Unintentional Pediatric Cannabis Exposures After Legalization of Recreational Cannabis in Canada

Abstract: This cross-sectional study examines changes in emergency department visits and hospitalizations due to cannabis exposures among children after legalization of recreational cannabis in Canada.

Interrupted time series analysis of Canadian legal cannabis sales during the COVID‐19 pandemic

Abstract: Abstract Introduction There were repeated reports of increased cannabis sales, use and health impacts in Canada during the COVID‐19 pandemic. However, it was unclear whether the increases were due to pandemic effects or industry expansion. Methods We performed interrupted time series regressions of monthly per capita legal cannabis sales from March 2019 to February 2021, first with national averages, then with provincial/territorial data after adjusting for store density. We considered two interruption alternatives: January 2020, when product variety increased; and March 2020, when pandemic restrictions began. Results The provincial/territorial regression with the January interruption explained R 2 = 69.6% of within‐jurisdiction variation: baseline monthly per capita sales growth averaged $0.21 (95% confidence interval [CI] 0.15, 0.26), sales immediately dropped in January by $1.02 (95% CI −1.67, −0.37), and monthly growth thereafter increased by $0.16 (95% CI 0.06, 0.25). With the March interruption, the regression instead explained 68.7% of variation: baseline sales growth averaged $0.14 (95% CI 0.06, 0.22), there was no immediate drop and growth thereafter increased by $0.22 per month (95% CI 0.08, 0.35). Discussion and Conclusions Increasing cannabis sales during the pandemic was consistent with pre‐existing trends and increasing store numbers. The extra increased growth was more aligned with January's new product arrivals than with March's pandemic measures, though the latter cannot be ruled out. We found little evidence of pandemic impacts on Canada's aggregate legal cannabis sales. We therefore caution against attributing increased population‐level cannabis use or health impacts primarily to the pandemic.

Reducing the harm of "harm reduction".

Abstract: The article in this issue by Alan Leshner tackles one of the most contentious issues in drug use policy today and argues that we should dispense with "harm reduction" altogether--not the programs, policies, and interventions to which this term refers but the term itself. He makes the case that the initial clarity and simplicity of the phrase "harm reduction" have evolved into an emotion-laden designation that is interfering with the implementation and evaluation of public health programs.

Hours and Days of Sale and Density of Alcohol Outlets: Impacts on Alcohol Consumption and Damage: A Systematic Review

Abstract: Aims: The aim of this study was to examine recent research studies published from 2000 to 2008 focusing on availability of alcohol: hours and days of sale and density of alcohol outlets. Methods: Systematic review. Results: Forty-four studies on density of alcohol outlets and 15 studies on hours and days of sale were identified through a systematic literature search. The majority of studies reviewed found that alcohol outlet density and hours and days of sale had an impact on one or more of the three main outcome variables, such as overall alcohol consumption, drinking patterns and damage from alcohol. Conclusions: Restricting availability of alcohol is an effective measure to prevent alcohol-attributable harm.

Interventions to reduce HIV transmission related to injecting drug use in prison Elements of a comprehensive programme to prevent HIV transmission in prisons

Abstract: The high prevalence of HIV infection and drug dependence among prisoners, combined with the sharing of injecting drug equipment, make prisons a high-risk environment for the transmission of HIV. Ultimately, this contributes to HIV epidemics in the communities to which prisoners return on their release. We reviewed the effectiveness of interventions to reduce injecting drug use risk behaviours and, consequently, HIV transmission in prisons. Many studies reported high levels of injecting drug use in prisons, and HIV transmission has been documented. There is increasing evidence of what prison systems can do to prevent HIV transmission related to injecting drug use. In particular, needle and syringe programmes and opioid substitution therapies have proven effective at reducing HIV risk behaviours in a wide range of prison environments, without resulting in negative consequences for the health of prison staff or prisoners. The introduction of these programmes in countries with an existing or emergent epidemic of HIV infection among injecting drug users is therefore warranted, as part of comprehensive programmes to address HIV in prisons.

Prevalence of Adult Problem and Pathological Gambling between 2000 and 2005: An Update

Abstract: Excessive gambling is a prominent Public Health problem with high prevalence rates in many countries. Substance abuse and other co-morbidities often constitute a major health hazard for the person which gambles with a loss of material and social resources, as well as being a major concern for his or her significant others. The present study updates and extends prevalence data to include work published between 2000 and 2005 in English and other European languages. In a three-step search and exclusion process, studies with current adult prevalence rates were gathered. Almost all studies fulfil basic research standards. The weighted mean prevalence rates for excessive gambling (problem and pathological) are 3.0% for the South Oaks Gambling Survey (problem 1.2%; pathological 1.8%), 3.3% for the Canadian Problem Gambling Index (problem 2.4%; pathological 0.8%) and 3.1% for the DSM-IV (problem 1.9%; pathological 1.2%). The prevalence rates are comparable and relatively stable between countries and across survey instruments, and do not differ from earlier reviews. The regular epidemiological monitoring of excessive gambling remains a major Public Health issue although the distinction between pathological and problem gambling is not appropriate for epidemiological research. Further studies are needed with respect to concomitant lifestyle characteristics.
