Why do people use new psychoactive substances? Development of a new measurement tool in six European countries.

Introduction: New psychoactive substances (NPS) pose a public health threat. Many studies have tried to identify the reasons of NPS use; however, none of them have so far used any standardised measures. The aim of this study was (i) to develop and cross-culturally validate the New Psychoactive Substance Use Motives Measure (NPSMM) and (ii) to compare motives of NPS use across countries and user types.

The transparency paradox. Building trust, resolving disputes and optimising logistics on conventional and online drugs markets.

Methods: Qualitative and quantitative data from a recent German project on conventional (offline) small-scale drug dealing as well as qualitative case studies on four online vendors operating on Agora market are used to explore alternative practices for building trust and reputation.
