, Portugal, Ireland, Germany and Poland ( n = 3023). Some respondents were unable to categorise NPS they had used. Use of ' herbal blends ' and ' synthetic cannab…

  • Growing medicine

    Open Access•Pekka Hakkarainen, Vibeke Asmussen Frank et al.•ARTICLE•International Journal of Drug…•2015

    There is a wider demand for licit access for medical cannabis than currently available in these countries. Ideologically, medical growers can be seen distancing themselves from both the legal and illicit drug markets. From a harm reduction perspective, it is worrying that, in the context of present health and control policies in these countries, many medical growers are using cannabis to treat serious medical conditions without proper medical adv…
