Ohio: New Daily Purchase Limits for Recreational Marijuana Sales Start June 4

The Division of Cannabis Control has issued updated guidance establishing daily purchase limits for non-medical marijuana sales in Ohio, with the rules taking effect June 4.

Under the new rules, adults 21 and older will be limited to buying 2.5 ounces of vaporization-ready cannabis flower per day. In addition, consumers will be allowed to purchase up to 15,000 milligrams of total THC per day in non-plant products such as edibles, tinctures, and vape cartridges. For example, a 500 mg vape and a 100 mg pack of gummies would count as 600 mg toward the 15,000 mg cap.

These limits apply only to recreational consumers. Medical marijuana patients will continue to operate under the state’s 90-day supply system, and dispensaries are required to prioritize inventory access for those patients. The Division emphasized that while dispensaries are allowed to dispense up to the statutory maximum, they are not obligated to do so.

Study: Long-Term CBD Treatment Improves Memory and Reduces Brain Inflammation

New research published in the journal Frontiers in Aging Neuroscience finds that daily cannabidiol (CBD) treatment may help slow cognitive decline in aging, without impairing motor skills or causing negative side effects.

Researchers from the University of Lethbridge and McGill University studied the impact of CBD in an animal model over a seven-month period. Starting at 14 months of age—roughly the equivalent of middle age in humans—mice were administered daily oral doses of CBD until they were 21 months old. They were then evaluated using a variety of cognitive and behavioral tests.

Mice that received CBD demonstrated notable improvements in memory. In the novel object recognition (NOR) task, CBD-treated mice explored new objects more consistently than control animals, indicating better long-term memory retention. Spatial memory was also enhanced: in the Morris water maze task, CBD-treated mice spent more time in the target quadrant during probe trials, suggesting better recall of the platform’s location. However, CBD had no measurable impact on motor function or balance.

Study: Full Spectrum Cannabis Oil and Omega-3 Fatty Acids May Alleviate Neuropathic Pain and Prevent Nerve Damage

According to a study published in the Journal of Pharmacy and Pharmacology, combining CBD-enriched cannabis oil with omega-3 fatty acids may offer an effective strategy for managing neuropathic pain and promoting nerve recovery.

Conducted by researchers in Argentina from the University of La Rioja, the National University of Córdoba, and Dr. Enrique Vera Barros Regional Hospital, the study used established rat models to test both acute and chronic pain responses.

The researchers evaluated thermal and mechanical hypersensitivity using the hot plate test and the chronic constriction injury (CCI) model, respectively. They also assessed motor function and nerve damage through walking track analysis, the rotarod test, and histological examination of sciatic nerves.

Study: Researchers Identify Major Genetic Markers Driving THC and CBD Production in Cannabis

Researchers from Université Laval in Quebec have mapped key genetic markers responsible for cannabinoid production in marijuana, a discovery they say could revolutionize strain development and genetic selection in the legal cannabis industry. The findings were published in Plant Genome.

Using a genome-wide association study (GWAS) on 174 marijuana strains from Canada’s legal market, the team analyzed over 282,000 single-nucleotide polymorphisms (SNPs) to identify 33 markers linked to the production of 11 cannabinoids, including THC, CBD, CBDA, THCV, and CBN. The study also pinpointed 18 candidate genes, some of which contain variants that alter protein function in ways that may affect how much THC or CBD a plant produces.

Among the most important discoveries was a massive haplotype—a block of genes that are inherited together—on chromosome 7. This haplotype was present in roughly 95% of THC-dominant (Type I) strains and is strongly associated with high THC content and the absence of CBD. The findings support a codominant inheritance model in which certain allele combinations determine whether a plant is THC-dominant, CBD-dominant, or produces a balanced mix.

Washington D.C. Breaks Medical Cannabis Sales Record in April

Washington D.C.’s medical marijuana market hit a new milestone in April, with licensed dispensaries generating $5,456,393 in sales—the highest monthly total since the program launched in 2013.

The record-setting figure marks a sharp increase from the $3.67 million sold in March and nearly doubles the $2.87 million recorded in April 2024. In total, dispensaries brought in nearly $15 million during the first four months of 2025.

The jump in revenue comes as patient participation continues to climb. More than 33,000 patients made purchases from a licensed dispensary in April, including over 16,000 D.C. residents, nearly 14,000 self-certified out-of-state patients, and more than 3,000 reciprocity patients.

Texas Senate Approves Legislation to Ban Hemp-Derived THC Products, Sending Bill to Governor Abbott

The Texas Senate voted tonight to approve Senate Bill 3, which would ban hemp-derived THC products, sending the measure to Governor Greg Abbott for consideration.

Hemp THC gummies.

SB 3, which previously passed the Senate in March, was passed this week by the full House. Given the House approved amendments to the bill, it went back to the Senate for final approval, which they gave Sunday night.

The proposed law would outlaw most edibles, beverages, tinctures, and vape products that contain any meaningful amount of THC, with limited exceptions for trace-level products. The House had initially sought to revise the bill to create a regulatory framework for these products. However, a floor amendment reversed that approach, returning it to the Senate as a ban similar to the original Senate version.

Study: CBD Nanoemulsion May Alleviate Parkinson’s Symptoms and Intestinal Damage

A new preclinical study finds that a cannabidiol (CBD) nanoemulsion could protect against both brain and gut damage caused by Parkinson’s disease, while also improving behavior and reducing inflammation.

Published in the European Journal of Pharmacology, the study was conducted by researchers at the Federal University of Ceará in Brazil. It used a rat model of Parkinson’s disease induced by the toxin rotenone, which mimics the disease’s characteristic neurodegeneration, including the buildup of α-synuclein and increased oxidative stress.

Rats exposed to rotenone experienced significant motor and cognitive impairments, elevated oxidative stress, and reductions in glutathione, an important antioxidant. They also showed increased α-synuclein accumulation and inflammation not only in the brain but also in the intestine—a common site of dysfunction in Parkinson’s patients.

Study: 3D-Printed CBD Stent Shows Promise for Localized Urinary Tract Infection (UTI) Treatment

According to a new study, researchers have developed a 3D-printed stent designed to treat urinary tract infections (UTIs) using cannabidiol (CBD), potentially offering a targeted alternative to conventional antibiotic therapy.

The study, published in the International Journal of Pharmaceutics, was conducted by scientists from the University of Bern in Switzerland and the University of Rome in Italy. The researchers created a customizable stent made of a laponite-alginate hydrogel and infused it with CBD-loaded PLGA microparticles to allow for controlled and sustained drug release. The stent, tailored for the female urethra, was engineered to maintain structural integrity for at least 14 days under simulated physiological conditions, delivering localized CBD directly to the site of infection.

In laboratory testing, the device demonstrated prolonged antimicrobial activity against both Gram-positive and Gram-negative bacteria. Researchers say this targeted approach could reduce the need for systemic antibiotics, potentially lowering the risk of side effects and improving adherence while helping combat the global issue of antibiotic resistance.

First Recreational Marijuana Store Outside Tribal Land Opens in Minnesota

Minnesota’s first recreational marijuana store not located on tribal land is now open in the city of Moorhead.

Operated by the White Earth Nation, the store is part of a broader agreement signed with Governor Tim Walz that allows the tribe to open up to eight marijuana retail locations across the state. The agreement makes White Earth the first tribal nation in Minnesota to launch adult-use marijuana stores outside of its reservation.

“This is a historic moment for Minnesota and for White Earth,” said Zach Wilson, CEO of Waabigwan Mashkiki, which operates the Moorhead store. “We’re proud to be the first adult-use dispensary open in the state.”

Texas Senate Committee Drastically Pares Back House-Approved Medical Marijuana Expansion Bill

A Texas Senate committee has quietly approved new language for House Bill 46 that significantly rolls back a proposed expansion of the state’s Compassionate Use Program (TCUP), eliminating chronic pain and traumatic brain injury (TBI) from the list of qualifying conditions and cutting the number of new business licenses by two-thirds.

The revised bill, approved during a Senate State Affairs Committee hearing Friday night, now heads to the full Senate for a vote. If passed, it will need to be reconciled with the more expansive House version before going to Governor Greg Abbott.

The move is expected to upset House lawmakers who backed the controversial ban on hemp-derived THC product, which recently passed the full House, with the understanding that medical marijuana access would be broadened—particularly for veterans and other patients with serious health conditions.
