RESUMO
The increasing contamination of the drug supply with illicitly manufactured fentanyl and related analogs in North America has resulted in the most severe drug-overdose crisis in history. Available pharmacotherapy options for the treatment of opioid use disorder have had limited success in curbing the current crisis, and a growing body of evidence highlights the need for innovative interventions that target underlying social-structural drivers of opioid use disorder. Re-emerging clinical research suggests that psychedelic-assisted therapy has potential as an alternative treatment for refractory substance use disorders and related comorbidities. Based on the available evidence, our viewpoint supports advancing research on the potential role of psychedelic-assisted therapy within a multifaceted response to the opioid crisis.

Adulteration of illicit drug supplies with synthetic opioids such as fentanyl has contributed to a dramatic rise in overdose morbidity and mortality in North America. One promising response to this crisis is the implementation of "drug checking" services. Drug checking encompasses a range of interventions used to assess the constituents of illicit drug samples, such as colour-spot testing, gas or liquid chromatography, and various methods of spectroscopy. Testing may be performed on-site at events or harm reduction service locales, performed independently by consumers, or sent to a centralized lab for analysis. This information may then serve to inform individual decision-making, enhance harm reduction efforts and strengthen public health surveillance and response strategies to prevent harms associated with illicit drug use. Historical examples of drug checking services that emerged with the 1990s synthetic "party drug" movement in Europe provide a theoretical and practical basis for the adaptation of these services for use in context of the current opioid overdose crisis. Potential harm reduction benefits of drug checking for synthetic opioid adulterants include individuals being more likely to use drugs more safely or to dispose of drugs found to contain harmful adulterants. Public health benefits of drug checking may also include negative feedback on the illicit drug supply with decreased availability or consumption of drugs from sources adulterated with synthetic opioids following public health warning campaigns. As part of the response to the current synthetic opioid epidemic in BC, pilot efforts are being undertaken in Vancouver to determine the feasibility and effectiveness of drug checking as an overdose response strategy. Models of drug checking service delivery and comparison of differing technologies, including unique challenges and potential solutions related to access to these services, legal obstacles, and sensitivity and specificity of testing technologies, are explored, alongside suggestions for future research and directions.

BACKGROUND: Access to harm reduction interventions among substance users across Canada is highly variable, and largely within the policy jurisdiction of the provinces and territories. This study systematically described variation in policy frameworks guiding harm reduction services among Canadian provinces and territories as part of the first national multimethod case study of harm reduction policy. METHODS: Systematic and purposive searches identified publicly-accessible policy texts guiding planning and organization of one or more of seven targeted harm reduction services: needle distribution, naloxone, supervised injection/consumption, low-threshold opioid substitution (or maintenance) treatment, buprenorphine/naloxone (suboxone), drug checking, and safer inhalation kits. A corpus of 101 documents written or commissioned by provincial/territorial governments or their regional health authorities from 2000 to 2015 were identified and verified for relevance by a National Reference Committee. Texts were content analyzed using an a priori governance framework assessing managerial roles and functions, structures, interventions endorsed, client characteristics, and environmental variables. RESULTS: Nationally, few (12%) of the documents were written to expressly guide harm reduction services or resources as their primary named purpose; most documents included harm reduction as a component of broader addiction and/or mental health strategies (43%) or blood-borne pathogen strategies (43%). Most documents (72%) identified roles and responsibilities of health service providers, but fewer declared how services would be funded (56%), specified a policy timeline (38%), referenced supporting legislation (26%), or received endorsement from elected members of government (16%). Nonspecific references to 'harm reduction' appeared an average of 12.8 times per document-far more frequently than references to specific harm reduction interventions (needle distribution=4.6 times/document; supervised injection service=1.4 times/document). Low-threshold opioid substitution, safer inhalation kits, drug checking, and buprenorphine/naloxone were virtually unmentioned. Two cases (Quebec and BC) produced about half of all policy documents, while 6 cases - covering parts of Atlantic and Northern Canada - each produced three or fewer. CONCLUSION: Canada exhibited wide regional variation in policies guiding the planning and organization of Canadian harm reduction services, with some areas of the country producing few or no policies. Despite a wealth of effectiveness and health economic research demonstrating the value of specific harm reduction interventions, policies guiding Canada from 2000 to 2015 did not stake out harm reduction interventions as a distinct, legitimate health service domain.
