Predictors of effective therapy among individuals with Cannabis Use Disorder: a review of the literature.

Treatment demand for Cannabis Use Disorder (CUD) has increased in the past decade in almost all European countries, and CUD is currently the most common reason for first-time drug-related treatment admission in the European Union. Even though several therapeutic approaches have been shown to benefit individuals with CUD, there is a lack of knowledge regarding factors associated with effective therapy and the underlying mechanisms of change among individuals with CUD presenting for treatment. The aim of the present paper was to review current knowledge on factors that have been shown to contribute to positive outcomes in CUD treatment. A scoping methodology was used, focusing on empirically evaluated studies that used defined, cannabis-related outcome measures. In eligible studies, factors of investigation were categorized as either 'mediators', i.e., treatment-related factors associated with the processes or mechanisms through which patients benefit from therapy, or 'moderators' which are patient-related characteristics that predict his/her odds to benefit from treatment or patient-related (i.e., moderators). Factors categorized as mediators were then classified 'specific factors' if they were related to a certain technique or treatment modality or 'common factors' if they were assessed beyond treatment modalities. Findings suggest that in CUD treatment, specific mediators include treatment duration, addressing motivation to change, acquiring coping skills, enhancing self-efficacy, and integrating several therapeutic components. Common mediators include therapeutic alliance, empathy, expectations and cultural adaptation. Moderators in CUD treatment include sex, ethnicity, age-related factors and comorbid disorders.

Cannabis-related treatment demand at the eve of German cannabis legalization - a 20-years trend analysis.

Post-2000, the prevalence of cannabis consumption has been rising internationally. This paper investigates whether cannabis-related treatment demand in German outpatient addiction care facilities (OACFs) has been following this trend. Treatment demand related to cannabis use disorder (CUD) for the period 2001 to 2021 was investigated using data from the nation-wide standardized German Addiction Care Statistical Service. Analyses covered all and first-time treatment admissions, demographics, and treatment outcomes. We identified years with significant changes in slope or direction of trends through joinpoint regression. Trends within the CUD client population were contrasted with trends among the entire OACF client population. CUD is the second-most common cause for OACF admissions in Germany. Between 2001 and 2021, the share of CUD-related cases among total OACF caseload increased from 7.1 to 19.9%, whereby the share of first-time treatment admissions declined from 79.6 to 55.6%. The share of CUD client population > 35 years almost tripled from 6.0 to 17.4%, that of female client population rose from 15.6 to 18.1%. From 2001 to 2007, the share of CUD-related treatments completed with improved symptomatology increased from 54.7 to 65.6%, followed by a marginal decline. CUD-related treatment demand is growing in Germany's OACFs, involving a client population that is increasingly older and more experienced with the addiction care system. As current intervention programmes mainly target adolescents and young adults who have been consuming cannabis only for a short time, adapting service offers to the changing client profiles appears paramount to improve treatment effectiveness.

Predictors of changes in marijuana consumption in Germany during the covid-19 pandemic.

During the Covid-19 pandemic Germany experienced its first increase in the proportion of heavy cannabis users since 1995. With the expected nationwide decriminalization of cannabis before 2025, we investigate the potential causes for that increase. Data were from the 2021 European Web Survey on Drugs (EWSD) including 762 12-month marijuana users from Germany (72.9% male, mean age = 29.5 years). Both heavy and regular cannabis consumers reported an increase in marijuana consumption during the pandemic, with infrequent users reporting a decrease. Using multinomial logistic regression, we found younger individuals (OR = 0.95 [95% CI = 0.92, 0.98]) and those not pursuing or completing higher education (OR = 1.86 [1.23, 2.81]) had increased use. Additionally, using cannabis to self-medicate (OR = 2.79 [1.56, 4.99]) and purchasing marijuana (OR = 2.26 [1.35, 3.77]) was associated with increased use. We found, relative to infrequent users, both regular (OR = 4.00 [2.39, 6.72]) and notably heavy users (OR = 31.17 [12.10, 80.32]) were more likely to use cannabis to self-medicate. Both regular (OR = 4.09 [2.47, 6.77]) and especially heavy users (OR = 13.53 [6.74, 27.16]) were also more likely to purchase marijuana. Heavy users were also more likely to be past 30-day tobacco users (OR = 5.92 [2.81, 12.45]). We identified the self-reported motivation of using cannabis to self-medicate as well as act of purchasing marijuana as having the strongest relation to being a heavy user and increasing marijuana use during the Covid-19 pandemic.

Short-term effectiveness of the national German quitline for smoking cessation: results of a randomized controlled trial.

BACKGROUND: The objective of the present study was to examine the short-term effectiveness of the national German quitline for smoking cessation. METHODS: A parallel-group, two-arm, superiority, randomized controlled trial with data collection at baseline and post-intervention (three months from baseline) was conducted. Individuals were randomized to either the intervention group, receiving up to six telephone counselling calls, or the control group, receiving an active control intervention (self-help brochure). The primary outcome was the seven-day point prevalence abstinence at post-assessment. Secondary outcomes included changes in smoking-related cognitions and coping strategies from pre- to post-assessment, the perceived effectiveness of intervention components, and the satisfaction with the intervention. RESULTS: A total of n = 905 adult daily smokers were assigned to either the intervention group (n = 477) or the control group (n = 428). Intention-to-treat analyses demonstrated that individuals allocated to the telephone counselling condition were more likely to achieve seven-day point prevalence abstinence at post-assessment compared to those allocated to the self-help brochure condition (41.1% vs. 23.1%; OR = 2.3, 95% CI [1.7, 3.1]). Participants who received the allocated intervention in both study groups displayed significant improvements in smoking-related cognitions and coping strategies with the intervention group showing greater enhancements than the control group. This pattern was also found regarding the perceived effectiveness of intervention components and the satisfaction with the intervention. CONCLUSION: The present study provides first empirical evidence on the short-term effectiveness of the national German quitline for smoking cessation, highlighting its potential as an effective public health intervention to reduce the burden of disease associated with smoking. TRIAL REGISTRATION: This study is registered in the German Clinical Trials Register (DRKS00025343). Date of registration: 2021/06/07.

Recommendations for Reducing the Risk of Cannabis Use-Related Adverse Psychosis Outcomes: A Public Mental Health-Oriented Evidence Review.

Objective: Cannabis use is increasingly normalized; psychosis is a major adverse health outcome. We reviewed evidence on cannabis use-related risk factors for psychosis outcomes at different stages toward recommendations for risk reduction by individuals involved in cannabis use. Methods: We searched primary databases for pertinent literature/data 2016 onward, principally relying on reviews and high-quality studies which were narratively summarized and quality-graded; recommendations were developed by international expert consensus. Results: Genetic risks, and mental health/substance use problem histories elevate the risks for cannabis-related psychosis. Early age-of-use-onset, frequency-of-use, product composition (i.e., THC potency), use mode and other substance co-use all influence psychosis risks; the protective effects of CBD are uncertain. Continuous cannabis use may adversely affect psychosis-related treatment and medication effects. Risk factor combinations further amplify the odds of adverse psychosis outcomes. Conclusions: Reductions in the identified cannabis-related risks factors-short of abstinence-may decrease risks of related adverse psychosis outcomes, and thereby protect cannabis users' health.

Effectiveness of the national German quitline for smoking cessation: study protocol of a randomized controlled trial.

BACKGROUND: Despite the decline in cigarette smoking prevalence during nearly the past two decades, tobacco use is still widespread in the German adult population, accounting for 125,000 deaths each year and causing tremendous social costs. To accelerate the reduction in tobacco smoking prevalence, evidence-based smoking cessation methods are pivotal to a national tobacco control strategy. The present study aims to evaluate the effectiveness of the national German Smokers Quitline offering cessation support to smokers. METHODS: A total sample of 910 daily smokers, who are motivated to quit, will be recruited via an online access panel and randomly assigned to either the intervention (telephone counselling) or control condition. In the intervention group, participants will receive up to six proactive phone calls during an intervention period of approximately six weeks. The provided treatment will combine the principles of motivational interviewing and those of the cognitive behavioural approach to treating substance use. Participants in the control condition will receive a self-help brochure to support smoking cessation. Data collection will take place at baseline as well as three (post assessment) and twelve months (follow-up assessment) after baseline assessment. Primary outcome measures will include the seven-day point prevalence abstinence at 3-month and 12-month assessments as well as prolonged abstinence (abstinence over the 12 month period). Secondary outcome measures will include a change in smoking-related cognitions and coping strategies among all participants. Among non-abstainers, treatment success indicators such as a reduction in number of cigarettes smoked per day and changes in the number and duration of quit attempts after intervention start will be assessed. It is expected that after both three and twelve months, smoking cessation rates will be higher in the telephone counselling condition compared to the control condition. DISCUSSION: The results will provide insights into the effectiveness of proactive telephone counselling by the national German Smokers Quitline. TRIAL REGISTRATION: The protocol for this study is registered with the German Clinical Trials Register: DRKS00025343, Date of registration: 2021/06/07, https://www.drks.de/drks_web/setLocale_EN.do.

Psychosocial and pharmacological treatments for cannabis use disorder and mental health comorbidities: a narrative review.

Cannabis is the most widely used illicit drug worldwide, and it is estimated that up to 30% of people who use cannabis will develop a cannabis use disorder (CUD). Demand for treatment of CUD is increasing in almost every region of the world and cannabis use is highly comorbid with mental disorders, where sustained use can reduce treatment compliance and increase risk of relapse. In this narrative review, we outline evidence for psychosocial and pharmacological treatment strategies for CUD, both alone and when comorbid with psychosis, anxiety or depression. Psychosocial treatments such as cognitive behavioural therapy, motivational enhancement therapy and contingency management are currently the most effective strategy for treating CUD but are of limited benefit when comorbid with psychosis. Pharmacological treatments targeting the endocannabinoid system have the potential to reduce cannabis withdrawal and cannabis use in CUD. Mental health comorbidities including anxiety, depression and psychosis hinder effective treatment and should be addressed in treatment provision and clinical decision making to reduce the global burden of CUDs. Antipsychotic medication may decrease cannabis use and cannabis craving as well as psychotic symptoms in patients with CUD and psychosis. Targeted treatments for anxiety and depression when comorbid with CUD are feasible.

Classical blood biomarkers identify patients with higher risk for relapse 6 months after alcohol withdrawal treatment.

This naturalistic study among patients with alcohol dependence examined whether routine blood biomarkers could help to identify patients with high risk for relapse after withdrawal treatment. In a longitudinal study with 6-month follow-up among 133 patients with alcohol dependence who received inpatient alcohol withdrawal treatment, we investigated the usefulness of routine blood biomarkers and clinical and sociodemographic factors for potential outcome prediction and risk stratification. Baseline routine blood biomarkers (gamma-glutamyl transferase [GGT], alanine aminotransferase [ALT/GPT], aspartate aminotransferase [AST/GOT], mean cell volume of erythrocytes [MCV]), and clinical and sociodemographic characteristics were recorded at admission. Standardized 6 months' follow-up assessed outcome variables continuous abstinence, days of continuous abstinence, daily alcohol consumption and current abstinence. The combined threshold criterion of an AST:ALT ratio > 1.00 and MCV > 90.0 fl helped to identify high-risk patients. They had lower abstinence rates (P = 0.001), higher rates of daily alcohol consumption (P < 0.001) and shorter periods of continuous abstinence (P = 0.027) compared with low-risk patients who did not meet the threshold criterion. Regression analysis confirmed our hypothesis that the combination criterion is an individual baseline variable that significantly predicted parts of the respective outcome variances. Routinely assessed indirect alcohol biomarkers help to identify patients with high risk for relapse after alcohol withdrawal treatment. Clinical decision algorithms to identify patients with high risk for relapse after alcohol withdrawal treatment could include classical blood biomarkers in addition to clinical and sociodemographic items.

[Psychosocial support during the COVID-19 pandemic: interdisciplinary concept of care at a university hospital]. / Psychosoziale Unterstützung während der COVID-19-Pandemie: interdisziplinäres Versorgungskonzept an einem Universitätsklinikum.

BACKGROUND: Since the beginning of the outbreak, the COVID-19 pandemic has caused an increased demand for psychosocial support for patients, their family members, and healthcare workers. Concurrently, possibilities to provide this support have been hindered. Quarantine, social isolation, and SARS-CoV­2 infections represent new and severe stressors that have to be addressed with innovative psychosocial care. OBJECTIVE AND METHOD: This article describes the COVID-19 psychosocial first aid concept at the University Hospital Munich (LMU Klinikum) developed by an interdisciplinary team of psychiatric, psychological, spiritual care, psycho-oncological, and palliative care specialists. RESULTS: A new psychosocial first aid model has been implemented for COVID-19 inpatients, family members, and hospital staff consisting of five elements. CONCLUSION: The concept integrates innovative and sustainable ideas, e.g. telemedicine-based approaches and highlights the importance of multidisciplinary collaboration to cope with challenges in the healthcare system.

Cannabis use and psychosis: a review of reviews.

We conducted a systematic review of meta-analyses and systematic reviews to evaluate the impact of cannabis use on the onset and course of psychoses. Following a systematic literature search of five data bases (2005-2016) and consecutive structured evaluation, we were able to include 26 systematic reviews and meta-analyses. The methodological quality of the included publications were in the range of high and poor. The scientific literature indicates that psychotic illness arises more frequently in cannabis users compared to non-users, cannabis use is associated with a dose-dependent risk of developing psychotic illness, and cannabis users have an earlier onset of psychotic illness compared to non-users. Cannabis use was also associated with increased relapse rates, more hospitalizations and pronounced positive symptoms in psychotic patients. We make recommendations about the type of research that is required to better characterize the relationship between cannabis use and the development and outcomes of psychosis.

How effective and safe is medical cannabis as a treatment of mental disorders? A systematic review.

We conducted a review of systematic reviews (SRs) and randomized-controlled trials (RCTs) to analyze efficacy and safety of cannabis-based medication in patients with mental disorders. Five data bases were systematically searched (2006-August 2018); 4 SRs (of 11 RCTs) and 14 RCTs (1629 participants) were included. Diagnoses were: dementia, cannabis and opioid dependence, psychoses/schizophrenia, general social anxiety, posttraumatic stress disorder, anorexia nervosa, attention-deficit hyperactivity disorder, and Tourette`s disorder. Outcome variables were too heterogeneous to conduct a  meta-analysis. A narrative synthesis method was applied. The study quality was assessed using the risk-of-bias tool and SIGN-checklists. THC- and CBD-based medicines, given as adjunct to pharmaco- and psychotherapy, were associated with improvements of several symptoms of mental disorders, but not with remission. Side effects occurred, but severe adverse effects were mentioned in single cases only. In order to provide reliable treatment recommendations, more and larger RCTs with follow-up assessments, consistent outcome measures and active comparisons are needed.

Advanced formulation of methacryl- and acetyl-modified biomolecules to achieve independent control of swelling and stiffness in printable hydrogels.

Biobased hydrogels are considered to mimic native extracellular matrix due to their high water content and are considered as adequate matrices for cell encapsulation. However, the equilibrium degree of swelling (EDS) and stiffness of simple hydrogel formulations are typically confined: Increasing polymer concentration results in increasing stiffness and simultaneously decreasing EDS. The aim of this contribution was to decouple this standard correlation between polymer content, stiffness and EDS as well as the assembly of hydrogels with graded composition of hydrogels by layer-wise printing. We investigated two sets of formulations, which consisted of three different compositions with increasing total biopolymer concentration (10.6%, 11.5%, 13.0%). Within these compositions the amount of gelatin methacryloyl acetyl (GMA) was constant (10%), whereas the proportion of methacrylated hyaluronic acid and chondroitin sulfate increased. In the first set of formulations GMA with one fixed degree of methacryloylation (DM) was used, whereby the storage modulus (G') increased from ~10 to ~25 kPa and the EDS decreased from ~700 to ~600%. In the second set of formulations we gradually lowered the DM of the GMA in parallel to increase of polymer concentration and achieved an increase of both, G' from ~11 to ~18 kPa and EDS from ~690 to ~790%. By dispensing these compositions, we created a glycosaminoglycan-graded hydrogel. We proved the cytocompatibility of the dispensing process, the used photoinitiator lithium phenyl-2,4,6-trimethylbenzoylphosphinate, and layer-wise UVA irradiation. Glycosaminoglycan gradient was proved stable for 28 d,encapsulated chondrocytes were viable and produced new matrix.

[Medicinal cannabis and cannabis-based medication: an appeal to physicians, journalists, health insurances, and politicians for their responsible handling]. / Medizinalcannabis und cannabisbasierte Arzneimittel: ein Appell an Ärzte, Journalisten, Krankenkassen und Politiker für einen verantwortungsvollen Umgang.

Since the adoption of the law of March 6, 2017, any German physician can prescribe medical cannabis flowers and cannabis-based magistral and finished medicinal products. No specific indications for prescriptions are provided in the law. The statutory health insurance companies bear the costs once an application for cost coverage has been approved by the Medical Service of the Health Funds. The German associations of psychiatry (child, adolescents, and adults), neurology, palliative care, addictology, and pain medicine are watching these developments in the media, politics, and medical world with concern due to: the option to prescribe cannabis flowers despite the lack of sound evidence and against the recommendations of the German Medical Association; the lack of distinction between medical cannabis flowers and cannabis-based magistral and finished medical products; the indiscriminately positive reports on the efficacy of cannabis-based medicines for chronic pain and mental disorders; the attempts by the cannabis industry to influence physicians; the increase in potential indications by leaders of medical opinion paid by manufacturers of cannabis-based medicines. The medical associations make the following appeal to journalists: To report on the medical benefits and risks of cannabis-based medicines in a balanced manner. To physicians: to prescribe cannabis-based medicines with caution; to prefer magistral and finished medicinal products over cannabis flowers. To politicians: to consider data according to the standards of evidence-based medicine when making decisions and provide financial support for medical research into cannabis-based medicines.

[Cannabis, Cannabinoids and Cannabis Use Disorders]. / Cannabis, Cannabinoide und Cannabiskonsumstörungen.

Cannabis currently leads to intensive, and sometimes highly emotional discussions like no other drug. What are the health and social risks, if the substance is used recreationally? This article describes the most important cannabinoids, the endogenous cannabinoid system and possible risks of cannabis if used as drug. Psychotherapeutic treatment options of cannabis abuse and dependence are shown.

[Efficacy and safety of medicinal cannabis: results of the CaPRis study]. / Wirksamkeit und Sicherheit von Cannabisarzneimitteln: Ergebnisse der CaPRis-Studie.

In the 1990s, the endocannabinoid system was discovered as part of the human physiology. Since then, the effects of cannabis as a medicine have been researched more systematically. To summarize the scientific knowledge, the German Federal Ministry of Health commissioned an expertise.The project "Cannabis: Potential and Risks: a Scientific Analysis" (CaPRis), which started in 2016, aimed at analyzing the potential of medicinal cannabis and the risks of recreational cannabis use. A search of systematic reviews (SRs) and randomized-controlled trials (RCTs) were conducted in five international databases (publication date: 2006-2017). For the medical use of cannabis 16 SRs (of 186 RCTs) were included from a global search and nine further RCTs were comprised from a de novo search. All studies were methodologically assessed.Evidence for the efficacy of cannabis medicine (given as an adjunct to other medication) was found in patients with chronic pain and spasticity due to multiple sclerosis. Benefits were also found for appetite stimulation, improvement of nausea, and weight gain in patients with cancer, HIV/AIDS or in palliative care. Effects were often small. For other physical or mental disorders, only few or no controlled human studies are available. Adverse effects of cannabis medicine are often reported; severe adverse effects were mentioned in single cases only.To provide reliable treatment recommendations for clinicians and patients, more large-sized RCTs with follow-up assessments, consistent outcome measures, and active comparisons are needed.

Is Cannabis Use Treatment Also Indicated for Patients with Low to Moderate Polysubstance Use.

BACKGROUND: Polysubstance use (PSU) is common among patients with cannabis use (CU) and is related to more severe CU problems. However, it is unclear how PSU predicts CU treatment outcomes beyond CU patterns. We examined the frequency, amount, and class of additionally used substances as predictors for primary and secondary outcomes. METHODS: We conducted crude and adjusted regression analyses for PSU variables as predictors of remission, abstinence, -reduction, and secondary outcomes in 166 help-seeking -patients from a randomized clinical trial of CANDIS, a -cognitive behavioral treatment program. RESULTS: Patients with recent illegal PSU experienced more difficulties in reducing their CU (B = -1.22, p < 0.001). In contrast, remission rates were slightly higher in patients with a wide variety of -last-year-PSU (RD = 0.04, p < 0.001). Amphetamine use -predicted poorer outcomes regarding CU-related problems (B = -4.22, p = 0.019), and the use of opiates, inhalants, and dissociative substances predicted poorer physical health outcomes (B = -0.62, p = 0.009; B = -0.96, p = 0.039; B = -1.18, p = 0.007). CONCLUSIONS: CU treatment is also effective for patients with moderate PSU. However, treatment effects may be enhanced by addressing specific PSU characteristics as part of a modularized program.

[Health Care Organization - The New German S3-Guideline on Alcohol-Related Disorders and its Relevance for Health Care]. / Versorgungsorganisation ­ Die neue S3-Leitlinie Alkohol und ihre Bedeutung für die Versorgungspraxis.

BACKGROUND: Alcohol dependence is one of the most serious diseases of addiction in Germany. The new S3-guideline "Screening, Diagnostics and Treatment of Alcohol-Related Disorders" has been presented in 2015 and summarizes the present state of knowledge pertaining to the diagnosis and treatment of alcohol abuse and alcohol dependence. METHODS: This guideline was developed over four years within the framework of the Association of the Scientific Medical Societies in Germany (AWMF). The German Association for Psychiatry, Psychotherapy and Psychosomatics (DGPPN) and the German Society for Research and Therapy in Addiction (DG-Sucht) took the lead in the organization. More than 50 professional societies and associations and health organizations as well as more than 60 acknowledged experts were involved, including networks of self-help groups and relatives. The working group on "health care organization", whose results are presented here, was one out of thirteen working groups, focusing on the task how to implement the guideline under the basic conditions of the German health care system with its sectors and interfaces. RESULTS: For the chapter on "health care organization" 27 recommendations have been consented. Many of these have been prepared by the respective working groups. These recommendations cover areas such as screening, diagnostics and short interventions, detoxification and withdrawal as well as pharmacotherapy, physical complications and psychic comorbidity, medical rehabilitation and other forms of post-acute treatment, primary care by general practitioners, as well as specific target groups such as children and adolescents, (pregnant) women and the elderly, and, in addition, self-help approaches. CONCLUSION: For needs-based diagnostics and treatment of alcohol-related disorders, guideline-based recommendations for health care organization offer a framework for the cooperation and coordination of all health sectors and occupational groups, especially with respect to their interfaces. This includes the cooperation between the medical and the psychosocial system and stretches from harm reduction to social inclusion of people concerned. Particularly the field of rehabilitation with its explicit aims for participation relies heavily on such a cooperation.

German Guidelines on Screening, Diagnosis and Treatment of Alcohol Use Disorders.

Evidence-based strategies for screening, diagnosing and treating alcohol use disorders (AUD) are instrumental in the early and better management of individuals at risk for or suffering from AUD. However, existing guidelines vary and may be biased by conflicts of interests. Unbiased recommendations can be achieved only if sufficient detail is provided on the composition and representativeness of author groups, methodological rigor, handling of potential conflicts of interest and financing. This paper presents the first evidence-based guidelines for AUD from German-speaking countries. These guidelines are based on the work of delegates from a representative sample of 46 scientific societies (mostly medical) from Austria, Germany and Switzerland dealing with AUD. It also included patients and relatives. Recommendations were derived from a standardised hierarchical process involving quality controls drawn from existing guidelines, de novo literature searches and/or expert experience. Potential conflicts of interest were assessed yearly and led to exclusion from voting in specific areas. An overall cost of more than 400,000€ (for alcohol and tobacco guidelines) were exclusively covered by the participating societies and academic institutions. More than 100 recommendations on screening, diagnostics and treatment of AUD are outlined in this paper, and their scientific background is given in the online supplementary material. Tables of aggregated study synopses (in English) and the full version of guidelines (in German) are available (see "Links").

A Brief Outline of the Use of New Technologies for Treating Substance Use Disorders in the European Union.

BACKGROUND: Clinicians in the field of drug addiction have started to exploit the growth of Technology-Based Interventions (TBIs). However, there is little information on how health personnel evaluate them. METHODS: Semi-structured interviews were conducted among 20 European experts. RESULTS: All of the interviewees recognised TBIs as a valuable tool to improve the management of substance-use disorders (SUDs). Most interviewees indicated that combining both traditional face-to-face therapist-patient clinic appointment with TBIs is probably the most effective method. Most interviewees agree that TBIs are valuable tools to overcome both physical and social barriers, and hence significantly facilitate the access to treatment. Poor infrastructure and lack of digital literacy are recognised as major barriers to the diffusion of these tools. CONCLUSIONS: The application of various forms of technology in SUD treatment is an interesting development for the European Union. Technical and non-technical barriers exist and impede their full exploitation.
