Is approving esketamine as an antidepressant for treatment resistant depression associated with recreational use and risk perception of ketamine? Results from a longitudinal and cross-sectional survey…
Cannabis and Covid-19
The lockdown measures implemented to curb the spread of SARS-CoV-2 may affect (illicit) drug consumption patterns. This rapid response study investigated changes in cannabis use in a non-probability sample of cannabis users in the Netherlands during the early lockdown period. We fielded an online cross-sectional survey 4-6 weeks after implementation of lockdown measures in the Netherlands on March 15, 2020. We measured self-reported \motives for …
How do online and offline sampling compare in a multinational study of drug use and nightlife behaviour?”
Fluoramphetamine in the Netherlands
Limitations to the Dutch cannabis toleration policy
The role of leisure and delinquency in frequent cannabis use and dependence trajectories among young adults
Persistence and desistance in heavy cannabis use
Many cannabis users ‘mature out’ of their drug use, and factors of cannabis use cessation have been identified. However, very little in-depth knowledge is available about the mechanisms underlying this phenomenon. Criminological studies have gained interesting insights in desistance from crime, yet these perspectives are rarely used in drug research. This qualitative, three-year longitudinal study explored the processes involved in desistance fro…
The Role of Study and Work in Cannabis Use and Dependence Trajectories among Young Adult Frequent Cannabis Users
Life course theory considers events in study and work as potential turning points in deviance, including illicit drug use. This qualitative study explores the role of occupational life in cannabis use and dependence in young adults. Two and three years after the initial structured interview, 47 at baseline frequent cannabis users were interviewed in-depth about the dynamics underlying changes in their cannabis use and dependence. Overall, cannabi…
The Role of Parents, Peers and Partners in Cannabis Use and Dependence Trajectories among Young Adult Frequent Users
In a 3-year qualitative longitudinal study the role of social relationships in cannabis use and dependence in young adults (all frequent users at baseline) was explored. Overall, cannabis use and dependence declined. Changes in use were, for a considerable part, attributable to processes and life events in social relationships with peers and partners, while parents had little influence. Negatively experienced events often triggered increased use …
Cannabis Dependence and Peer Selection in Social Networks of Frequent Users
In a Dutch longitudinal study on the dynamics of cannabis dependence, at baseline 600 frequent cannabis users (? 3 days cannabis use per week in past 12 months) aged 18–30 years were interviewed. Nearly half of all participants (42%) met DSM-IV criteria for cannabis dependence in the 12 months prior to the interview. Participants were recruited by respondent-driven sampling; referrals were understood as proxy for social networks to explore peer a…
