Substance use disorders and sexual behavior

Introduction: Hardly any research exists on the relationship between substance use and sexual behaviors in patients with a substance use disorder. This study aimed to examine this relation by looking into perceived positive effects on sexual behavior, perceived negative effects and risky sexual behavior due to substance use in patient groups of users of alcohol, stimulants, sedatives and Gamma hydroxybutyrate (GHB). In addition, the current study aimed to address the question whether sexual behavior (e.g. number of sexual partners, sexualactivity) differs between these patient groups.Method: A total of 180 patients with a substance use disorder (i.e. alcohol, amphetamine, cannabis, cocaine, GHB and opiates) participated. A self-report questionnaire was administered with questions on substance use,sexual behaviors (e.g. sexual activity, masturbation, use of pornography) and statements about the perceived changes in sexual functioning and behavior under influence of the primary substance of abuse.Results: All four groups reported changes in sexual thoughts, feelings and behavior due to the use of their primary substance. More than half of the patients reported enhancements in sexual domains (i.e. sexual pleasure,sexual arousal, sexual behavior), but also decrements or risky behaviors and about a quarter stated that their sexual thoughts, feelings and behaviors were often associated with the use of their primary substance of abuse.Patients with a GHB use disorder reported the strongest relation between drug use and sexual behavior. Users of HB not only reported more enhancement in several sexual domains, but also less decline in sexual domains compared to the other patient groups and more risky behavior or more sexual activity than some of the other groups of patients.Conclusions: The results underline the importance of addressing the relationship between substance use and sexual behavior in treatment programs, as patients may be hesitant to stop their use of substances when they experience many positive effects in their sexual behavior. Future research directions are suggested.

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). 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.

Alcohol, drugs en opgroeien in Bunschoten

Voorstel voor rationeel MDMA-beleid

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.

Development of eHOME, a Mobile Instrument for Reporting, Monitoring, and Consulting Drug-Related Problems in Home Care

Home care patients often use many medications and are prone to drug-related problems (DRPs). For the management of problems related to drug use, home care could add to the multidisciplinary expertise of general practitioners (GPs) and pharmacists. The home care observation of medication-related problems by home care employees (HOME)-instrument is paper-based and assists home care workers in reporting potential DRPs. To facilitate the multiprofessional consultation, a digital report of DRPs from the HOME-instrument and digital monitoring and consulting of DRPs between home care and general practices and pharmacies is desired. The objective of this study was to develop an electronic HOME system (eHOME), a mobile version of the HOME-instrument that includes a monitoring and a consulting system for primary care.

Triangulating Amsterdam’s illicit stimulant use trends by wastewater analysis and recreational drug use monitoring

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.
