Ohio’s legal marijuana market has generated an estimated $914.3 million in combined medical and adult-use sales so far in 2026, bringing all-time sales to nearly $4.3 billion. Updated Division of Cannabis Control data show adult-use purchases accounted for roughly $785 million of this year’s total, or about 86%, with nearly 50 million transactions completed since legal sales began.

The Federal Reserve is proposing guidance that specifically identifies marijuana businesses as an example of higher-risk bank customers that may require more advanced anti-money-laundering monitoring tools. The nonbinding proposal applies to traditional community banks with less than $30 billion in assets and does not create new requirements. Public comments on the community-bank guidance are being accepted through November 16.

The federal government plans to update marijuana questions in the 2027 National Survey on Drug Use and Health, replacing references to “smoking marijuana” with broader language meant to account for vaping, edibles and other consumption methods. The Substance Abuse and Mental Health Services Administration is accepting public comments on the proposed changes through November 16.

A New Jersey bill would require licensed marijuana retailers to conspicuously display point-of-sale warnings about health risks associated with high-potency products. Assembly Bill 5463 would direct the Cannabis Regulatory Commission to define “high potency” and develop the notice, including warnings for people under 25 and those with or at risk of certain mental health conditions or psychotic disorders.

A new Elon University Poll finds 80% of North Carolina likely voters support legalizing medical marijuana, while 57% support recreational legalization. Among all adults surveyed, 75% backed medical use and 55% supported recreational use. The poll also found 53% favor allowing intoxicating hemp-derived THC products, while 82% support banning sales of those products to people under 21.

The Marijuana Herald has compiled 50 cannabis and cannabinoid studies published in 2026 examining cancer, cancer treatment and related symptoms. The research spans breast, brain, lung, pancreatic, prostate, blood and other cancers and includes laboratory studies, animal research, reviews and human studies. Much of the evidence remains preclinical, but the volume highlights broad scientific interest in cannabinoids and cancer.

The U.S. Court of Appeals for the Third Circuit has ruled that police generally need a warrant supported by probable cause before strip-searching an arrestee who is not being admitted to a jail’s general population. The case stemmed from a Pennsylvania marijuana arrest in which officers searched a man twice, found nothing, then transported him to a station solely for a strip search.

California marijuana regulators have revised proposed plant-tagging rules to allow cultivators to track groups containing multiple strains or cultivars under a single tag. The Department of Cannabis Control says the broader group-tagging proposal could reduce costs and administrative burdens while maintaining track-and-trace oversight. Public comments on the revised language are being accepted through October 2.

Delaware Governor Matt Meyer has signed House Bill 411, formally renaming the Division of Alcohol and Tobacco Enforcement as the Division of Alcohol, Tobacco, and Marijuana Enforcement. The change took effect immediately and reflects marijuana enforcement duties the agency already performs as Delaware’s adult-use market develops. The legislation does not grant new enforcement powers and will be funded through the Marijuana Regulation Fund.

A human study involving 31 patients found a full-spectrum, CBD-dominant cannabis oil was associated with significant reductions in chronic pain and anxiety after three months. Patients also reported improvements in mood, sleep and overall health, and no adverse events were reported. Researchers cautioned that the small, uncontrolled study cannot establish causation and called for larger randomized trials.

Oregon alcohol businesses have been more than four times as likely as marijuana stores to sell to underage decoys during 2026 compliance checks, according to a Marijuana Herald analysis of state data. Alcohol businesses failed 17.9% of checks through August 28, compared with 4.2% for marijuana retailers. The disparity remained nearly as large when the analysis was limited to random inspections.

Representatives Nydia Velázquez and Warren Davidson have reintroduced the bipartisan CLAIM Act, which would provide federal protections for insurers serving state-legal marijuana businesses. The measure would prevent federal agencies from penalizing insurers solely for working with qualifying marijuana companies and would extend protections to agents and brokers. A companion CLAIM Act is already pending in the U.S. Senate.

A review of 19 peer-reviewed studies found CBD may help protect skin cells from some effects of ultraviolet radiation by reducing oxidative stress and inflammation and supporting cellular antioxidant pathways. The review, published in Archives of Dermatological Research, included laboratory, animal and human research. Authors said CBD warrants further study as a possible addition to photoprotective products, not as a substitute for sunscreen.

North Dakota will sharply increase certification fees for medical marijuana businesses beginning November 1. Processor-only facilities will see the largest jump, from $20,000 to $50,000, a 150% increase. Production-only manufacturing facilities will rise to $70,000, dispensaries to $90,000 and full manufacturing facilities to $110,000 under updated regulations adopted by the Department of Health and Human Services.

A study published in the Journal of Pharmacology and Experimental Therapeutics found THC significantly suppressed inflammatory activity in human CD8+ T cells, including interferon gamma, interleukin-2 and tumor necrosis factor alpha. Researchers say the mechanism could be relevant to HIV-associated neurocognitive disorder, although the findings do not show that THC or marijuana can treat cognitive decline in patients.
