Abstract

The fentanyl-dominated recreational drug supply and the rapid rise of overdose deaths is unfortunately not the endpoint in the evolution of the North American drug market. Non-fentanyl-derived ultrapotent synthetic opioids that are several times more potent than fentanyl, such as nitazenes, are being increasingly detected in Canada and the USA. Despite having similar (and often more acute) physiological effects to heroin, these novel psychoactive substances are not well characterised, and there is little understanding of an effective treatment approach. Moreover, these new ultrapotent synthetic substances are being rapidly produced in so-called homegrown laboratories using legal and easily available precursors. Production can be established anywhere, thereby avoiding global trafficking routes, partly as an adaptation to border closures in response to the COVID-19 pandemic. These developments will challenge nearly all existing harm-reduction and treatment options, from reversing overdoses with the appropriate naloxone response to retention in opioid agonist treatment programmes, underscoring the importance of proactively collecting evidence and adjusting our health-care systems.


The inability of health-care systems to address emerging synthetic opioids exposes substantial existing inadequacies. There are too few well-established research centres that are able and ready to investigate pressing questions to guide evidence-based interventions; for example, how to best understand the influence of economic factors (eg, availability, price), societal factors (eg, stigma, health disparities), and individual factors (eg, trauma, mental health needs) in the ongoing developments. Expanding access to services and innovating treatment options specifically to address ultrapotent synthetic opioids could generate subtstantial cost savings in the long-term, which in turn could be re-invested into addiction research, health, and social services. However, beyond enhancing treatment services, could the legalisation of heroin and other substances be a successful strategy? Should there be provision of pharmaceutical grade drugs to people who are at risk of overdose, as is the case in Canada with safe supply?...
