Aim
To quantify the trends in frequent and occasional cannabis vaping, demographic differences and concurrent nicotine and alcohol use.
Design
Observational study. Survey‐weighted multinomial logistic regression models assessed trends and disparities in past 30‐day cannabis use. Trends were assessed overall and by sex, race/ethnicity, parental education and urbanicity. Multinomial logistic regression...
Background and aims
There are few longitudinal studies assessing the association of cannabis use and subsequent onset of bipolar disorder. We aimed to measure the association between early cannabis exposure and subsequent bipolar disorder.
Design, Setting and Participants
Observational study linking a sample from the northern Finland birth cohort 1986 (n = 6325) to nation‐wide register data to...
Background and Aims
The time lag encountered when accessing health‐care data is one major barrier to implementing opioid overdose prediction measures in practice. Little is known regarding how one's opioid overdose risk changes over time. We aimed to identify longitudinal patterns of individual predicted overdose risks among Medicaid beneficiaries after initiation of opioid prescriptions.

Background and aims
Previous analyses of the effect of e‐cigarettes on real world smoking cessation success have mainly been based on surveys undertaken in the United States and United Kingdom, where nicotine e‐cigarettes can be readily obtained. In Australia, regulations have made obtaining e‐cigarettes containing nicotine difficult. The effectiveness of e‐cigarette use as a smoking cessation aid...
Background and aims
Alcohol use increases throughout adolescence. Emergency department (ED) attendance is an opportunity for alcohol screening and brief intervention (ASBI), which is effective for adults. This trial evaluated the effectiveness and cost‐effectiveness of ASBI compared with screening alone (SA) in high‐risk adolescents.
Design, Setting and Participants
Multi‐centre, three‐group, single‐blind,...
Aims
To estimate longitudinal pathways from childhood socio‐economic position (SEP) to educational attainment and mid‐life heavy drinking in black Americans in order to identify potential points of early intervention to reduce risk for alcohol‐related problems in adulthood.
Design, Setting and Participants
Data are from 1299 black Americans in the US National Longitudinal Survey of Youth, followed...
Background and Aims
In previous research, the spatial distribution of alcohol outlets has been shown to be related to the spatial distribution of crime. However, the spatial distribution of alcohol outlets is also related to the spatial distribution of other retail (and non‐retail) activities. We measured whether a residual relationship between alcohol outlets and crime remains statistically significant...
Aim
To (i) estimate the prevalence of adolescent vaping in 47 lower‐middle, upper‐middle and high‐income countries, and (ii) test the association between implementation of World Health Organisation (WHO) tobacco control policies and adolescent e‐cigarette use (also known as vaping) in 44 countries where implementation data were available.
Design
Cross‐sectional surveys.
Settings
A total of 47...
Background and Aims
Hong Kong reduced beer and wine tax in 2007, eliminated taxes on beer and wine and strengthened drink‐driving legislation in 2008, and increased police traffic enforcement after the 2014 social unrest. This study aimed to measure the effects of implementing road safety policies on road traffic harm in the context of deregulated alcohol control policy in Hong Kong.
Design
Population‐based...
