Newest firstBackground: The illegal status of recreational cannabis (RC) is often considered a barrier to its use. RC was partially legalized in Germany in 2024. This study investigated whether attitudes towards cannabis were different in patients surveyed after recreational cannabis legalization (RCL), compared with patients surveyed before RCL. Method: In 2022 (pre-RCL) and 2024/2025 (post-RCL), patients without psychosis a…
Open article record in new tab ↗HintergrundBis vor 25 Jahren waren zyklische Brechattacken unter chronischem Cannabiseinfluss nahezu unbekannt. Nach der Legalisierung nichtmedizinischen Cannabis in Nordamerika und der damit einhergehenden Zunahme des Cannabiskonsums, einschließlich hochpotenter Sorten steigt dort die Zahl der Patienten mit cannabisbezogenem zyklischem Erbrechen. Die ROME-IV-Kriterien der Rome Foundation definieren das cannabisin…
Open article record in new tab ↗Background The lockdown measures during the SARS-CoV-2 pandemic could have influenced drug consumption patterns of persons with drug use disorder, especially due to a reduced availability of drugs, an increased consumption of sedating substances as a coping strategy, or a shift to novel psychotropic substances (NPS) associated with an increased drug buying in the internet. In this study, the consumption patterns o…
The interaction between cannabis use or addiction and SARS-COV-2 infection rates and COVID-19 outcomes is obscure. As of 08/01/2022 among 57 evaluated epidemiological/clinical studies found in Pubmed-database, most evidence for how cannabis use patterns were influenced by the pandemic was given by two systematic reviews and 17 prospective studies, mostly involving adolescents. In this age group, cannabis use patte…
Open article record in new tab ↗Background The prevalence of cannabis use and cannabis use disorders (CUD) has significantly increased over time. However, there are no approved pharmacological treatments for CUD. The aim of this study was to determine the efficacy and safety of various medical cannabinoids in the treatment of CUD. Methods We conducted a systematic review of randomized controlled trials which evaluated the therapeutic potential o…
Open article record in new tab ↗Background There is a lack of benefit/harm assessments of illicit and licit psychoactive substances performed by substance-dependent users in comparison to addiction medicine experts. Methods We extended the analyses of substance harm/benefit assessments of German addiction medicine experts (N = 101), in parts reported recently in this journal [doi.org/10.3389/fpsyt.2020.59219], by the perspectives of substance-ad…
Open article record in new tab ↗The Research Domain Criteria (RDoC) approach seeks to understand mental functioning in continuous valid dimensions ranging from functional to pathological. Reward processing is a transdiagnostic functioning domain of the RDoC. Due to prototypical abnormalities, addictions are especially applicable for the investigation of reward processing. Subjective reward processing is challenging to determine and differs betwe…
Open article record in new tab ↗Background: In response to the COVID-19-pandemic, a lockdown was established in the middle of March 2020 by the German Federal Government resulting in drastic reduction of private and professional traveling in and out of Germany with a reduction of social contacts in public areas. Research Questions: We seek evidence on whether the lockdown has led to a reduced availability of illegal drugs and whether subjects wi…
Background Only a minority of subjects with substance use disorders (SUDs) are in addiction-specific treatment (treatment gap). Co-operation between an unemployment office and a psychiatric hospital was established for the assessment and counseling of long-term unemployed clients with SUD. We aim at validating whether such a treatment gap exists in that group, and whether clients from an unemployment office differ…
BACKGROUND: About 15 years ago, a diverse group of new recreational psychotropic substances began to emerge, which were marketed for example as "legal highs," "research chemicals," or "designer drugs." These substances were later subsumed under the label "Novel Psychoactive Substances" (NPS). Important NPS classes are cathinones, synthetic cannabimimetics, phenethylamines, and herbal drugs. The health care system…
Background: For cannabis-dependent subjects, the relationship between cannabis withdrawal syndrome (CWS) severity and the urine cannabinoid concentrations are unclear; we investigated this using a commercial point-of-care (POC) enzyme immunoassay detecting 11-nor-9-carboxy-Delta-9-tetrahydrocannabinol (THC-COOH). Methods: Observational study of 78 adult chronic cannabis-dependent subjects assessed over a 24-day in…
Background: Over the past 15 years, comparative assessments of psychoactive substance harms to both users and others have been compiled by addiction experts. None of these rankings however have included synthetic cannabinoids or non-opioid prescription analgesics (NOAs, e.g., gabapentinoids) despite evidence of increasing recreational use. We present here an updated assessment by German addiction medicine experts,…
