Hawaii Governor Signs Expungement Bill Into Law

Hawaii Governor Josh Green has signed into law a measure to expand the state’s pilot program for automatic expungement of certain arrest records, following unanimous approval in both the Senate and House of Representatives.

The Hawaii State Capitol Building.

House Bill 132 enhances the Department of the Attorney General’s expungement pilot project—first established under Act 62 of 2024—by broadening the scope of eligible offenses. The new law allows the state to automatically expunge arrest records not only for those charged with promoting a detrimental drug in the third degree, but also for those arrested for possession of any Schedule V controlled substance in any amount, provided the case did not result in a conviction.

Supporters of the bill argue that this change removes unnecessary barriers to employment, housing and education for individuals who were never convicted of a crime. Previously, those seeking to expunge their arrest records were required to navigate a complex application process with no guaranteed access to legal assistance.

Legal Marijuana Sales Reached $2.15 Billion Across U.S. in March, Topping $6 Billion in First Quarter of 2025

In March, legal marijuana sales across 21 recreational states and two significant medical-only states—Florida and Oklahoma—totaled more than $2.1 billion.

According to data from state regulatory agencies and commission and the research firm Headset, legal marijuana states in the U.S. sold $2.15 billion worth of marijuana and marijuana products in March, a slight increase over the $2.06 billion in January and the $1.97 billion in February. This brings 2025’s total to $6.18 billion.

The list below excludes Delaware and Minnesota, both of which have legalized recreational marijuana but have not yet launched their markets, and Virginia, which has legalized marijuana possession but not commercial sales. Alaska is also omitted due to the lack of reliable sales data for March. Oklahoma and Florida are the only medical-only states included, as no other medical state had sales data available for March.

Michigan: Legal Cannabis Sales Totaled $276.9 Million in March, Prices Hit Record Low

Legal marijuana sales in Michigan reached $276,946,009.79 in March, according to a new report released by the Cannabis Regulatory Agency (CRA), with average prices dropping to an all-time low of $65.14 per ounce.

The total includes $276.4 million in adult-use sales and just over $502,000 in medical marijuana. The combined total represents a decline of about 4% from March 2024, when legal sales reached $288,843,279.77. At the same time, prices have dropped more sharply—down 28% from the $90 average seen in March of last year.

As of March 31, Michigan had 857 licensed marijuana retailers and 2,244 total licensed marijuana businesses.

Study: Delta-8-THC Produces Similar Effects to Delta-9-THC at Higher Doses, Finds Johns Hopkins Clinical Trial

A new clinical trial from Johns Hopkins University School of Medicine finds that delta-8 THC (Δ8-THC), a growingly popular hemp-derived cannabinoid, produces psychoactive effects similar to those of delta-9 THC (Δ9-THC), but only when consumed in higher doses.

The peer-reviewed study, published in the journal Drug and Alcohol Dependence, involved 19 healthy adult participants with no recent cannabinoid use. In a double-blind, crossover design, subjects were given brownies containing 10, 20, or 40 milligrams of Δ8-THC, 20 milligrams of Δ9-THC, or a placebo. Researchers then measured drug effects, blood cannabinoid levels, vital signs, and performance on cognitive and psychomotor tasks.

Results showed that Δ8-THC produced dose-dependent psychoactive effects that were qualitatively similar to those of Δ9-THC. However, the study found that 20 mg of Δ8-THC produced significantly weaker effects than an equivalent dose of Δ9-THC—including reduced intoxication, heart rate elevation, and cognitive impairment. At 40 mg, Δ8-THC’s effects were comparable to those of 20 mg of Δ9-THC.

Cannabis Callus Extract Shows Promise as Anti-Inflammatory and Antioxidant Cosmetic Ingredient, Finds Study

Researchers in South Korea have found that an extract made from in vitro-grown cannabis callus tissue may be a valuable new addition to skincare products, thanks to its strong anti-inflammatory and antioxidant effects.

The study, conducted by a team at Dongguk University and published in the journal Plants, focused on Cannabis sativa L. callus extract (CCE). Callus is a mass of unorganized plant cells often used in laboratory cultivation to produce high levels of beneficial secondary metabolites. In this case, researchers used Murashige and Skoog medium enriched with Thidiazuron (TDZ) and naphthalene acetic acid (NAA) to grow the cannabis callus.

After analyzing the extract with high-performance liquid chromatography (HPLC), the team confirmed the presence of cannabinoids. These compounds may play a role in modulating inflammation through the endocannabinoid system.

Study: Silver and Gold Nanoparticles Made From Cannabis Waste Kill Drug-Resistant Bacteria

A new study published in the Journal of Cannabis Research and indexed by the U.S. National Library of Medicine has found that silver and gold nanoparticles synthesized using cannabis waste extract have strong antibacterial effects against Pseudomonas aeruginosa, a drug-resistant bacteria commonly linked to hospital infections.

The research was conducted by scientists at the University of Chemistry and Technology in Czechia. Using a green synthesis method, they transformed marijuana plant waste into metal nanoparticles. These nanoparticles were then tested for their antimicrobial activity against Pseudomonas aeruginosa strains.

The nanoparticles were characterized using a series of advanced techniques, including transmission electron microscopy and X-ray diffraction. The researchers found that the silver nanoparticles in particular demonstrated strong antibacterial properties, effectively inhibiting bacterial growth and biofilm formation at low concentrations.

Texas Committee Schedules April 14 Public Hearing on Bill to Expand Access to Medical Cannabis

A House subcommittee has scheduled a public hearing on legislation that would expand Texas’ medical cannabis program.

Colorado Approves First Psilocybin Therapy Center in Downtown Denver

The Center Origin in downtown Denver has become the first facility in Colorado to receive a state license to offer psychedelic therapy under the Natural Medicine Health Act.

Licensed by the Colorado Department of Revenue’s Natural Medicine Division, The Center Origin was officially approved on April 11. Located on Blake Street, the center will provide supervised psilocybin sessions once a licensed testing facility becomes operational to supply the mushrooms.

Colorado began accepting applications for psychedelic healing centers on December 31, 2024. As of Friday, the state has approved one product manufacturer license, four micro-facility licenses, and received 16 additional applications — eight for standard centers and eight for micro-facilities. No testing labs have yet been licensed.

Colorado Lawmakers Introduce Bill to Allow Marijuana Deliveries to Hotels and Expand Event Sales

House Bill 1331 was filed yesterday in Colorado to expand the locations where licensed marijuana businesses can deliver and sell products.

Filed by State Representatives William Lindstedt (D) and Naquetta Ricks (D), the bill has been assigned to the House Business Affairs & Labor Committee.

The proposed law would allow social equity marijuana license holders to deliver marijuana to hotels within the city and county of Denver. To qualify, the licensee must hold a delivery or transporter license for medical or retail marijuana. Deliveries would only be allowed to hotels registered with Denver to receive them, and only if the hotel itself has authorized marijuana delivery and the local jurisdiction has opted into the state’s delivery program. Deliveries would be prohibited to locations that serve alcohol.

Ontario Cannabis Sales Top $150 Million in March

Ontario marijuana retailers generated $150.84 million in sales in March, according to newly released data from Seattle-based research firm Headset.

The total marks a slight 2% decline compared to March 2024. Despite the modest dip, overall marijuana sales in Ontario have reached approximately $450 million for the first three months of 2025, keeping the province on pace for another strong year.

The average cost of dried marijuana flower in March was $9.46 per gram, with an eighth (3.5 grams) selling for around $24. Edibles averaged $4.62 per 10 milligrams of THC, while concentrates were priced at about $32 per gram. Although the average price per gram is up slightly from the average in March 2024, the cost of all other marijuana products have decreased, including a 10% decrease in concentrate and edible prices.
