Cannabis-related arrests and convictions in Canada: Differences by race/ethnicity, individual socioeconomic factors, and neighborhood deprivation.

Racialized individuals were disproportionately impacted by cannabis prohibition in Canada; however, the role of socioeconomic factors and neighborhood deprivation are not well understood. The current study examined race/ethnicity, individual socioeconomic factors, and neighborhood deprivation in relation to arrests and convictions for cannabis-related offenses. Repeat cross-sectional data were analyzed from two waves of the International Cannabis Policy Study (ICPS), a web-based survey conducted in 2019 (n = 12,226) and 2020 (n = 12,815) in Canada among those aged 16 to 65. Respondents were recruited through commercial online panels. Respondents' postal codes were linked to the INSPQ deprivation index. Multinomial regression models examined the association between race/ethnicity, individual socioeconomic factors, neighborhood deprivation, and lifetime arrests or convictions for cannabis offenses. Overall, 4.4% of respondents reported a lifetime arrest or conviction for a cannabis-related offense. Black and Indigenous individuals had more than three times the odds of conviction than White individuals (AOR = 3.90, 95% CI = 2.07-7.35, p = <0.01; AOR = 3.24, 95% CI = 1.78-5.90, p = <0.01, respectively). Differences were still statistically significant after adjusting for cannabis use and socioeconomic factors; however, after adjusting for neighborhood deprivation, only the difference for Black individuals remained. Neighborhood deprivation was associated with cannabis-related convictions: the odds of a conviction among the "most privileged" and "privileged" neighborhoods were approximately half of those in the "most deprived" neighborhoods (AOR = 0.50, 95% CI = 0.29-0.86, p = 0.01; AOR = 0.50, 95% CI = 0.27-0.92, p = 0.03, respectively). Arrests and convictions for cannabis-related offenses were disproportionately higher among racialized individuals and those living in the most marginalized neighborhoods. Future research should examine whether inequities change following the legalization of recreational cannabis in Canada.

Opioid toxicity deaths in Black persons who experienced provincial incarceration in Ontario, Canada 2015-2020: A population-based study.

OBJECTIVE: In the context of mass incarceration and the opioid toxicity crisis in North America, there is a lack of data on the burden of opioid toxicity deaths in Black persons who experience incarceration. We aimed to describe absolute and relative opioid toxicity mortality for Black persons who experienced incarceration in Ontario, Canada between 2015 and 2020. METHODS: We linked data for all persons incarcerated in provincial correctional facilities and all persons who died from opioid toxicity in Ontario between 2015 and 2020, and accessed public data on population sizes. We described the characteristics of Black persons who were incarcerated and died from opioid toxicity, and calculated absolute mortality rates, as well as age-standardized mortality rates compared with all persons in Ontario not incarcerated during this period. RESULTS: Between 2015 and 2020, 0.9% (n = 137) of 16,177 Black persons who experienced incarceration died from opioid toxicity in custody or post-release, for an opioid toxicity death rate of 0.207 per 100 person years. In the two weeks post-release, the opioid toxicity death rate was 1.34 per 100 person years. Standardized for age and compared with persons not incarcerated, the mortality ratio (SMR) was 17.8 (95%CI 16.4-23.1) for Black persons who experienced incarceration. CONCLUSIONS: We identified a large, inequitable burden of opioid toxicity death for Black persons who experience incarceration in Ontario, Canada. Work is needed to support access to culturally appropriate prevention and treatment in custody and post-release for persons who are Black, and to prevent incarceration and improve determinants of health.

Correlates of driving after cannabis use in high school students.

Driving under the influence of cannabis is a growing public health concern among young people. This study assessed the prevalence of cannabis-impaired driving and its related sociodemographic, psychological, and knowledge-based correlates among Canadian adolescents. The sample for this study were drawn from the 2017 Ontario Student Health and Drug Use Survey (OSDUHS), consisting of high school students with valid driver's licenses (mean age = 16.8, SD = 0.71) who were asked about their driving behaviors, drug use, and attitudes regarding cannabis use (N = 1161). A multivariable logistic regression model was performed to determine the strongest correlates of driving after cannabis use. The prevalence of past-year driving within an hour of cannabis use was 10.3% (95% CI: 7.8,13.5). In the final multivariable model, probable cannabis dependence (OR = 12.7, 95%CI: 3.4,47.7), low perceived risk of cannabis use (OR = 5.3, 95%CI: 2.5,11.1), pro-legalization attitudes, (OR = 4.3, 95%CI: 2.0,9.1) and male gender (OR = 2.6, 95%CI: 1.5,4.5) were significantly associated with driving under the influence of cannabis. Other correlates of driving after cannabis user were risky driving behaviors, including past-year texting and driving and driving after alcohol use. There are various correlates of driving under the influence of cannabis, including attitudes related to cannabis which may be amenable to intervention. Future efforts should continue to monitor the prevalence of cannabis-impaired driving in this population and determine whether changes in students' attitudes surrounding cannabis are linked to behavioural changes.

Interactions between Police and Persons Who Experience Homelessness and Mental Illness in Toronto, Canada: Findings from a Prospective Study.

OBJECTIVE: We aimed to describe interactions between police and persons who experience homelessness and serious mental illness and explore whether housing status is associated with police interactions. METHOD: We conducted a secondary analysis of 2008 to 2013 data from the Toronto, Canada, site of the At Home/Chez Soi study. Using police administrative data, we calculated the number and types of police interactions, the proportion of charges for acts of living and administration of justice, and the proportion of occurrences due to victimization, involuntary psychiatric assessment, and suicidal behavior. Using generalized estimating equations, we estimated the odds of police interaction by housing status. RESULTS: This study included 547 adults with mental illness who were homeless at baseline. In the year prior to randomization, 55.8% of participants interacted with police, while 51.7% and 43.0% interacted with police in Study Years 1 and 2, respectively. Of 2,228 charges against participants, 12.6% were due to acts of living and 21.2% were for administration of justice. Of 518 occurrences, 41.1% were for victimization, 45.6% were for mental health assessment, and 22.2% were for suicidal behavior. The odds of any police interaction during the past 90 days was 47% higher for those who were homeless compared to those who were stably housed (95% CI 1.26 to 1.73). CONCLUSIONS: For people who experience homelessness and mental illness in Toronto, Canada, interactions with police are common. The provision of stable housing and changes in policy and practice could decrease harms and increase health benefits associated with police interactions for this population.

Ethnoracial differences in cannabis use among native-born and foreign-born high school students in Ontario.

The objective of this study was to examine the association of ethnoracial background and immigrant status to cannabis use among students in Ontario, Canada. Data were derived from the Ontario Student Drug Use and Health Survey, a school-based, province-wide survey of students in Grades 7-12. The survey utilized a stratified two-stage cluster design. Analyses were based on a pooled subsample of 12,527 students in Grades 9-12 during the 2011 and 2013 survey cycles and included adjustments for the complex sample design. Results indicate that youth who were of South Asian or East/Southeast Asian background were at lower odds of cannabis use than those who were White, Black, or mixed-race backgrounds. Youth who were of mixed-race background (i.e., White and another group) were at higher odds of cannabis use than youth who were of White background. The association between ethnoracial background and cannabis use also varied for some foreign-born and native-born youth. These findings suggest that ethnoracial background should be an important consideration in investigations of cannabis use among foreign- relative to native-born youth.

Years of life lost to incarceration: inequities between Aboriginal and non-Aboriginal Canadians.

BACKGROUND: Aboriginal representation in Canadian correctional institutions has increased rapidly over the past decade. We calculated "years of life lost to incarceration" for Aboriginal and non-Aboriginal Canadians. METHODS: Incarceration data from provincial databases were used conjointly with demographic data to estimate rates of incarceration and years of life lost to provincial incarceration in (BC) and federal incarceration, by Aboriginal status. We used the Sullivan method to estimate the years of life lost to incarceration. RESULTS: Aboriginal males can expect to spend approximately 3.6 months in federal prison and within BC spend an average of 3.2 months in custody in the provincial penal system. Aboriginal Canadians on average spend more time in custody than their non-Aboriginal counterparts. The ratio of the Aboriginal incarceration rate to the non-Aboriginal incarceration rate ranged from a low of 4.28 in Newfoundland and Labrador to a high of 25.93 in Saskatchewan. Rates of incarceration at the provincial level were highest among Aboriginals in Manitoba with an estimated rate of 1377.6 individuals in prison per 100,000 population (95% confidence interval [CI]: 1311.8-1443.4). CONCLUSIONS: The results indicate substantial differences in life years lost to incarceration for Aboriginal versus non-Aboriginal Canadians. In light of on-going prison expansion in Canada, future research and policy attention should be paid to the public health consequences of incarceration, particularly among Aboriginal Canadians.

Distribution of legal retail cannabis stores in Canada by neighbourhood deprivation.

OBJECTIVES: In legal cannabis markets, the distribution of retail stores has the potential to influence transitions from illegal to legal sources as well as consumer patterns of use. The current study examined the distribution of legal cannabis stores in Canada according to level of neighbourhood deprivation. METHODS: Postal code data for all legal cannabis stores in Canada were collected from government websites from October 2018 to September 2021. This data was linked to the Institut National de Santé Publique du Québec measures for material and social neighbourhood deprivation. Descriptive data are reported, including differences across provinces with different retail systems. RESULTS: At the national level, there were approximately 8.0 retail cannabis stores per 100,000 individuals age 15+ in September 2021. The distribution of stores was closely aligned with the expected distribution across levels of material deprivation: for example, 19.5% of stores were located in neighbourhoods with the lowest level of material deprivation versus 19.1% in the highest level. More cannabis stores were located in the 'most socially deprived' or 'socially deprived' neighbourhoods (37.2% and 22.1%, respectively), characterized by a higher proportion of residents who live alone, are unmarried, or in single-parent families. The distribution of stores in provinces and territories were generally consistent with national patterns with a few exceptions. CONCLUSION: In the first 3 years following cannabis legalization in Canada, retail cannabis stores were evenly distributed across materially deprived neighbourhoods but were more common in socially deprived neighbourhoods. Future monitoring of retail store locations is required as the legal retail market evolves in Canada.

Patterns of problematic cannabis use in Canada pre- and post-legalisation: Differences by neighbourhood deprivation, individual socioeconomic factors and race/ethnicity.

INTRODUCTION: The legalisation of cannabis in Canada in 2018, and subsequent increase in prevalence of use, has generated interest in understanding potential changes in problematic patterns of use, including by socio-demographic factors such as race/ethnicity and neighbourhood deprivation level. METHODS: This study used repeat cross-sectional data from three waves of the International Cannabis Policy Study web-based survey. Data were collected from respondents aged 16-65 prior to cannabis legalisation in 2018 (n = 8704), and post-legalisation in 2019 (n = 12,236) and 2020 (n = 12,815). Respondents' postal codes were linked to the INSPQ neighbourhood deprivation index. Multinomial regression models examined differences in problematic use by socio-demographic and socio-economic factors and over time. RESULTS: No evidence of a change in the proportion of those aged 16-65 in Canada whose cannabis use would be classified as 'high risk' was noted from before cannabis legalisation (2018 = 1.5%) to 12 or 24 months after legalisation (2019 = 1.5%, 2020 = 1.6%; F = 0.17, p = 0.96). Problematic use differed by socio-demographic factors. For example, consumers from the most materially deprived neighbourhoods were more likely to experience 'moderate' vs 'low risk' compared to those living outside deprived neighbourhoods (p < 0.01 for all). Results were mixed for race/ethnicity and comparisons for high risk were limited by small sample sizes for some groups. Differences across subgroups were consistent from 2018 to 2020. DISCUSSION AND CONCLUSIONS: The risk of problematic cannabis use does not appear to have increased in the 2 years following cannabis legalisation in Canada. Disparities in problematic use persisted, with some racial minority and marginalised groups experiencing higher risk.

Overpoliced and Underrepresented: Perspectives on Cannabis Legalization From Members of Racialized Communities in Canada.

Historically, overpolicing of some racialized and Indigenous groups in Canada has resulted in unequal application of drug laws contributing to disproportionate rates of charges and convictions in these populations. Criminal records severely and negatively impact an individual's life and can perpetuate cycles of poverty and socioeconomic disadvantage. On October 17, 2018, Canada legalized cannabis production, distribution, sale, and possession for non-medical purposes. Advocates of criminal justice reform have raised concerns that Indigenous and racialized people may not equitably benefit from legalization due to unequal police surveillance and drug enforcement. These groups are among priority populations for research on cannabis and mental health, but their views on cannabis regulation have been largely absent from research and policy-making. To address this gap, we asked self-identified members of these communities about their lived experiences and perspectives on cannabis legalization in Canada. Between September 2018 and July 2019, we conducted semistructured interviews and focus groups with 37 individuals in Québec, Ontario, Alberta and British Columbia. During this phase of early cannabis legalization, participants responded to questions about anticipated public health risks and benefits of legalization, how their jurisdiction is responding to legalization, and what community resources would be needed to address legalization impacts. We conducted a thematic analysis and identified five major themes in the data related to race and early cannabis legalization: overpolicing of racialized communities, severity of penalties in new cannabis legislation, increased police powers, and underrepresentation of racialized groups in the legal cannabis market and in cannabis research. Participants discussed opportunities to support cannabis justice, including establishing priority licenses, issuing pardons or expunging criminal records, and reinvesting cannabis revenue into impacted communities. This work begins to address the paucity of Indigenous and racialized voices in cannabis research and identifies potential solutions to injustices of cannabis prohibition.

Burden of opioid toxicity death in the fentanyl-dominant era for people who experience incarceration in Ontario, Canada, 2015-2020: a whole population retrospective cohort study.

OBJECTIVES: To describe mortality due to opioid toxicity among people who experienced incarceration in Ontario between 2015 and 2020, during the fentanyl-dominant era. DESIGN: In this retrospective cohort study, we linked Ontario coronial data on opioid toxicity deaths between 2015 and 2020 with correctional data for adults incarcerated in Ontario provincial correctional facilities. SETTING: Ontario, Canada. PARTICIPANTS: Whole population data. MAIN OUTCOMES AND MEASURES: The primary outcome was opioid toxicity death and the exposure was any incarceration in a provincial correctional facility between 2015 and 2020. We calculated crude death rates and age-standardised mortality ratios (SMR). RESULTS: Between 2015 and 2020, 8460 people died from opioid toxicity in Ontario. Of those, 2207 (26.1%) were exposed to incarceration during the study period. Among those exposed to incarceration during the study period (n=1 29 152), 1.7% died from opioid toxicity during this period. Crude opioid toxicity death rates per 10 000 persons years were 43.6 (95% CI=41.8 to 45.5) for those exposed to incarceration and 0.95 (95% CI=0.93 to 0.97) for those not exposed. Compared with those not exposed, the SMR for people exposed to incarceration was 31.2 (95% CI=29.8 to 32.6), and differed by sex, at 28.1 (95% CI=26.7 to 29.5) for males and 77.7 (95% CI=69.6 to 85.9) for females. For those exposed to incarceration who died from opioid toxicity, 10.6% died within 14 days of release and the risk was highest between days 4 and 7 postrelease, at 288.1 per 10 000 person years (95% CI=227.8 to 348.1). CONCLUSIONS: The risk of opioid toxicity death is many times higher for people who experience incarceration compared with others in Ontario. Risk is markedly elevated in the week after release, and women who experience incarceration have a substantially higher SMR than men who experience incarceration. Initiatives to prevent deaths should consider programmes and policies in correctional facilities to address high risk on release.

Race, cannabis and the Canadian war on drugs: An examination of cannabis arrest data by race in five cities.

BACKGROUND: The enforcement of drug laws in the United States has been heavily racialized. A substantial proportion of individuals arrested and prosecuted for drug possession in America are Black and Latino, despite similar rates of drug use across racial groups. Due to a lack of access to racially disaggregated criminal justice data, little is known about how race influences drug law enforcement in Canada. METHODS: We conducted an analysis of cannabis arrest data obtained from police services in five Canadian cities (Vancouver, Calgary, Regina, Ottawa, Halifax) to determine whether racial differences exist in rates of arrest for minor cannabis possession in Canada. RESULTS: With just one exception, we find that both Black and Indigenous people are over-represented amongst those arrested for cannabis possession across the five cities examined. CONCLUSIONS: Canadian cannabis legalization lacks measures to redress the racialized harms caused by the war on drugs because the full extent of these harms remains largely unknown. Broader collection and dissemination of disaggregated criminal justice data is needed in the Canadian context in order to inform criminal justice and social policy.
