ACHTERGRONDMDMA (ecstasy) is een relatief veilige drug en induceert weinig afhankelijkheid, maar staat desondanks samen met andere harddrugs op lijst I van de Nederlandse Opiumwet. Bezorgdheid over de aan MDMA gerelateerde criminaliteit, het aantal gezondheidsincidenten en de mogelijk onterechte plaatsing van MDMA op lijst I hebben geleid tot een voortdurend debat over het huidige Nederlandse ecstasybeleid.DOELOntwikkeling van een rationeel MDMA-beleid waarbij men rekening houdt met alle aspecten gerelateerd aan de productie, verkoop en gebruik van MDMA.METHODEEen interdisciplinaire groep van 18 experts formuleerde een wetenschappelijk onderbouwd MDMA-beleid door de verwachte effecten van 95 beleidsopties op 25 uitkomsten te beoordelen, waaronder gezondheid, criminaliteit, rechtshandhaving en financiën. Het optimale beleidsmodel werd gevormd door een combinatie van 22 beleidsopties met de hoogste totaalscore op alle 25 uitkomsten. RESULTAAT Het optimale beleidsmodel bestond uit een vorm van gereguleerde productie en verkoop van MDMA, beter kwaliteitsbeheer van ecstasypillen en intensievere bestrijding van de MDMA-gerelateerde georganiseerde criminaliteit. Een dergelijk beleid zou leiden tot een kleine toename in de prevalentie van ecstasygebruik, maar met minder gezondheidsschade, minder MDMA-gerelateerde misdaad en minder milieuschade. Om de praktische uitvoerbaarheid en de politieke haalbaarheid te vergroten werd het optimale model enigszins aangepast.CONCLUSIEHet ontwikkelde optimale model biedt een politiek en maatschappelijk haalbare set van beleidsinstrumentopties, waarmee men plaatsing van MDMA op lijst I kan herzien, wat de schade van MDMA voor gebruikers en de samenleving kan verminderen. Voor de psychiatrie betekent het bevordering van therapeutisch onderzoek en minder hinder door nodeloze stigmatisering bij de behandeling van patiënten.--English:SUMMARYThe development of a rational national MDMA policy and itsrelevance for psychiatry.J.G.C. van Amsterdam, T. Nabben, G.-J. Peters, F. van Bakkum, J. Noijen, W. van den BrinkBackground MDMA (ecstasy) is a relatively safe drug and induces little dependence, but is nevertheless scheduled as a hard drug (Dutch Opium Act, List 1). Concerns about MDMA-related crime, health incidents and possible inappropriate listing of MDMA on List I have led to an ongoing debate about current Dutch ecstasy policy.Aim To develop a rational MDMA policy that takes into account all aspects related to production, sale and use ofMDMA.Method An interdisciplinary group of 18 experts formulates a science-based MDMA policy by assessing the expected effects of 95 policy options on 25 outcomes, including health, crime, law enforcement and finance. The optimal policy model consists of the combination of the 22 policy options with the highest total score on all 25 outcomes.Results The optimal policy model consisted of a form of regulated production and sale of MDMA, better qualitymanagement of ecstasy tablets and more intensive fight against MDMA-related organized crime. Such a policywould lead to a small increase in the prevalence of ecstasy use, but with less health damage, less MDMA-related crime, and less environmental damage. To increase practicality and political feasibility, the optimal model was slightly modified.Conclusion The developed optimal model offers a politically and socially feasible set of policy instrument options, with which the placement of MDMA on List I can be revised, thereby reducing the damage of MDMA to users and society. For psychiatry, it means promoting therapeutic research and less nuisance from unnecessary stigmatization in the treatment of patients.

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). The experts collectively formulated policy instruments and rated their effects on 25 outcome criteria, including health, criminality, law enforcement and financial issues, thematically grouped in six clusters.Results:The experts scored the effect of 22 policy instruments, each with between two and seven different mutually exclusive options, on 25 outcome criteria. The optimal policy model was defined by the set of 22 policy instrument options which gave the highest overall score on the 25 outcome criteria. Implementation of the optimal policy model, including regulated MDMA sales, decreases health harms, MDMA-related organised crime and environmental damage, as well as increases state revenues and quality of MDMA products and user information. This model was slightly modified to increase its political feasibility. Sensitivity analyses showed that the outcomes of the current MD-MCDA are robust and independent of variability in weight values.Conclusion:The present results provide a feasible and realistic set of policy instrument options to revise the legislation towards a rational MDMA policy that is likely to reduce both adverse (public) health risks and MDMA-related criminal burden.

De stuurgroep van de DenkTank MDMA-beleid publiceerde eind 2020 een rapport over de ontwikkeling van een rationeel MDMA-beleid. Het rapport is gebaseerd op een objectiverende wetenschappelijke benadering die zich losmaakt van ideologische politieke strijd. Uit een vergelijking van verschillende beleidsopties komt een Optimaal Model naar voren dat de minste schade blijkt op te leveren voor mens en maatschappij: regulering van de productie en van de aan- en verkoop van ecstasy, kwaliteitsbewaking, monitoring van het gebruik en een hardere aanpak van de misdaad. Minister van Justitie en Veiligheid Grapperhaus wijst dit model echter rigoureus af. Hij hamert op het gevaar van ‘ondermijning’ door de onderwereld van de legale bovenwereld. Wat pleit er voor en tegen invoering van het optimale model?

Drug consumption estimates are of relevance because of public health effects as well as associated criminal activities. Wastewater analysis of drug residues enables the estimation of drug consumption and drug markets. Short-term and long-term trends of cocaine, MDMA (ecstasy), amphetamine (speed) and methamphetamine (crystal meth), were studied for the city of Amsterdam. MDMA (+41%) and cocaine (+26%) showed significantly higher weekend vs. week consumption, while no differences were observed for the other drugs. The consumption of MDMA, cocaine, amphetamine and methamphetamine significantly increased between 2011 and 2019. Weekly trends emerging from wastewater analyses were supported by qualitative and quantitative data from a recreational drug use monitoring scheme. However, information collected in panel interviews within nightlife networks and surveys among visitors of pubs, clubs and festivals only partially reflected the long term increase in consumption as registered from wastewater analysis. Furthermore, methamphetamine use was not well presented in survey data, panel studies and test service samples, but could be monitored trough wastewater analysis. This illustrates that wastewater analysis can function as an early warning if use and user groups are small or difficult to reach trough other forms of research. All in all, this study illustrates that wastewater-based epidemiology is complementary to research among user groups, and vice versa. These different types of information enable to connect observed trends in total drug consumption to behaviour of users and the social context in which the use takes place as well as validate qualitative signals about (increased) consumption of psychoactive substances. Such a multi angular approach to map the illicit drug situation on local or regional scale can provide valuable information for public health.

Introduction: Ecstasy (MDMA) is a popular recreational drug, but its illegal production and trade in the Netherlands have developed into a serious public order and ecological problem which endanger and question the harm reduction approach of the Dutch ecstasy policy.Methods: The market characteristics, adverse health effects, risk profile, and link to criminal activity of ecstasy were reviewed.Results: Ecstasy is often used in combination with other substances (i.e. polydrug use). Compared to several other illicit drugs and alcohol, ecstasy has a very low abuse and dependence liability and, as yet, there is little evidence of long-term harm. A potential health risk associated with ecstasy is acute hyperthermia, however this occurs at an unknown incidence rate and seems to be more prevalent when ecstasy is consumed in combination with heavy exercise at high ambient temperatures or when used in combination with other substances, including alcohol. Organized crime related to the production and trafficking of ecstasy in the Netherlands is a growing problem.Conclusions: This review provides a science-based summary that can be used to assist the public and political debate surrounding future Dutch ecstasy policy to reduce ecstasy-related organized crime while maintaining the principle of harm reduction.

Background: Drug checking services (DCS) provide information about drug content and purity, alongside personalized feedback, to people who use drugs; however, the demographic and drug use characteristics of DCS clients are rarely reported. This paper describes these characteristics for clients of the Dutch DCS, the Drug Information and Monitoring System (DIMS). Methods: 1,530 participants completed a pen-and-paper questionnaire at one of eight participating DCS in the Netherlands in 2018. Results: The participants were mostly highly educated males in their twenties with no migration background. Experience with drugs prior to coming to the DCS was common. Only 0.7% indicated they had never used any of the twenty drugs studied. 93% of participants reported use of ecstasy or MDMA with an average of 6.3 years since first use. Conclusions: These results indicate that drug checking can be a valuable tool for public health services as it facilitates access to more difficult-to-reach communities who use drugs. It is unlikely that DCS encourage drug initiation, since almost all people who visit the Dutch DCS already report experience with drugs. However, DCS should be aware that their services might not be easily accessible or attractive to all demographic groups.

The last decades have seen an increase in the use of illicit recreational drugs. In this article we take a detailed look at the current state of normalisation of the three most popular illicit recreational drugs among Dutch university students in the Netherlands (MDMA/Ecstasy, cocaine and amphetamine) by zooming in on five established aspects of normalisation and expanding on one of those aspects: social accomodation, by adding a behavioural subcomponent (setting of use). For this purpose, we used quantitative data, obtained from four studies (2016, 2017, 2019 and 2020) among Dutch university students in a prototypical university city in the Netherlands (Groningen). Results show that three aspects of normalisation are clearly observable. The drugs are perceived as highly accessible, the last year prevalence of use is high, and experimenting, especially with MDMA/Ecstasy, is common. Accurate knowledge of the drugs and acceptance of occasional use, account in some measure for social accommodation. However, as students do not talk openly about their drug use with everyone in their environment, one cannot speak of cultural accommodation. Thus, although clear signs of normalisation of illicit recreational drugs, especially MDMA/Ecstasy, are observable among Dutch university students, there is no full-scale normalisation of these drugs.

Based on the results of two research projects from the Netherlands, this paper explores how street oriented persons adapt and use digital technologies by focusing on the changing commission of instrumental, economically motivated, street crime. Our findings show how social media are used by street offenders to facilitate or improve parts of the crime script of already existing criminal activities but also how street offenders are engaging in criminal activities not typically associated with the street, like phishing and fraud. Taken together, this paper documents how technology has permeated street life and contributed to the ‘hybridization’ of street offending in the Netherlands—i.e. offending that takes place in person and online, often at the same time.

In Antenne Gooi en Vechtstreek wordt sinds 2017 jaarlijks het middelengebruik onder jongeren en jongvolwassenen in de regio in kaart gebracht. Dit gebeurt op basis van een combinatie van kwalitatieve en kwantitatieve methoden. In 2024 verzamelden we informatie via (1) interviews met een panel van vier professionals waarin zij vertellen over de leefwereld, vrijetijdsbesteding en middelengebruik van risicojongeren; (2) een anonieme survey (vragenlijsten) over middelengebruik onder uitgaanders in 8 cafés in Hilversum, Bussum en Laren en op straat in het uitgaansgebied de Groest in Hilversum; en (3) analyse van testuitslagen van ruim driehonderd vrijwillig aangeleverde drugsmonsters bij de Hilversumse testservice, dit jaar aangevuld met een inventarisatie van drugsprijzen op basis van WhatsApp-menu’s van bezorgdiensten. Tezamen schetsen de verschillende bronnen een gedifferentieerd beeld van (trends in) gebruikspatronen en aanbod van alcohol, tabak, cannabis en andere drugs in Gooi en Vechtstreek.Door uitgaanders wordt fors gedronken, maar er is ook een groep die wil minderen of stoppen. Rokers wisselen sigaretten af met vapes. Er zijn zorgen over blowen bij risicojongeren. Gebruik van mdma-poeder neemt toe en er wordt vaker cocaïne gebruikt tijdens het uitgaan, maar gebruik van andere drugs stabiliseert of neemt af. De regionale drugsmarkt is laagdrempelig en bestaat voornamelijk uit bezorgdiensten die gebruikmaken van drugsmenu’s die via sociale media worden verspreid. Maar wat als 3-MMC wordt verkocht, blijkt dat vaak niet te zijn.
