A new study from the University of Alabama at Birmingham’s Heersink School of Medicine suggests that individuals who use cannabis are not necessarily less physically active than non-users. Instead, the findings indicate a tendency to favour light or moderate exercise, pointing to a potential influence of cannabis on the subjective experience of physical activity.
May 28, 2026	Raid on Victoria Cannabis Buyer’s Club raises questions around medical cannabis access On April 21 the Victoria Cannabis Buyer’s Club (VCBC) was raided by B.C.’s Community Safety Unit (CSU), supported by Victoria Police. Shortly after the “compassion club” opened their doors, CSU officers entered the Johnson Street storefront and confiscated approximately 30 000 to 40 000 cannabis products, said Club Founder and President Ted Smith. The club had just recently celebrated its 30th anniversary in January. Smith described the three decade journey like “climbing a series of mountains.” He established the group in 1996, inspired by the San Francisco Buyers Club and Victoria activists’ work providing cannabis to AIDS patients.

May 28, 2026	Minnesota Governor Walz Signs Landmark Cannabis Omnibus Bill, Reshaping State’s Cannabis Industry On May 26, 2026, the Minnesota Governor Tim Walz signed into law the 2026 Omnibus Cannabis Bill. Sponsored by Representative Jessica Hanson (DFL-Burnsville), the law represents a sweeping set of reforms to the state’s regulated cannabis industry, touching everything from medical cannabis access and supply chain logistics to hemp-industry lifelines and a brand-new license category. Representative Hanson described it as a “collaborative effort” involving more than 80 stakeholders and weekly meetings over the course of three months. Here is a breakdown of the law’s most significant provisions and what they mean for Minnesota’s cannabis landscape. Merging the Medical and Adult-Use Supply Chains Perhaps the most consequential change in the law is the merger of Minnesota’s currently bifurcated medical and adult-use cannabis supply chains. Under current law, cannabis businesses that participate in both markets must maintain separate cultivation, manufacturing, and inventory tracking systems—including separate instances within the state’s Metrc seed-to-sale tracking platform. The omnibus bill eliminates this dual-track requirement and allows businesses with a medical cannabis endorsement to serve patients and adult-use customers from a single, unified operation.
May 28, 2026	How the UK’s medical cannabis sector is reshaping modern healthcare access The UK’s medical cannabis sector has changed dramatically since cannabis-based medicinal products were legalized for specialist prescription use in 2018. What initially appeared to many observers as a limited and highly cautious policy shift has gradually evolved into a growing healthcare sector shaped by digital clinics, increasing patient demand, and broader public awareness surrounding alternative treatment pathways. While the UK still operates under tightly regulated prescribing structures, the overall landscape in 2026 looks very different from the early years following legalization. Private clinics have expanded rapidly, telehealth systems have modernized patient access, and conversations surrounding specialist cannabis treatment have become increasingly normalized within wider healthcare discussions.

A study conducted by the University of Geneva (UNIGE), in collaboration with the Swiss Center for Applied Human Toxicology (SCAHT), provides a new answer by showing that cannabis use does not reduce testosterone levels in young men and may even increase its testicular synthesis.
May 27, 2026	Germany Imported Over 218 Tons of Legal Cannabis in One Year When it comes to Europe’s emerging legal cannabis industry, Germany continues to stand alone as the undisputed continental leader.

May 27, 2026	New Jersey court lets job seekers sue employers over cannabis tests New Jersey job seekers can now sue employers directly over a rescinded offer tied to a positive cannabis test. That's the headline takeaway from a New Jersey Appellate Division ruling issued on May 26, 2026, in Darlene Sanders v. The Levari Group, LLC, doing business as First Choice Freezer. As a matter of first impression, the court found that the state's Cannabis Regulatory, Enforcement Assistance, and Market Modernization Act, or CREAMMA, gives applicants the right to sue employers who reject them because of cannabis use.
May 27, 2026	Recreational Cannabis Legalization and Traffic Fatality Rates in the United States, 2005-2024: An Imputation-Based Difference-in-Differences Event Study Conclusion Legalizing recreational cannabis was followed by a rise in traffic deaths during the first four years after the law took effect. The increase began at legalization rather than at the start of retail sales. This suggests that the change in law and shifting public attitudes had a greater impact on traffic safety than the availability of cannabis in stores. States considering legalization should prepare traffic safety measures in advance, while those that have already legalized should reinforce existing efforts to address ongoing risks.
May 27, 2026	$2.56 Billion in Farm Receipts Marks Largest Increase in Cannabis Production Since 2020 The Canadian cannabis sector experienced significant growth in 2025, with farm receipts increasing 16.9% to $2.56 billion and total recreational sales reaching $5.5 billion. Cannabis producers also appeared to be setting aside more cannabis in storage in 2025. Government revenue from the industry rose to $2.5 billion, while the market continued to shift toward inhaled extracts, which accounted for nearly one-third of all sales. Despite a general sales slowdown compared to previous years, retail figures remained strong, highlighted by a 6% year-over-year increase in March 2026.

May 27, 2026	How Policy Changes and the Pandemic Reshaped Teen Cannabis Use A recent study, published online in JAMA Network Open, examined more than 1.3 million screenings of Northern California adolescents from 2011–2024 to understand how cannabis use changed after legalization and during the COVID-19 pandemic. Rates of adolescent cannabis use had been steadily declining before California legalized recreational cannabis in 2016, but began increasing after the law passed—before retail stores even opened—suggesting shifts in social norms, perceived risk, and normalization rather than access alone. Rates continued to rise modestly after legal sales began in 2018.

May 26, 2026	Indiana Officials Await Federal Action on Marijuana Indiana legislators may soon return to discussions surrounding medical cannabis, though state officials say there is still uncertainty about whether federal action will prompt any immediate changes in state policy. During a meeting on May 11, members of the Indiana Board of Pharmacy examined a federal notice concerning cannabis rescheduling. However, the board did not move forward with any decisions, emphasizing that Indiana would only consider a response once the federal government formally completes the process. As a result, existing cannabis laws in the state remain intact for the time being.
