Omzetberekeningen van synthetische-drugsproductie in Nederland

Tijdschrift Tijdschrift voor Criminologie, Aflevering 2 2021
Trefwoorden Drug trafficking, Organized Crime, Turnover Estimates
Auteurs Judith van Valkenhoef en Pieter Tops
SamenvattingAuteursinformatie

    In 2018 we published a report on the production of synthetic drugs in the Netherlands. We calculated the turnover of synthetic drugs produced in the Netherlands in 2017; we estimated it to be at least 18.9 billion euro (worldwide, street prices). In this article, we will discuss how these calculations were executed and on which assumptions they were based. We describe the responses to these calculations, nationally and internationally. Finally, we describe problems we encountered when performing a repetition of the calculations for the year 2018. Our central message is: drug turnover calculations can be an important addition to scientific and political discussions about illicit drugs, provided they are presented in a transparent way and acknowledging the inherent limitations of these calculations.

Open heimelijke netwerken in de Nederlandstalige georganiseerde synthetische-drugscriminaliteit

Tijdschrift Tijdschrift voor Criminologie, Aflevering 2 2021
Trefwoorden synthetic drugs, poly-drug trafficking, organized crime, encrypted communication data, social network analysis
Auteurs Irma Vermeulen, Melvin Soudijn en Wouter van der Leest
SamenvattingAuteursinformatie

    In recent years, the authorities have dismantled several encrypted phone providers. These providers stored millions of messages about covert activities that were overtly exchanged between criminals. This type of communication offers a unique insight into serious organized crime and the people involved. Based on one such intercepted encrypted phone network, called PGP-Safe, we carried out a social network analysis on the Dutch-speaking synthetic drug market. Three findings stand out. Firstly, three-quarters of all accounts (N=4,158) are interconnected in a giant component, resulting in a criminal small-world effect. Secondly, the network appears to be robust. As a consequence, the removal of central accounts will hardly have any impact on the network as a whole. Thirdly, the majority of the accounts within the synthetic drug market is involved in poly-drug trafficking. The Dutch synthetic drug market is much more closely intertwined with other drug markets than is commonly known.

Het grensgebied als waterbed voor drugscriminaliteit?

Tijdschrift Tijdschrift voor Criminologie, Aflevering 2 2021
Trefwoorden displacement, cross-border crime, organized drug crime, policy effectiveness, balloon effect
Auteurs Rik Ceulen, Stephan Van Nimwegen en Toine Spapens
SamenvattingAuteursinformatie

    This paper concerns the question whether in the period 2011-2017 displacement effects occurred from the Netherlands to Belgium in the context of synthetic drugs production, cannabis cultivation, and retail of illicit drugs, and if so, how these may be explained. We conclude that displacement took place in modi operandi of retail drug dealers. This is explained foremost by the policy of banning non-residents from Dutch coffeeshops in border region municipalities. Dealers and traffickers responded by switching to local distribution in Belgium as well as deliveries by drug couriers. The synthetic drugs and cannabis cultivation markets show minor changes in modi operandi, but no changes occurred in choosing production locations. Displacement effects in the context of organized drug crime must be explained from a range of factors. Reality is therefore more complex than assuming that government interventions are the main cause of a balloon effect.

De doorvoer van cocaïne via Nederland

Tijdschrift Tijdschrift voor Criminologie, Aflevering 2 2021
Trefwoorden cocaine trafficking, ping-pong trade, poly-drug trafficking, qualitative social network analysis, transnational networks of networks
Auteurs Vanessa Dirksen, Wouter van der Leest en Irma Vermeulen
SamenvattingAuteursinformatie

    This article describes traits of the hitherto underexposed transit trade of cocaine via the Netherlands, based on a qualitative social network analysis of a diversity of data. Research findings show that the transit trade via the Netherlands is dominated by poly-drug trafficking. It is noteworthy that streams of predominantly mono-drugs are entering the Netherlands, while mainly streams of poly-drugs are leaving the country. Our research furthermore shows that cocaine intended for European markets may be transited via the Netherlands to European countries to which the cocaine was initially imported. This is what we refer to as ping-pong trade. Another characteristic of the transit trade of cocaine via the Netherlands is that the actors involved, mainly coordinate parts of the cocaine supply chain. Although different groups within the cocaine distribution chain collaborate, this does not necessarily mean they actually know each other. Taken together, the organization of the distributive trade of cocaine is in this article positioned as an interdependent transnational network of networks (NoN). We suggest that future research into the transit trade of cocaine should apply such a transnational NoN perspective to fully grasp the interdependence of the micro and meso levels of the trade and, in so doing, ultimately comprehend the effect this may have on the macro level.

Georganiseerde misdaad in de 21ste eeuw

Tijdschrift Tijdschrift voor Criminologie, Aflevering 2 2016
Trefwoorden organized crime
Auteurs Prof. dr. Toine Spapens, Prof. dr. Emile Kolthoff en Prof. dr. Wouter Stol
SamenvattingAuteursinformatie

    In the past decades, organised crime internationalised rapidly as a result of increasing mobility and ‘open’ borders. At the same time developments in information and communication technology have led to modernisation of existing types of crime and the introduction of novel ones. Finally, criminals have benefited from increasingly diversified migration streams. In the Netherlands and Belgium, organised crime appeared on the agenda in the 1990s. For a long time emphasis was on ‘trade crimes’ i.e. trafficking in drugs and humans, as well as human smuggling, followed by the production of synthetic drugs and cannabis. More recently the Low Countries are confronted by more visible manifestations of organised crime, for example rapid growth of outlaw motorcycle gangs. Criminals also try to utilise their capital to invest in businesses and real estate and to influence local politics.

Roesmiddelen en regulering: oude wijn in nieuwe regels?

Inleiding

Tijdschrift Tijdschrift over Cultuur & Criminaliteit, Aflevering 2 2016
Trefwoorden pleasurable substances, regulation, cannabis, war on drugs
Auteurs Prof. dr. Tom Decorte en Dr. Damián Zaitch
SamenvattingAuteursinformatie

    In contrast with the critical, innovative ideas developed between the 1960s and the 1980s regarding the way we deal with illegal drugs in our societies, the current dominant approaches frame the issue of drugs as a matter of crime, public order, and control. Pleasurable substances have always existed and always will, and so the efforts to cope with them. However, we witness today remarkable developments at local, national and international levels in the fields of drug policies (on cannabis for example), drug trafficking (new routes, new actors) and drug use (new substances, new drug cultures), all of which deserve our attention and push us to think beyond the repressive paradigm. This contribution, which also serves as an introduction for this special issue of ToCC on drugs, aims to present an overview of the main developments taking place, and challenges ahead, within the three above-mentioned fields. There are new markets and trends in the use of legal and illegal pleasurable substances, particularly regarding synthetic drugs (amphetamines, methamphetamines and new psychoactive substances or NPS), tobacco and alcohol. Illegal drugs are supplied from changing countries and through new routes, while retailing increasingly takes place through the so-called cryptomarkets (online). Effective policies are rendered impossible by the fundamental repression paradox: the more intensive and effective the repression, the larger the profits of drug traffickers and the balloon effects (displacement). Despite the harms and negative effects of repressive policies have extensively been documented, a societal debate towards the regulation of illegal drugs is hindered by the use of false dichotomies or presuppositions, by the use of ethical or moral appeals, or by lack of political will. Also the debate in the media is static, superficial and full of clichés. Scientific research on drugs also follows specific agendas and it is focussed on particular aspects of the problem. Changes to end the ‘war on drugs’, certainly regarding cannabis, are however underway in many places at local and national level (Uruguay, Canada, US, Spain, etc.), this despite UN bureaucracies and international conventions that fiercely resist those changes.

Schuldattributie en genderstereotypen in nieuwsberichtgeving en onlinediscussies

Tijdschrift Tijdschrift voor Criminologie, Aflevering 4 2010
Trefwoorden Gender, Verkrachtigsdrugs, Slachtoffers, Online fora
Auteurs Peter Burger en Gabry Vanderveen
SamenvattingAuteursinformatie

    Rape drugs (or drink spiking) discourse reflects gender stereotypes in a much more differentiated way than previous studies suppose. Quantitative and qualitative analysis of news items and online discussions proved stereotypes of ideal female victims and male perpetrators to be most prominent in news media. Postings to online bulletin boards were more skeptical about the alleged victims’ innocence and truthfulness. Studies in this area that focus on news media and institutional discourse overestimate the predominance of the ideal victim stereotype. In order to correct this bias, the authors urge criminologists to be more attentive to the relevance and power of informal crime stories and discussions, particularly those appearing in social media.

Britse criminelen in Nederland en Nederlandse criminelen in Spanje

Tijdschrift Tijdschrift voor Criminologie, Aflevering 2 2010
Trefwoorden drugshandel, Internationale criminaliteit, Spanje, Verenigd Koninkrijk
Auteurs Dr. Melvin Soudijn en Dr. Sander Huisman
SamenvattingAuteursinformatie

    This article focuses on migration with criminal motives. Two specific groups are discussed, British migrants in the Netherlands and Dutch migrants in Spain. Little is written on criminal migration motives in combination with Western subjects. On the other hand, investigative authorities have first-hand knowledge on this matter. An analysis of 25 closed case files shows that within these two groups of migrants, some people are heavily involved in the international drugs trade. Although their numbers are small, their function is important. Through their actions it becomes possible for certain cities or areas to evolve into international criminal drug marketplaces. There are also some differences between British and Dutch criminals abroad. British criminals are often involved as brokers. They broker drugs for third parties in Great Britain. Their stay in the Netherlands seems temporarily. They do not invest in the economy or buy property. Conversely, Dutch criminals in Spain could be described as leaders of organized crime groups. They invest in Spain by buying companies and property.
