Background:

Previous research using whole-brain neuroimaging techniques has revealed structural differences of grey matter (GM) in alcohol use disorder (AUD) patients. However, some of the findings diverge from other neuroimaging studies and require further replication.

Publication Date

Abstract

Background

Alcohol-attributable costs to society are captured by cost-of-illness studies, however estimates are often not comparable, e.g. due to the omission of relevant cost components. In this contribution we (1) summarize the societal costs attributable to alcohol use, and (2) estimate the total costs under the assumption that all cost components are considered.

Abstract

Importance: Cannabis withdrawal syndrome (CWS)—a diagnostic indicator of cannabis use disorder—commonly occurs on cessation of heavy and prolonged cannabis use. To date, the prevalence of CWS syndrome has not been well described, nor have the factors potentially associated with CWS.

Summary

Background

Approximately 188 million people use cannabis yearly worldwide, and it has recently been legalised in 11 US states, Canada, and Uruguay for recreational use. The potential for increased cannabis use highlights the need to better understand its risks, including the acute induction of psychotic and other psychiatric symptoms.

Abstract

Importance: The number of children with prenatal opioid exposure to medication for addiction treatment (MAT) with methadone and buprenorphine for maternal opioid use disorder is increasing, but the associations of this exposure with cognitive outcomes are not well understood.

Researchers have continuously debated the link between anxiety and alcohol use. However, despite the previous examination of the direction and strength of the association, the form of the relationship remains unclear.

Cannabis Use during Methadone Maintenance Treatment for Opioid Use Disorder: A Systematic Review and Meta-Analysis

Publication Date

Abstract

Background: Rates of cannabis use among patients receiving methadone maintenance therapy are high, and cannabis use may be associated with outcomes of methadone maintenance therapy. We examined the effect of cannabis use on opioid use in patients receiving methadone maintenance therapy to test the hypothesis that cannabis use is associated with a reduction in opioid use.

Findings of this comprehensive review seem to almost entirely deflate what in the mid-2000s was a bubble of enthusiasm for parental programmes as a way to prevent or reduce drinking among teenagers - but despite this overall verdict, some interventions have had remarkable results.
