Drugs: Drug Markets
Drug Markets
Since the 1990s, the Ministry of Health enabled the testing of illicit drugs for drug users to prevent serious health hazards associated with unexpected dangerous substances. This illicit drug testing system is called the Drugs Information and Monitoring System (DIMS); DIMS is a national network of testing facilities that furthermore aims at gaining an insight into the market of controlled substances. DIMS is embedded within the Trimbos Institute and is funded by the Ministry of Health (VWS). DIMS also runs the THC monitor (by analyzing cannabis samples purchased in randomly selected coffee shops on a yearly basis), and since 2012, DIMS also hosts the Monitor New Drugs, which focuses specifically on New Psychoactive Substances.
More about DIMS
THC monitor
Many of the cannabis products sold in coffee shops originate from Dutch-grown marijuana, known in Dutch as 'nederwiet'. On behalf of the Ministry of Health, Welfare, and Sport, the THC Monitor investigates the potency of cannabis products sold in coffee shops in the Netherlands.

Monitor of New Drugs
The Monitor of New Drugs (MND) assesses the presence of new (mostly unregulated) psychoactive substances in the DIMS system, along with data from the National Forensic Institute and the Customs Laboratory. The MND reports directly to the Ministry of Health, Welfare, and Sport, as well as to the Office of the Coordination, Assessment and Monitoring of New Drugs.

Monitor Drug-related Incidents
The Monitor Drug-related Incidents collects information on presentations with drug-related acute toxicities at four medical services and in eight regions of the Netherlands to provide an indicative base for monitoring.

Other monitoring studies
- The Dutch National School Survey is a national research effort regarding the use of tobacco, alcohol, drugs, and the internet among adolescents.
- The European School Survey Project on Alcohol and Other Drugs (ESPAD) is a collaborative effort of independent research teams in more than forty European countries and the largest cross-national research project on adolescent substance use in the world.
- The Health Behavior in School-aged Children (HBSC) survey collects data every four years on 11-, 13- and 15-year-old boys' and girls' health and well-being, social environments, and health behaviors. HBSC includes 44 countries and regions across Europe and North America.
Red Alert
When substances are found in drugs that pose an acute danger to public health, for example contaminated XTC pills or pills with an extremely high dose of MDMA, a Red Alert procedure is started. In case of a Red Alert, health authorities and the media are informed. The public is informed via news items, posters and flyers at parties. The goal of a Red Alert is to inform as many people as possible and keep the number of incidents as small as possible.
