Is Europe facing an opioid epidemic: What does European monitoring data tell us?

This paper addresses the question of whether Europe is facing an opioid epidemic and utilizes data from the European monitoring system on opioid use, harms and availability, to help assess the situation. Data sources covering the last decade on overdose deaths, drug treatment entrants and drug-related emergencies suggest that the health burden associated with opioid use is mostly related to the consumption of heroin - and to a lesser extent diverted opioid substitution treatment medications - and that it is primarily affecting an ageing cohort of vulnerable users, with little evidence of an increase in initiation. While opioid-related deaths are currently at much lower levels than in the United States, they still represent a large preventable health burden with differences across EU countries. There is also increasing concern related to the high availability of heroin, illicitly produced synthetic opioids and diverted opioid pain medications on the European drugs market. Trends in the latter categories are poorly monitored and we may miss signs of emerging problems. Moreover, the economic recession following the COVID-19 pandemic has a potential to lead to resurgence in opioid use and harms. SIGNIFICANCE: This paper looks at data from the European monitoring system to address the question of whether Europe is facing an opioid epidemic. It reviews available health and supply side indicators, considering the limitations of each data source. A summary of the available evidence would suggest that while opioid-related deaths in Europe represent a large preventable health burden with differences across EU countries, Europe as a whole is not facing an opioid crisis of the size and nature seen in the US.

The use of multi-national web surveys for comparative analysis: Lessons from the European Web Survey on Drugs.

BACKGROUND: Most comparative drug policy analyses utilise measures of drug use, often from general population surveys (GPS). However, the limitations of GPS are well-recognised, including the small numbers of people who use illicit drugs sampled. Web surveys offer a potential solution to such issues. Therefore EMCDDA conducted a study to assess the potential for using such surveys to supplement information obtained from GPS. METHODS: The European Web Survey on Drugs (EWSD) asked about use of cannabis, amphetamines, cocaine and MDMA in 14 countries from 2016 to 2018. Each participant country translated the questionnaire as necessary and devised its own sampling strategy. Individuals aged 18+, resident in the participant country, who had used one or more of the drugs covered by the survey in the past 12 months were included in the analysis. Participation was anonymous and voluntary. RESULTS: More than 40,000 people completed the survey, with recruitment mostly through social media. Larger samples of users of all drug types than found in GPS were generally obtained. However, the respondent profiles differed markedly between countries, e.g. the proportion aged 18-24 ranged from 30% to 80%. The results relating to use showed both inter-country similarities and differences, e.g. mean daily amounts of cocaine used varied between countries but increases in amounts used with increased frequency of use were similar. Price data showed good external validity. CONCLUSION: Web surveys offer the possibility of collecting information from large numbers people who use illicit drugs quickly and cheaply and can fill important gaps in our knowledge of patterns of use, particularly by recreational users. However, they also have limitations. Standardising questionnaires and approaches to data cleaning and analysis facilitates comparisons between countries but obtaining comparable samples may be challenging. Multinational surveys need to balance standardisation of methods with responsiveness to differing country contexts; our collaborative model does this.

The drug situation in Europe: an overview of data available on illicit drugs and new psychoactive substances from European monitoring in 2015.

AIM: A central task for the European Monitoring Centre for Drugs and Drug Addiction (EMCDDA) is to produce an annual report of the latest data available on drug demand and drug supply in Europe. This paper is intended to facilitate a better understanding of, and easier access to, the main quantitative European level data sets available in 2015. METHODS: The European reporting system formally covers all 28 European Union (EU) Member States, Norway and Turkey and incorporates multiple indicators alongside an early warning system (EWS) on uncontrolled new psychoactive substances (NPS). While epidemiological information is based largely on registries, surveys and other routine data reported annually, the EWS collects case-based data on an ongoing basis. The 2015 reporting exercise is centred primarily on a set of standardized reporting tools. RESULTS: The most recent data provided by European countries are presented, including data on drug use, drug-related morbidity and mortality, treatment demand, drug markets and new psychoactive substances, with data tables provided and methodological information. A number of key results are highlighted for illustrative purposes. Drug prevalence estimates from national surveys since 2012 (last year prevalence of use among the 15-34 age band) range from 0.4% in Turkey to 22.1% in France for cannabis, from 0.2% in Greece and Romania to 4.2% in the United Kingdom for cocaine, from 0.1% in Italy and Turkey to 3% in the Czech Republic and the United Kingdom for ecstasy, and from 0.1% or less in Romania, Italy and Portugal to 2.5% in Estonia for amphetamine. Declining trends in new HIV detections among people who inject drugs are illustrated, in addition to presentation of a breakdown of NPS reported to the EU early warning system, which have risen exponentially from fewer than 20 a year between 2005 and 2008, to 101 reported in 2014. CONCLUSIONS: Structured information is now available on patterns and trends in drug consumption in Europe, which permits triangulation of data from different sources and consideration of methodological limitations. Opioid drugs continue to place a burden on the drug treatment system, although both new heroin entrants and injecting show declines. More than 450 new psychoactive substances are now monitored by the European early warning system with 31 new synthetic cathinones and 30 new synthetic cannabinoid receptor agonists notified in 2014.

Khat use and monitoring drug use in Europe: the current situation and issues for the future.

AIM OF THE STUDY: To review the information available on the use of khat (Catha edulis) in the EU, and to assess the future use of this drug and related substances. MATERIAL AND METHODS: Khat is not controlled by international law and it has not been systematically included in the list of illicit drugs monitored in the EU. The current principal source of information on khat use in Europe is the early-warning system set up to monitor new and emerging drugs. Further information was obtained from official national reports to the EMCDDA and from the scientific literature. RESULTS: Across Europe, the use of khat is low. Khat use is limited to countries with immigrant communities from countries where khat use is common (such as Ethiopia, Somalia and Kenya). Information on the prevalence of khat use in the general population is scarce. Data on seizures provide an insight on the situation, though these may be difficult to interpret. The most recent estimates suggest that Europe accounts for about 40% of the khat seized worldwide. CONCLUSION: The shortage of data on the use and patterns of use of khat in Europe does not allow an evaluation of the needs for health and social interventions in communities in which the drug is used. But seizures of the plant are increasing in the EU, and more synthetic derivatives of the pharmacologically active ingredients of the plant (cathine and cathinone) are appearing on the market. Some of these, like mephedrone, have significant potential for future diffusion, and are likely to play a greater role on the European drug scene of the future.
