Police seizure of drugs without arrest among people who use drugs in Vancouver, Canada, before provincial 'decriminalization' of simple possession: a cohort study.

BACKGROUND: Several jurisdictions in Canada have recently considered decriminalizing possession of illicit drugs for personal use (henceforth, simple possession) as part of their responses to the ongoing drug toxicity/overdose crisis. In this context, we sought to examine an early implementation case of a de facto depenalization policy of simple possession offences in Vancouver, Canada, that was enacted in 2006. Specifically, we characterized experiences of people who use drugs (PWUD) whose drugs were discretionally seized by police without arrest. METHODS: Data were derived from three prospective cohorts of community-recruited PWUD in Vancouver over 16 months in 2019-2021. We conducted multivariable generalized estimating equations analyses to determine the prevalence of and factors associated with drug seizure. Sub-analyses used data collected in 2009-2012 and examined the trends over time. RESULTS: Among 995 participants who were interviewed in 2019-2021, 63 (6.3%) had their drugs seized by police at least once in the past 6 months. In multivariable analyses, factors significantly associated with drug seizure included: homelessness (adjusted odds ratio [AOR]: 1.98; 95% confidence interval [CI] 1.09-3.61), working in the unregulated drug market (AOR: 4.93; 95% CI 2.87-8.49), and naloxone administration (AOR: 2.15; 95% CI 1.23-3.76). In 2009-2012, 67.8% reported having obtained new drugs immediately after having their drugs seized by police. Odds of drug seizure were not significantly different between the two time periods (2019-2021 vs. 2009-2012) (AOR: 0.93; 95% CI: 0.64-1.35). CONCLUSIONS: Despite the depenalization policy, the Vancouver Police Department has continued to seize illicit drugs from PWUD, even in cases where no arrest occurred. This policing practice may create health and safety risks for PWUD as it forces PWUD to increase the engagement with the unregulated illicit drug market. Our findings support calls for abolishing this often-undocumented discretionary policing practice that may exacerbate ongoing health inequities and interfere with peer-based overdose prevention efforts.

Gridded land use data for the conterminous United States 1940-2015.

Multiple aspects of our society are reflected in how we have transformed land through time. However, limited availability of historical-spatial data at fine granularity have hindered our ability to advance our understanding of the ways in which land was developed over the long-term. Using a proprietary, national housing and property database, which is a result of large-scale, industry-fuelled data harmonization efforts, we created publicly available sequences of gridded surfaces that describe built land use progression in the conterminous United States at fine spatial (i.e., 250 m × 250 m) and temporal resolution (i.e., 1 year - 5 years) between the years 1940 and 2015. There are six land use classes represented in the data product: agricultural, commercial, industrial, residential-owned, residential-income, and recreational facilities, as well as complimentary uncertainty layers informing the users about quantifiable components of data uncertainty. The datasets are part of the Historical Settlement Data Compilation for the U.S. (HISDAC-US) and enable the creation of new knowledge of long-term land use dynamics, opening novel avenues of inquiry across multiple fields of study.

The details of decriminalization: Designing a non-criminal response to the possession of drugs for personal use.

Internationally, policymakers are considering alternative, non-criminal responses to the possession of drugs for personal use, or 'simple possession'. We show that 'decriminalization' is not a simple, unified model; rather, there are meaningful differences in policies and options available as part of a non-criminal response. Responses include various decriminalization, diversion, and depenalization approaches. However, what details need to be considered in developing these approaches? In this paper, we eschew these labels and present an overview of key design features of non-criminal responses to simple possession and consider some of the equity considerations of the choices available, including reform architecture (the objectives and legal framework); eligibility criteria (population-, place-, and drug-based criteria); and actions taken (deterrence, therapeutic, and enforcement strategies). This paper does not evaluate individual features or models, but instead offers a practical framework that can be used to deliberate on potential reform decisions.
