INTRODUCTION: Social behaviour and network therapy involves an active participation of the practitioner in recruiting a supportive network to change the client's alcohol use. Despite achieving beneficial effects on alcohol consumption, its possible mechanisms of change are a relatively under-studied topic compared to those of other alcohol treatment interventions. This study aimed to explore therapist skills through which social behaviour and network therapy may achieve effects on alcohol consumption in comparison with motivational enhancement therapy...

INTRODUCTION: Attention deficit/hyperactivity disorder (ADHD) with co-occurring substance use disorder (SUD) is associated with poor treatment outcomes. Two randomized controlled trials, utilizing robust doses of stimulants, demonstrated a significant effect on treatment outcomes in patients with ADHD/SUD. This study aimed to investigate differences in executive functioning and explore the dose-dependent effect of OROS-methylphenidate (MPH) in patients with comorbid ADHD and amphetamine use disorder (ADHD+AMPH) and patients with ADHD only...

INTRODUCTION: Findings from general population studies are lacking in regard to the co-occurrence of alcohol and nicotine dependence in relation to later mortality. The aim of this study was to analyze potential interactions of risky alcohol drinking, tobacco smoking, alcohol and nicotine dependence, and time until the first cigarette is smoked in the morning after awakening in the prediction of mortality. METHODS: This study analyzed a random sample of the general population in Northern Germany, which comprised adults aged 18-64 years...

INTRODUCTION: Major depression, anxiety disorders, and post-traumatic stress disorder (PTSD) are among the most prevalent comorbid mental disorders in youth addiction treatment. Hence, screening for these internalizing disorders should be part of the standard routine at intake in substance use disorder treatment. We investigated the usefulness of the Depression, Anxiety and Stress Scale (DASS-21) as a screener for this purpose. METHODS: A nationally representative sample of 421 treatment-seeking youths aged 16-22 years with a primary cannabis, alcohol, cocaine, or amphetamine use disorder participated in the study...

INTRODUCTION: The phenomenon of craving and attention bias towards drug cues is theorized to operate cooperatively, owing to the principles of associative learning. In this context, the conditioned response to drug-related stimuli activates reward mechanisms within the brain, consequently inducing craving and fostering the underlying mechanisms that contribute to relapse in individuals with substance use disorders. Multiple studies have assessed the relationship between attention to substance-related cues and subjective craving through electroencephalography (EEG), but their findings have yet to be synthesized and examined...

INTRODUCTION: Elaborated intrusion theory suggests that imagery is central to craving; however, the possibility that cue-elicited multisensory imagery produces such urges has not been studied enough in the literature. Thus, we investigated the role of cue-elicited multisensory imagery on alcohol craving in individuals who are hazardous and social drinkers compared to mental and neutral imagery conditions. METHODS: In an online experiment, hazardous and social drinkers (N = 348) between 18 and 45 years old were randomised to multisensory, mental, and neutral imagery exposure...

INTRODUCTION: According to the literature, early initiation to cannabis use and a dependent pattern of use are important risk factors for the development of mental health disorders. However, there are few cohort studies which look at the development of mental health disorders associated with cannabis use among young people with cannabis use disorder (CUD). The aim of the study was to determine the cumulative incidence of mental health disorders and the risk of developing mental health disorders among minors who commenced treatment for CUD in Catalonia during 2015-2019...

INTRODUCTION: People with substance use disorder (SUD) may be at increased risk of COVID-19 infection. However, there is little evidence regarding the incidence of and determinants associated with infection in this group. The aims of the study were to determine the cumulative incidence of COVID-19 among people who sought treatment for heroin, cocaine, cannabis, and alcohol use disorder in Catalonia; to identify sociodemographic, substance, and clinical determinants associated with COVID-19 infection among SUD patients; and to compare the cumulative incidence of COVID-19 infection in the population with SUD with that of the general population...

INTRODUCTION: Opioid agonist treatment (OAT) is the most common and most effective treatment option for persons with opioid use disorders (OUD). In Germany, the prescription of OAT medications is regulated by the Narcotic Drugs Prescription Ordinance. With the introduction of restrictions to contain the SARS-CoV-2 virus, the German OAT regulations have been amended to ensure a legal continuation of OAT for people with OUD. In this study, we aimed to examine the use of the OAT regulations in practice, the experience made by physicians prescribing OAT medications, and their perspective on OAT regulations...

BACKGROUND: Generic drug legislation, i.e., simultaneously banning groups of drugs, has been introduced worldwide to counteract the trade and use of emerging "new psychoactive substances" (NPSs) more effectively. SUMMARY: The potential and de facto positive and negative effects of generic drug legislation have been described using an analysis based on documented evaluations of the experiences in the UK and Germany, supplemented with data from other publicly available sources...

INTRODUCTION: Training in addiction medicine and addiction psychology is essential to ensure the quality of treatment for patients with substance use disorders. Some earlier research has shown varying training between countries, but no comprehensive study of addiction training across Europe has been performed. The present study by the European Federation for Addiction Societies (EUFAS) aimed to fill this gap. METHODS: A Delphi process was used to develop a questionnaire on specialist training in addiction treatment in 24 European countries...

INTRODUCTION: Concomitant drug use is common among opioid-dependent patients in maintenance therapy. Attention deficit hyperactivity disorder (ADHD), a common comorbidity among opioid users, is associated with a higher risk of concomitant drug use. Earlier studies showed that methylphenidate (MPH) can reduce cocaine consumption among patients with ADHD. The use of MPH as an agonist-replacement or maintenance therapy in cocaine-dependent patients without ADHD is also common in Switzerland, despite a lack of supporting evidence...

INTRODUCTION: Previous research indicates a relation between craving and increased connectivity in the resting-state salience network. However, the link between cue-induced craving and connectivity in the salience network remains unclear. Further investigation is needed to understand the effect of sex on the relationship between cue-induced craving and the salience network. We investigated the role of sex in the association between the resting-state functional connectivity (RSFC) salience network and subjective cue-induced craving...

INTRODUCTION: Negative affect and anxiety frequently precede the onset of drug use in those with substance use disorder (SUD). Low self-esteem may increase the risk of relapse. We examined the short-term effects of exercise on affect, anxiety, and self-esteem in inpatients with poly-SUD. METHODS: This is a multicenter randomized control trial (RCT) with a crossover design. Thirty-eight inpatients (37.3 ± 6.4 years; 84% male) from three clinics participated in 45 min of soccer, circuit training, and control condition (psychoeducation) in a random order...

INTRODUCTION: Among people receiving current or previous opioid maintenance treatment (OMT), the leading cause of premature death is an opioid overdose. However, other causes of mortality remain high in this group. An understanding of causes of deaths across multiple settings can be useful in informing more comprehensive prevention responses. The aim of this study was to describe all non-overdose causes of death in three national cohorts (Czechia, Denmark, and Norway) among OMT patients and to explore associations of non-overdose mortality with age and gender...

INTRODUCTION: The standard screening instrument for alcohol problems in the current primary care, the Alcohol Use Disorder Identification Test-Consumption (AUDIT-C), contains a question about alcohol consumption "on a typical day." Since this is a term that leaves room for multiple interpretations and the differences between alcohol consumption on weekends and weekdays are not taken into account, this study examines whether the latter distinction improves the prediction validity of the screening instrument...

INTRODUCTION: Opioid agonist treatment (OAT) is the first-line treatment for opioid use disorder (OUD). Simultaneously, opioids are essential medicines in acute pain management. The literature is scarce on acute pain management in individuals with OUD, and guidelines are controversial for patients on OAT. We aimed at analyzing rescue analgesia in opioid-dependent individuals on OAT during hospitalization in the University Hospital Basel, Switzerland. METHODS: Patient hospital records were extracted from the database over 6 months (Jan-Jun) in 2015 and 2018...

INTRODUCTION: Internet gaming disorder (IGD) is an emerging condition within the field of behavioural addictions. IGD has been demonstrated to be highly comorbid with many other mental health disorders. Among these, substance use has been associated with IGD, and there are underlying similarities between behavioural addictions and substance use disorders. The main aims of the present study were (i) to investigate the association between high-risk gaming and substance use among young adults drawn from the general Italian population; and (ii) to explore the psychopathological correlates of high-risk gaming...

INTRODUCTION: This study offers insights into Dutch young people's expected social and personal consequences of ecstasy use. Substance use expectancies are assumed to be an essential component in explaining substance use behaviour and, therefore, the development of effective substance use prevention and treatment strategies. METHOD: Dutch young adults with an online interest in drug-related social media posts were targeted with an online survey about their use of alcohol and drugs...
