Background and Aims
The most available data on the prevalence of cannabis use come from population surveys conducted in high‐income countries in North America, Oceania and Europe. Less is known about the prevalence of cannabis use in Africa. This systematic review aimed to summarize general population‐level cannabis use in sub‐Saharan Africa since 2010.
Methods
A comprehensive search was conducted...
An increased use of high‐potency cannabis products since cannabis legalization in the United States, Canada and elsewhere may increase cannabis‐related harm. Policymakers have good reasons for regulating more potent cannabis in ways that minimize harm, using approaches similar to those used to regulate alcohol; namely, banning the sale of high‐potency cannabis, setting a cap on tetrahydrocannabinol...
Background and aim
The prevalence of tobacco smoking has declined in most high‐income countries, while cannabis use has been rising. Moreover, cannabis use has been found to have increased among cigarette smokers in recent years in jurisdictions where it has been either decriminalized or legalized. This study measured trends in cannabis, tobacco and the co‐use of cannabis and tobacco in Australia...
Randomized controlled trials (RCTs) are the gold standard for making causal inferences, but RCTs are often not feasible in addiction research for ethical and logistic reasons. Observational data from real‐world settings have been increasingly used to guide clinical decisions and public health policies. This paper introduces the potential outcomes framework for causal inference and summarizes well‐established...
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...
Aim
To test (1) if there was a change in self‐reported lifetime prevalence of meth/amphetamine use by birth cohort and (2) if the extent of under‐reporting of meth/amphetamine use was associated with the proportion of the population who nominated meth/amphetamine as a drug problem.
Design
Observational study using seven waves of repeated cross‐sectional nationally representative household surveys...
Aims
To estimate the treatment rate for alcohol use disorders (AUDs) in the general adult population. Treatment rates were also considered in relation to economic differences.
Methods
Systematic review and meta‐analysis. We searched PubMed, EMBASE, PsycINFO and CINAHL databases to identify studies that reported treatment rates for alcohol use disorders in the general population. Independent reviewers...
Background and Aims
There has been an increase in the potency of cannabis during the last two decades and adoption of a novel method of administration—vaping. YouTube, a social media platform, has become a popular source to access cannabis‐related information. This study aimed to identify cannabis vaping YouTube videos from 2016 to 2020 and examine the themes and metrics.
Design
Cross‐sectional...
Background and Aims
Studies have consistently found a longitudinal association between e‐cigarette use (vaping) and cigarette smoking. Many have interpreted such association as causal. This systematic review and meta‐analysis evaluated the plausibility of a causal interpretation by (1) estimating the effect of adolescent vaping on smoking initiation, adjusted for study quality characteristics, (2)...
Aims
To (1) identify population‐level classes of polysubstance use among young Australians between 2004 and 2016, (2) test if these classes changed over the same period, in terms of class prevalence and probabilities of substance use within each class, and (3) identify demographic and health‐related correlates of polysubstance use.
Design
Repeated cross‐sectional nationally representative household...
Aim
To assess (1) how far smoking patterns, depression and smoking‐related beliefs and intentions predict vaping uptake, current vaping and vaping frequency among daily smokers; and (2) how far the aforementioned predictors and baseline vaping frequency predict current vaping among those who reported ever vaped.
Design
Analysis of data from six waves of a longitudinal survey over 8 years. Longitudinal...
Background and Aims
People who have recently injected drugs are a priority population in efforts to achieve hepatitis C virus (HCV) elimination. This study estimated the prevalence and number of people with recent injecting drug use living with HCV, and the proportion of people with recent injecting drug use among all people living with HCV infection at global, regional and country‐levels.
Methods...
Aims
This review provides an up‐to‐date curated source of information on alcohol, tobacco and illicit drug use and their associated mortality and burden of disease. Limitations in the data are also discussed, including how these can be addressed in the future.
Methods
Online data sources were identified through expert review. Data were obtained mainly from the World Health Organization, United...
Aim
To test if the degree of change in cannabis use between 2001 and 2013 differed according to socio‐economic status.
Design
Repeated cross‐sectional household surveys that were nationally representative.
Setting
Australia.
Participants
Adult samples from the 2001 and 2013 National Drug Strategy Household Surveys (n = 23 642 in 2001 and n = 21 353 in 2013), the largest nationally representative...
