Broadly, the research detailed in this report was undertaken in order to provide the
first detailed assessment of the possible links between mephedrone use, violence
and other harms in South Wales. The research combines data from a survey of 67
users across South Wales with in-depth semi-structured interviews with 12
mephedrone users and 20 ‘expert’ practitioners who work with users in order to
further unravel the various impacts of mephedrone and, specifically, its links to
violence.
