Dropout rates of in‐person psychosocial substance use disorder treatments: a systematic review and meta‐analysis
About 30% of participants drop out of in‐person psychosocial substance use disorder treatment studies. Rates vary with the treated population, the substance being targeted, and the characteristics of the treatment.
The decline in youth drinking in England—is everyone drinking less? A quantile regression analysis
Alcohol consumption among young people in England appears to be declining across the consumption distribution, and peaks among heavy drinkers.
Contextual characteristics of adults’ drinking occasions and their association with levels of alcohol consumption and acute alcohol‐related harm: a mapping review
Studies from 1975 to 2019 using event‐level methods to estimate associations between contextual characteristics of drinking occasions, consumption levels and acute harms focused mainly on students and consumption outcomes, and most considered a limited range of contextual characteristics.
Comparison of psychiatric comorbidity in treatment‐seeking, opioid‐dependent patients with versus without chronic pain
People in opioid treatment services in Scotland who report chronic pain may have a higher prevalence of psychiatric comorbidity than those who do not.
Opioid use and dropout from extended‐release naltrexone in a controlled trial: implications for mechanism
Extended‐release injection naltrexone was effective at reducing the risk of dropout from opioid use disorder treatment after an episode of opioid use.
The Psychoactive Surveillance Consortium and Analysis Network (PSCAN): the first year
During its first year (2016-17), PSCAN captured clinical data on new classes of drugs paired with biological samples. Synthetic cannabinoids were the most common new psychoactive drug. Synthetic opioids were associated with a high rate of intubation and respiratory acidosis.
Recent trends in heroin and pharmaceutical opioid‐related harms in Victoria, Australia up to 2018
In Victoria, Australia, there appears to have been a trend starting mid‐2014 of increasing heroin‐related harm and a flattening of the increase or a decrease of harms relating to pharmaceutical opioids.
Life‐course trajectories of cannabis use: a latent class analysis of a New Zealand birth cohort
In New Zealand, long‐term frequent cannabis use, or transition to such use, appears to be associated with diverse harms in adulthood.
Maternal and infant characteristics associated with maternal opioid overdose in the year following delivery
Risk factors associated with postpartum opioid overdose include a history of overdose during pregnancy, a diagnosis of opioid use disorder, neonatal opioid withdrawal, and greater than average use of emergency care in year before the birth.
Population‐level predictors of changes in success rates of smoking quit attempts in England: a time series analysis
In England between 2007 and 2018, licensing of nicotine replacement therapy for use in harm reduction, greater use of e‐cigarettes and prescription medications during a quit attempt and higher expenditure on tobacco control mass media were all associated with higher success rates of quit attempts.
Assessment of the Choice Behavior Under Cued Conditions (CBUCC) paradigm as a measure of motivation to smoke under laboratory conditions
In the Choice Behavior under Cued Conditions (CBUCC) task, which assesses motivation to smoke under laboratory conditions, smoking abstinence appears to generate greater cue-specific spending.
Association of parental substance use disorder with offspring cognition: a population family‐based study
There appear to be shared genetic factors between parental substance use disorder (SUD) and offspring cognitive function, suggesting that cognitive deficits may constitute a genetically transmitted risk factor in SUD.
Sibling comparisons elucidate the associations between educational attainment polygenic scores and alcohol, nicotine and cannabis
Individuals who carry more alleles associated with educational attainment tend to meet fewer clinical criteria for alcohol, nicotine and cannabis use disorders.
Increases in methamphetamine use among heroin treatment admissions in the United States, 2008–17
Methamphetamine use among heroin treatment admissions in the United States increased from one in 50 primary heroin treatment admissions in 2008 to one in 8 admissions in 2017.
Factor structure, internal reliability and construct validity of the methadone maintenance treatment stigma mechanisms scale (MMT‐SMS)
The Methadone Maintenance Treatment Stigma Mechanisms Scale appears to be a reliable measure of methadone maintenance treatment stigma with robust validity.
Measuring fidelity to behavioural support delivery for smoking cessation and its association with outcomes
The fidelity index is a reliable measure for quantifying intervention fidelity of delivering smoking cessation behavioural support.
