Craving mediates the association between momentary pain and illicit opioid use during treatment for opioid‐use disorder: an ecological momentary assessment study

Among people receiving opioid agonist treatment, momentary pain appears to be indirectly associated with illicit opioid use via momentary opioid craving.

Dependence on nicotine in US high school students in the context of changing patterns of tobacco product use

Among US high school students, increases in the prevalence of nicotine product use from 2012 to 2019 do not appear to have been accompanied by a similar increase in the population burden of nicotine dependence.

Education tracking and adolescent smoking: a counterfactual and prospective cohort study

Education tracking (placing students into different curricula based on learning needs or abilities) appears to be a risk factor for adolescent smoking among Taiwanese adolescents.

Emergence of wasp dope in rural Appalachian Kentucky

Among people who use drugs in rural Kentucky, USA, more than one in six people surveyed reported using wasp dope (made from insecticides) in the past 6 months, nearing the percentage using cocaine/crack (20%) and fentanyl/carfentanil (25%).

Factors associated with severity, incidence or persistence of internet gaming disorder in children and adolescents: a 2‐year longitudinal study

Among adolescents in South Korea, ADHD symptoms and more than 4 hours per day of on‐line games were associated with the occurrence or persistence of high risk for internet gaming disorder.

First‐time offenders for recreational ketamine use under a new penalty system in Taiwan: incidence, recidivism and mortality in national cohorts from 2009 to 2017

Prevalence and patterns of hospital use for people with frequent alcohol‐related hospital admissions, compared to non‐alcohol and non‐frequent admissions: a cohort study using routine administrative hospital data

People with repeated admissions for alcohol‐related problems in England appear to be a high‐cost, high‐need, complex group of patients that makes up more than a quarter of the country's alcohol admissions.

Alcoholic beverage odor, a proximal cue for alcohol consumption, appears to reinforce conditioning of neurophysiological responses to a novel cue among low alcohol sensitivity (LS) individuals.

Restricting the availability of alcohol from on‐premises during the first and second waves of the COVID‐19 pandemic in Australia was associated with significant reductions in on‐premises beer consumption, but not significant changes in off‐premises beer consumption.
