Background:
the role of medications for alcohol use disorder (MAUD) in patients with cirrhosis is not well established. Evidence on the efficacy and safety of these drugs in these patients is scarce. Approach & results: we performed a systematic review and meta-analysis according to PRISMA guidelines on the efficacy of MAUD in patients with cirrho...
Background:
Alcohol use can cause harm not only to the person who consumes it but also to others. Prior research has found that these alcohol-attributable harms to others differ across socioeconomic groups, though several findings have been contradictory. The aim of this contribution was to study the role of individual-level and population-level i...
Background:
Using data from 33 European countries (including all EU member states), this study aimed to 1) estimate the prevalence of unrecorded alcohol use among past-week alcohol users, 2) describe how unrecorded alcohol use is associated with drinking patterns, and 3) estimate the contribution of unrecorded alcohol to the total amount of alcoho...
Background. For alcohol, regulating availability is an effective way to reduce consumption and harm. Similarly, the higher availability of medical cannabis dispensaries has been linked to increased cannabis consumption and harm. For recreational cannabis markets, such a link is suspected but still poorly understood.
Methods: A systematic literature...
Background: Alcohol’s detrimental health effects do not affect everyone equally but accumulate in people with low socioeconomic status (SES). Using data from the 2021 Standard European Alcohol Survey, we explore gender- and SES-specific consumption patterns, and COVID-19 related changes in consumption across Europe. Methods: Cross-sectional populat...
Objectives:
Cannabis use quantities are relevant for determining cannabis-related harms. This research aims to provide an overview of the available methods to assess quantities through self-report.
Methods:
A rapid review of various strategies to collect information on cannabis use quantities through self-report. Two independent literature searc...
Lifetime prevalence of cannabis use is estimated 192 million adults worldwide (2017) and has increased by 16% in the last decade. However, data on quantity and frequency of use that can lead to harm is lacking. We have developed a survey to assess patterns of cannabis use and related harms in a sample of cannabis users. This paper focuses on evalua...
BACKGROUND
The lockdown measures introduced during the COVID-19 pandemic were a catalyst for rapid digitalisation of services in the field of substance use and substance use disorders. This highlights a need to backcast and co-create a future where digital tools for addressing substance use are optimally developed and used.
OBJECTIVE
This paper re...
Background:
A significant proportion of people attending Primary Care (PC) have anxiety-depressive symptoms and work-related burnout compounded by a lack of resources to meet their needs. The COVID-19 pandemic has exacerbated this problem and digital tools have been proposed as a solution.
Objective:
We present the development, feasibility, and...
The aim of the current study is to assess if the patterns of use, socio-demographic characteristics, and use of other drugs differ among people who only use cannabis and those that use synthetic cannabinoids. Data from the second wave of the European Web Survey on Drugs, a web-based cross-sectional survey from 10 different European countries includ...
No- and low-alcohol drinks (NoLo) have been proposed as a potential way forward for the reduction in the alcohol burden of disease. So far, there is scarce synthesized evidence on the effects of these products on people with alcohol use disorder (AUD), or with a heavy or high-risk
drinking pattern. The aim of the present study is to systematically...
Background: Effective interventions exist for heavy drinking and depression but to date there has been limited translation into routine practice in global health systems. This evidence-to-practice gap is particularly evident in low- and middle-income countries. The international SCALA project (Scale-up of Prevention and Management of Alcohol Use Di...
Background
Initial results from the SCALA study demonstrated that training primary health care providers is an effective implementation strategy to increase alcohol screening in Colombia, Mexico and Peru, but did not show evidence of superior performance for the standard compared to the shorter training arm. This paper elaborates on those outcomes...

A heart transplantation (HT) is performed when a patient’s heart health has been severely compromised. However, the health care needs of a patient throughout the transplantation process are also significant. In order to investigate these postoperative heart transplant challenges, this study has two objectives: to find which psychosocial and psychia...
Background:
Cannabis is one of the most used drugs worldwide. There is no gold standard treatment for cannabis use disorder (CUD). Motivational interviewing (MI) has shown efficacy in some substance use disorders. Therefore, a systematic review was conducted to assess the effectiveness of MI in CUD.
Methods:
Randomized controlled trials or open-...
Evidence suggests that changes in alcohol consumption during the first months of the COVID-19 pandemic were unevenly distributed over consumer groups. We investigated possible inter-country differences in how changes in alcohol consumption are contingent on initial consumption (before or at the start of the pandemic), and how changes in consumption...
Background
The lack of an agreed international minimum approach to measuring cannabis use hinders the integration of multidisciplinary evidence on the psychosocial, neurocognitive, clinical and public health consequences of cannabis use.
Methods

Background : While primary health care-based prevention and management of heavy drinking is clinically effective and cost-effective, it remains poorly implemented in routine practice. Systematic reviews and multi-country studies have demonstrated the ability of training and support programmes for healthcare professionals to increase primary health...
Introduction: Reduced drinking has been debated as a treatment goal for heavy drinking alcohol dependent patients, in whom treatment based on abstinence is not always an option. Nalmefene was the first drug approved by the European Medicines Agency (2013) with the indication of reduced drinking in high drinking risk level alcohol dependent patients...
BACKGROUND
In the EU, approximately 165 million people suffer from mental health disorders, namely anxiety, mood disorders, and substance abuse. These mental health disorders have resulted in both direct and indirect global economic costs estimated at US $2.5 trillion in 2010, with the indirect costs (USD $ 1.7 trillion) being significantly higher...
