'Surfing the Silk Road': a study of users' experiences.

The International journal on drug policy November 1, 2013 Marie Claire Van Hout, Tim Bingham 211 citations

The online drug marketplace Silk Road, operating anonymously on the Deep Web since 2011, attracts users primarily for reasons of curiosity, concerns about street drug quality and personal safety, product variety, anonymous transactions, and convenient delivery. Based on systematic online observations, monitoring of discussion threads over four months, and anonymous online interviews with 20 adult users, most participants were male, in professional employment or tertiary education, with drug use histories ranging from 18 months to 25 years. Favorite drugs included MDMA, 2C-B, mephedrone, nitrous oxide, ketamine, cannabis, and cocaine. Vendor selection relied on trust, transaction speed, stealth, and product quality. A minority reported customs seizures, and many described a displacement away from traditional street and closed drug markets toward Silk Road.

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

Journal of psychopharmacology (Oxford, England) June 1, 2020 Annemieke Benschop, Róbert Urbán, Máté Kapitány-fövény et al. 35 citations

A new questionnaire, the New Psychoactive Substance Use Motives Measure (NPSMM), was developed and validated across six EU countries with 3,023 users from three subgroups: socially marginalized individuals, nightlife attendees, and online community members. Factor analysis revealed five consistent motives for using new psychoactive substances: coping, enhancement, social, conformity, and expansion. Motives varied by user group: marginalized users scored higher on coping and conformity, nightlife groups on social motives, and online community users on expansion motives. Different types of NPS were linked to different motives—expansion with psychedelics and enhancement with stimulants—while coping, social, and conformity motives were more tied to user groups. The NPSMM is a valid tool for measuring these motives.
