{Reference Type}: Journal Article {Title}: Harm reduction strategies for cannabis-related problems: a literature review and typology. {Author}: Pratschke J; {Journal}: Eur Arch Psychiatry Clin Neurosci {Volume}: 0 {Issue}: 0 {Year}: 2024 Jun 27 {Factor}: 5.76 {DOI}: 10.1007/s00406-024-01839-3 {Abstract}: Measures that seek to minimise the health and social consequences of substance use are an integral part of national drug strategies in many European countries. Against the backdrop of a high prevalence of cannabis use in the economically advanced countries, and increasing demand for treatment for cannabis-related problems, a range of harm reduction measures have been implemented by peers, statutory bodies and third-sector organisations. Based on a systematic review of the literature, the author describes these different forms of intervention, identifies innovative strategies and presents a simple typology that can be used when exploring existing measures or seeking to develop new policies. This typology covers different kinds of legal, socio-organisational and health-related interventions. All study designs were eligible for inclusion, with the exception of case reports, non-systematic reviews, editorials and news stories. Studies had to be published between 2011 and 2022, in English, and they had to refer to Europe, the Americas, Australia or New Zealand. A two-concept search was implemented using Embase.com and a number of other databases, combined with citation searches and manual website searching to improve coverage of research reports and advocacy documents. A total of 35 documents were deemed eligible, many of which rely on qualitative research methods.
