Addiction is a chronic yet treatable disorder. Patterns of addiction, whether substance related or behavioural, vary among countries and regions. Addiction medicine practice and approaches used in management are not only different from one country to another but are influenced by other factors, including environmental ones. The COVID-19 pandemic is one of the major environmental changes that had an impact on addiction. In this editorial, light will be shed on three articles covering recent updates in addiction medicine, ranging from types of substances and service provision to inclusion of gaming disorder in ICD-11.

As defined by the World Health Organization, the Eastern Mediterranean Region (EMR), given its special geopolitical situation and internal/external conflicts, faces an increase in illegal activities such as drug production and trafficking, highlighting the need for a comprehensive understanding of the substance use situation. On the basis of a review of published papers between 2015 and 2021 we briefly review substance use in the EMR with special focus on the emerging drugs pertinent to this region, namely tramadol, captagon and khat.

The World Health Organization (WHO) has added gaming disorder to ICD-11 as a clinical condition associated with distress or interference with personal functioning. This inclusion leads to clinical and public health benefits, such as harmonising terminology, offering clinical landmarks and improving monitoring capabilities and data comparability. Training health professionals to identify and manage gaming disorder is a key challenge for countries. In the present paper we compiled opinions from different countries around the globe on their state of preparedness and needs to tackle this issue. The global views on the topic feed arguments for developing an evidence-based and cross-cultural training tool for gaming disorder management by health professionals.

The COVID-19 pandemic has significantly affected treatment services for people with substance use disorders (SUDs). Based on the perspectives of service providers from eight countries, we discuss the impact of the pandemic on SUD treatment services. Although many countries quickly adapted in provision of harm reduction services by changes in policy and service delivery, some went into a forced abstinence-based strategy. Similarly, disruption of abstinence-based approaches such as therapeutic communities has been reported. Global awareness is crucial for responsible management of SUDs during the pandemic, and the development of international health policy guidelines is an urgent need in this area.

The article provides a brief overview of the legislation governing involuntary admissions to psychiatric hospitals in Luxembourg. The legislation was completely overhauled in 2009 and several human rights principles are enshrined into it. Emphasis is placed on voluntary, community-based treatment, and where compulsory treatment is required, it uses the least restrictive treatment option. Mentally ill offenders are dealt with through separate specialist legislation. Young people under the age of 18 are often detained using family law.

We describe mental health services in Luxembourg and how they have evolved over the past 50 years. Health services in Luxembourg are provided through a social health insurance-based system and mental health services are no exception. Additional services are offered through mixed-funding avenues drawing on social care budgets in the main. Luxembourg is closely connected with neighbouring countries, where a large proportion of its workforce live. No run-through medical training exists and the entire medical workforce, including psychiatrists, have trained in other countries. This is reflected in a rich but often non-uniform approach to the provision of psychiatric care.

This report describes a pilot project which involved undergraduate medical students’ clinical competence in psychiatry assessed through objective structured clinical examinations for the first time in Zimbabwe. The pilot describes how gaps in medical education can be addressed by collaborative partnerships that allow sharing of knowledge by local institutions and international experts.
