UTHealth Houston Seeks Participants for Study on Psilocybin (“Magic Mushrooms”) for Depression

UTHealth Houston is currently recruiting participants for a study exploring the potential of psilocybin, a compound found in “magic mushrooms,” to treat individuals with treatment-resistant depression.

The study, conducted by the Center of Excellence on Mood Disorders, is part of a global multi-center initiative sponsored by COMPASS Pathways. The trial will involve a single administration of either 25 mg of psilocybin or a placebo. Participants will be closely monitored and supported by specially trained therapists throughout the process. These therapists will guide them before, during, and after the psilocybin session to ensure a safe and comfortable experience.

A key requirement for participation is that all individuals on antidepressants must taper off their medication 3 to 6 weeks before the study’s baseline phase. The study team will assist with this tapering process to ensure patient safety.

Federal Appeals Court Rules THC-O Is Federally Legal, Rejecting DEA’s Stance

The U.S. Court of Appeals for the Fourth Circuit has ruled that the hemp derivative THC-O-acetate is federally legal under the 2018 Farm Bill.

In giving their ruling, the appeals court rejected the Drug Enforcement Administration’s (DEA) position that it should be classified as a Schedule I controlled substance, making it illegal nationwide for all purposes.

The ruling, issued yesterday, stemmed from an employment dispute where the legality of THC-O was a key issue. The majority opinion from a three-judge panel determined that the DEA’s interpretation of the law was overly broad and did not apply to THC-O, which can be synthesized from cannabinoids found in legally cultivated hemp. In its decision, the Fourth Circuit referenced a prior ruling from the Ninth Circuit, which held that the 2018 Farm Bill legalized a broad range of hemp-derived cannabinoids, including delta-8 THC.

Ohio Approves 121 More Licenses for Marijuana Stores, Places Cap in the Largest Cities

Ohio’s Division of Cannabis Control (DCC) has nearly doubled the number of approved applications for marijuana retail licenses, while simultaneously capping the number of cannabis retail outlets in the state’s three largest cities.

While approving 121 new store applications, the DCC ruled that 47 of these retailers cannot open in Franklin, Cuyahoga, or Hamilton counties, which encompass Columbus, Cleveland, and Cincinnati. The DCC determined that these areas already have adequate retail presence, and no new licenses will be approved for the foreseeable future.

The newly approved permits are part of the state’s “10(B) license” program, which allows licensed growers and retailers to expand operations. The approvals come in addition to the 123 medical marijuana dispensaries that began selling adult-use products on Aug. 6.

Study: THC and CBD Combo May Slow Alzheimer’s Progression by Modulating Brain Chemistry

A groundbreaking study published in the per reviewed journal Neurotherapeutics shows that a combination of tetrahydrocannabinol (THC) and cannabidiol (CBD) may offer new hope for treating Alzheimer’s disease (AD).

“A combination of Δ9-tetrahydrocannabinol (Δ9-THC) and cannabidiol (CBD) at non-psychoactive doses was previously demonstrated to reduce cognitive decline in APP/PS1 mice, an animal model of Alzheimer’s disease (AD)”, starts the study’s abstract. “However, the neurobiological substrates underlying these therapeutic properties of Δ9-THC and CBD are not fully understood.”

Considering that dysregulation of glutamatergic activity contributes to cognitive impairment in AD, the present study “evaluates the hypothesis that the combination of these two natural cannabinoids might reverse the alterations in glutamate dynamics within the hippocampus of this animal model of AD.”

Study: CBD Extends Lifespan and Reverses Symptoms in Mitochondrial Disease

A new study published in the journal Nature Communications reveals that cannabidiol (CBD) may offer a breakthrough in treating primary mitochondrial diseases (MD), a group of untreatable disorders caused by mutations in energy-producing genes.

The research specifically focuses on Leigh syndrome (LS), the most common pediatric MD, which is marked by progressive neuromuscular impairment and early death.

The study shows that daily CBD administration significantly extends lifespan and improves various symptoms in two mouse models of Leigh syndrome.

New Hampshire Legislature to Hold Hearing on Marijuana Legalization Next Week

In exactly one week, on September 12, a New Hampshire legislative committee will hold a public hearing on the legalization of marijuana.

Specifically, the public hearing will be on House Bill 544, which is set for a “full committee work session” on September 12 at 10:00 a.m. in the Legislative Office Building, Rooms 302-304. House Bill 544, filed in January 2023 by five Democrats, would legalize marijuana in a manner similar to alcohol, including a putting control of the legal marijuana market in the hands of the state liquor commission.

According to recent polling, 65% of New Hampshire residents are in favor of legalizing marijuana for everyone 21 and older, indicating strong public backing.

California Senate Bill 1064, introduced by Senator John Laird (D) in April, has passed both the full Assembly (73 to 0) and Senate (37 to 1). Yesterday, the measure was presented to Governor Gavin Newsom, giving him 12 days to decide whether to sign it into law, allow it to become law without a signature, or veto it.

SB 1064 introduces a new “combined activities license,” which would allow two or more cannabis-related business activities to operate under a single license at the same premises, with the exception of laboratory testing. Under current law, cannabis operators are required to apply for separate licenses for each activity they wish to conduct, such as retail sale, cultivation, and distribution. This bill seeks to simplify the licensing process by allowing certain activities to be combined, reducing the administrative burden on businesses.

Idaho Nonprofit Announces Forthcoming Initiative to Decriminalize Marijuana Possession and Cultivation

The nonprofit political group Kind Idaho has announced that they will soon unveil an initiative to decriminalize marijuana, with the goal of putting it to a vote of the people in 2025 or 2026.

“Our 2023-2024 campaign has concluded and we did not meet the requirements to get on the ballot”, said Kind Idaho in a social media post. The group was referring to a medical marijuana initiative they were hoping to place on this year’s ballot, but fell short of the required signatures. “Thank you to everyone that signed, donated, volunteered!”

The group says “We will be restructuring and rebranding soon to be focused on patient advocacy in general and our next ballot initiative will be aimed at cannabis decriminalization. More information to follow.”

Study Finds CBD May Enhance Cancer Immunotherapy in Triple-Negative Breast Cancer

A study published in the recent issue of the journal  Cancer Immunology Research suggests that cannabidiol (CBD) may enhance the effectiveness of atezolizumab, a drug commonly used in treating triple-negative breast cancer (TNBC).

The study, which was published online ahead of print by the National Library of Medicine, highlights the potential for CBD to be used as an immune modulator, offering a new avenue for improving cancer treatments.

Triple-negative breast cancer is an aggressive form of cancer that often relies on cytotoxic therapies. Current treatments include the combination of atezolizumab, an immune checkpoint inhibitor (ICI), with chemotherapy. However, the effectiveness of this combination is limited for patients with low reactivity to atezolizumab, prompting researchers to explore alternative treatments that could enhance its efficacy.
