[Complications of contaminated drugs: how to reduce the number of future victims?].

Serious complications of drug abuse are frequently seen in acute care. When the clinical signs and symptoms of drug use are discordant with the expected clinical features of the intended substance used, it may involve misleading, contaminated and therefore dangerous illicit drugs.

Changing Patterns of Substance Use During the Coronavirus Pandemic: Self-Reported Use of Tobacco, Alcohol, Cannabis, and Other Drugs.

As in many other countries worldwide, the coronavirus pandemic prompted the implementation of an "intelligent lockdown" in the spring of 2020 in the Netherlands, including the closure of nightlife venues and cancellation of festivals. Such restrictions and social distancing could particularly affect people who use alcohol or other drugs in recreational settings and give rise to new challenges and additional needs in the field of addiction prevention and care. To monitor changes in substance use and provide services with practical directions for tailored prevention, an anonymous web survey was set up, targeting a convenience sample aged 16 years or older through various social media and other online channels.

Developing a new national MDMA policy: Results of a multi-decision multi-criterion decision analysis.

Background: Ecstasy (3,4-methylenedioxymethamphetamine (MDMA)) has a relatively low harm and low dependence liability but is scheduled on List I of the Dutch Opium Act ('hard drugs'). Concerns surrounding increasing MDMA-related criminality coupled with the possibly inappropriate scheduling of MDMA initiated a debate to revise the current Dutch ecstasy policy.

Methods: An interdisciplinary group of 18 experts on health, social harms and drug criminality and law enforcement reformulated the science-based Dutch MDMA policy using multi-decision multi-criterion decision analysis (MD-MCDA).
