Send us a textThis two-part episode of the CMAJ Podcast explores the roots and repercussions of medical mistrust. It begins with a historical lens, revealing echoes of today’s strained relationships between patients and the medical system, then narrows the scope to focus on a pressing clinical example.In part one, Dr. Kenneth Pinnow, a historian of Soviet medicine at Allegheny College and author of the article in CMAJ entitled Soviet medicine and the problem of public trust: 1921–1929, walks through the fraught relationship between physicians and the public in the early Soviet era. He explains how underfunding, class tensions, and unrealistic expectations resulted in widespread hostility toward physicians and fractured trust that proved difficult to repair.Part two narrows in on vaccine hesitancy, a timely example of medical distrust made more urgent by recent measles outbreaks. Dr. Noni MacDonald, a pediatric infectious disease specialist at Dalhousie University and former member of the WHO’s Strategic Advis

Send us a textOn this episode of the CMAJ Podcast, hosts Dr. Mojola Omole and Dr. Blair Bigham explore how changes to mifepristone regulation have reshaped abortion access in Ontario. Unlike most other countries, Canada allows the drug to be prescribed by any physician or nurse practitioner and dispensed by any community pharmacy, without additional restrictions or special certifications. The discussion draws on the article Changes in local access to mifepristone dispensed by community pharmacies for medication abortion in Ontario: a population-based repeated cross-sectional study, recently published in CMAJ.Dr. Laura Schummers, reproductive epidemiologist and lead author of the study, explains how the 2017 policy change contributed to a significant shift in abortion access. Before mifepristone, abortion care in Ontario was concentrated in fewer than 100 clinics, most of them in urban centres. Within five years of the regulatory change, the percentage of Ontario abortion service users with local access rose f

Send us a textThis episode of the CMAJ Podcast examines how recent changes to U.S. federal research funding are affecting the global scientific landscape—and what they could mean for Canada. The discussion focuses on indirect costs, talent retention, and whether Canada is positioned to step into any gaps left behind. The hosts speak with two guests who have written recent articles in CMAJ offering insight into how policymakers and institutions in Canada might respond.Dr. William Ghali, vice president of research at the University of Calgary, outlines how indirect research costs are funded in both countries and explains why the proposed U.S. cuts—though now on hold—would have had severe consequences for American institutions.

Send us a textA recent article in CMAJ entitled Effect of emergency department opioid prescribing on health outcomes examines a key concern facing many clinicians: can a single opioid prescription for acute pain lead to long-term harm? This study aimed to clarify the risks and inform safer prescribing practices.Dr. Grant Innes, the study’s senior author, analyzed more than a decade of data from Alberta emergency departments to compare outcomes between patients who did and did not receive an opioid prescription. The study found no significant difference in rates of overdose, opioid use disorder, or death—challenging widely held fears about short-term opioid use. Innes notes that older and opioid-naive patients may be more vulnerable to adverse outcomes and encourages a balanced approach to pain management.Dr. Hance Clarke, director of pain services at Toronto General Hospital, emphasizes the importance of structured follow-up and monitoring, especially for patients at higher risk of persistent use. He outlines

Send us a textA research article in CMAJ examines mortality risk among people hospitalized for hallucinogen use. The study found that individuals who required acute hospital care for hallucinogen-related issues had a nearly fivefold increase in mortality risk compared to the general population.Dr. Daniel Myran, a public health and preventive medicine physician, family physician, and researcher at the University of Ottawa, discusses the study’s findings and why the growing perception of psychedelics as therapeutic may be influencing increased use. He explains how individuals hospitalized for hallucinogen-related issues often have additional risk factors, including other substance use and underlying health conditions, which may contribute to their elevated mortality risk.Dr. Ishrat Husain, a senior scientist and the scientific head of the clinical trials unit at CAMH in Toronto, explores the controlled medical use of hallucinogens in treatment-resistant depression. He outlines the intensive screening and psycho

Send us a textA new CMAJ study has found that alcohol-related hospitalizations and deaths in Canada surged during the COVID-19 pandemic. While overall alcohol consumption increased only modestly, the toll on the healthcare system was severe, with a 14% rise in hospitalizations and a 24% increase in deaths during the first two years of the pandemic. Researchers suggest that increased access to alcohol—through expanded retail hours and home delivery—contributed to these harms, particularly among heavier drinkers.Dr. Tim Stockwell, a scientist at the Canadian Institute for Substance Use Research and an emeritus professor at the University of Victoria, discusses the study’s findings and why even a small rise in alcohol consumption can lead to a disproportionate increase in harm. He explains how heavier drinkers, already at risk, were pushed beyond critical health thresholds, contributing to the sharp rise in hospitalizations and deaths.Dr. Adam Sherk, a senior scientist at the Canadian Centre on Substance Use and
