The COVID-19 pandemic stands to have impacts on mental health and well-being that will extend beyond its formal resolution. Before COVID-19, mental health disorders were already challenging global healthcare systems, directly accounting for 7.4% of the total burden of disease (1, 2). An estimated 1 billion people worldwide suffer from a mental health disorder, with the two most common disorders-depression and anxiety-costing the global economy US$1 trillion per year (3). Stigma and limited treatment options have amounted to substantial unmet need and violations in human rights for people with mental health disorders (1,4,5). Looking ahead, heightened postpandemic demand for mental healthcare signifies an urgent need to bolster clinical capacity by integrating novel, cost-effective approaches into existing systems (6).Emergent literature globally describes the diverse impacts of COVID-19 on mental health (7, 8). For instance, available data among hospitalized COVID-19 patients in China revealed that approximately 96% suffered post-traumatic stress symptoms (9). Studies among intensive care unit (ICU) patients with previous coronaviruses infer high rates of posttraumatic stress disorder (PTSD), depression and anxiety (30-40%) persisting months after discharge (10), with similar rates observed in patients infected with . Highly exposed individuals such as frontline healthcare workers are susceptible to similarly negative outcomes due to prolonged occupational stress, elevating risk of PTSD and suicidality (12-14). Importantly, post-pandemic mental disorders are not limited to individuals directly exposed to COVID-19. Rather, research documents PTSD symptoms among individuals who have been indirectly exposed by witnessing (e.g., via the media) or being confronted with the threat of death or serious illness (e.g., worry/anticipation about the future) (7).COVID-19 has significantly altered lives in ways that exacerbate drivers of mental health problems, with widespread uncertainty, increased experiences of grief and loss, social isolation, economic and housing instability, and decreased access to critical services related to lockdowns (6,15). Further, available data on the impacts of COVID-19 on substance use patterns indicate increased use of alcohol and other substances in response to stress and negative emotions (8,16,17). Social connections are crucial for people struggling with addiction and comorbidities such as depression, and increased social disconnection represents a key risk factor for adverse outcomes Publisher's Note: All claims expressed in this article are solely those of the authors and do not necessarily represent those of their affiliated organizations, or those of the publisher, the editors and the reviewers.

International drug policy is rapidly evolving in tandem with promising evidence for psychedelic-assisted psychotherapy (PAP) in treating a range of mental health conditions. Canada is among the countries increasingly expanding access to psychedelic substances for therapeutic purposes. The 8-year ban on medical exemptions through the Canadian Special Access Programme was recently reversed in January 2022 and the first exemptions for legal possession and personal use of psilocybin mushrooms were granted in 2020, nearly 50 years since their criminalization. In view of the evolving evidence base and regulatory landscape for PAP illustrated by recent shifts in Canadian and international drug policy, this piece seeks to clarify the special range of factors which ought to be considered to safely expand access to psychedelics. Streamlining access to safe and evidence-based compassionate use of PAP will provide a timely treatment option to those currently in need while encouraging further research and outcome surveillance to refine best practices.
