Medical cannabis shows potential to fight cancer, largest-ever study finds

The largest ever study investigating medical cannabis as a treatment for cancer, published this week in Frontiers in Oncology, found overwhelming scientific support for cannabis’s potential to treat cancer symptoms and potentially fight the course of the disease itself.

The intention of the analysis was to solidify agreement on cannabis’s potential as a cancer treatment, said Ryan Castle, research director at the Whole Health Oncology Institute and lead author of the study. Castle noted that it has been historically difficult to do so because marijuana is still federally considered an illegal Schedule I narcotic.

“Our goal was to determine the scientific consensus on the topic of medical cannabis, a field that has long been dominated by a war between cherrypicked studies,” Castle said.

The study was funded by Cancer Playbook, which works with the Whole House Oncology Institute to collect, analyze and share data on patient-reported outcomes.

While research restrictions on Schedule I substances severely hamper clinical research on cannabis in humans, there is a large body of observational studies on medical cannabis and cancer – as well as lab research – that looks at cannabis’s effect on tumors in test tubes and in animals. The analysis included as many of those studies as possible.

“In order to move beyond bias – conscious or not – it was essential to use a large-scale, radically inclusive methodology based on mathematical reasoning,” Castle said, adding: “We wanted to analyze not just a handful, but nearly every major medical cannabis study to find the actual points of scientific agreement.”

Castle’s study looked at more than 10,000 studies on cannabis and cancer, which he said is “10 times the sample size of the next largest study, which we believe helps make it a more conclusive review of the scientific consensus”.

To analyze the massive quantity of studies, Castle and his team used AI – specifically, the natural language processing technique known as “sentiment analysis”. This technique allowed the researchers to see how many studies had positive, neutral or negative views on cannabis’s ability to treat cancer and its symptoms by, for example, increasing appetite, decreasing inflammation or accelerating “apoptosis”, or the death of cancer cells.

Drug Enforcement Leads To Increases In Violence, Report Published By UK Government Concludes

Drug-related law enforcement is more likely to increase violence than reduce it, indicates a report commissioned by the government of the United Kingdom. Whether the government will revise its drug policies accordingly remains to be seen.

“The available evidence suggests that drug-related law enforcement activities are of limited effectiveness in reducing violence,” states the report, which was prepared by the research organization RAND Europe and published by the UK Home Office on March 27. “Indeed, more studies demonstrated an association between drug-related law enforcement activities and increased violence than decreased violence.”

The findings, which echo earlier evidence on the subject, are less startling than the fact that the UK government published them. The report references a prior review on the impact of drug-related law enforcement activity on serious violence and homicide, which, it notes, “found that increasing drug law enforcement was unlikely to reduce drug market violence alone and risked exacerbating it.”

The report urges British police forces planning drug-related law enforcement actions to “consider the risk of increased violence,” particularly related to the removal of leaders of trafficking groups and drug seizures.

“The counterproductive nature of drug law enforcement has been very obvious for a long time,” Steve Rolles, senior policy analyst at the Transform Drug Policy Foundation, told Filter. “The war on drugs has fueled an arms race between law enforcement agencies and organized crime groups—ensuring only the most cunning and  violent crime groups prosper.”

Nonetheless, he continued, “It is welcome to see the systemic failure of the enforcement model confirmed by academic work commissioned and published by the Home Office itself. It certainly makes it a lot harder for them to ignore.”

The Home Office, which is responsible for areas including public safety, policing and border security in the UK, did not respond to Filter’s request for comment on whether it would act on the report’s recommendations.

Former police officers are among those who have long warned that the disruption of drug markets increases violence, as trafficking groups fight over resultant power vacuums when established hierarchies are disturbed by seizures and arrests.

“For years I’ve been arguing that no police activity in drug markets reduces the size of the market,” Neil Woods told Filter. A former undercover police officer, he changed his mind about the drug enforcement actions he once participated in. He now chairs the Law Enforcement Action Partnership UK, which campaigns to end the drug war.

“This kind of study should not just be of niche interest, it should inform policy,” he said. “We are talking about the very fabric of security and safety in our society.”

Police disruption of drug markets also increases the risk of overdose among people who use drugs, Woods added, citing a 2023 study, published in the American Journal of Public Health, which illustrated this. In what has been described as “the drug bust paradox,” the arrest of a person’s source of drugs can lead them to experience withdrawal and hastily seek a new source—who might provide drugs that are adulterated or of higher potency.

A trip too far: The LSD experience that blew up the Huxley family

In November 1956, three people gathered in a converted Connecticut barn to take LSD, a powerful psychedelic drug that was legal at the time. 

The children had just been put to bed upstairs. In the converted barn’s main room, Elizabethan ballads drifted through smoke-thick air as someone scattered chrysanthemum petals across a sheepskin rug. The flowers seemed to reanimate in the candlelight, blooming and dying with each flicker. Two of the participants lay hand-in-hand in ecstatic communion, while a third sat rigid and apart, his detachment crumbling into barely contained fury. 

By midnight, everything would shatter. 

One participant spiraled into visions of nuclear war. Another transformed into a 10-foot colossus of feminine power. And in the space between these extremes, a marriage began its quiet collapse. 

The aftershocks would reverberate through three generations of Britain’s most celebrated intellectual family, the Huxleys, leaving wounds that simmered in private letters for more than sixty years. 

It’s fitting that this story should be told on Bicycle Day, the annual commemoration of April 19, 1943, when Swiss chemist Albert Hofmann first rode his bike home under the effects of LSD — and ushered in the modern psychedelic era. Nearly 14 years after that inaugural ride, the drug had drifted from the lab into the lives of artists, seekers and intellectual elites like the Huxleys. 

The trip’s architect was Dr. Humphry Osmond, the psychiatrist who had first guided Aldous Huxley — the author of “Brave New World” and “The Doors of Perception” — in experiments with mescaline. and coined the term “psychedelic.” His subjects that evening were Aldous’ only son, Matthew Huxley; Matthew’s wife, Ellen; and Francis Huxley, Matthew’s cousin and the son of biologist Julian Huxley.

Former Marijuana Prisoners Who Got Clemency From Trump Hold Event Outside White House To Request Relief For Those Still Behind Bars

Former marijuana prisoners who received clemency from President Donald Trump during his first term staged an event outside the White House on Thursday, expressing gratitude for the relief they were given and calling on the new administration to grant the same kind of help to others who are still behind bars for cannabis.

Flanked by cardboard cutouts of individuals pardoned or granted commutations by Trump, activists impacted by criminalization stood outside the White House with a message to “free all cannabis prisoners.”

The grassroots “Cannabis Prisoners Unity Day” called attention to the opportunity to build upon the executive-level relief. In addition to Trump’s clemency actions in his first term, former President Joe Biden also pardoned and commuted sentences for hundreds of people while he was in office. But numerous people remain behind bars over non-violent federal cannabis convictions.

“President Trump, we are your example of a victory,” Craig Cesal—who received a commutation for a life sentence he was handed down in 2002 for a marijuana distribution conviction—said during a panel discussion ahead of the White House meetup.

For 4/20, Ben & Jerry’s Teams Up With Marijuana Justice Group To Push Governors To Free Cannabis Prisoners

As consumers and businesses across the U.S. gear up for the 4/20 holiday on Sunday, ice cream maker Ben & Jerry’s is drawing attention to the “tens of thousands of people who will spend their 4/20 in prison for the same cannabis-related activity.”

This year the company—which has regularly used 4/20 to highlight justice-related cannabis matters—has partnered with the advocacy group Last Prisoner Project (LPP) to urge state governors to grant relief to those behind bars for marijuana.

“This 4/20, the need for cannabis justice is at an all-time HIGH,” Ben & Jerry’s said about the new effort.

The groups are also encouraging supporters to take action, recommending they reach out to their state governors to call for clemency, sign petitions to free people incarcerated for cannabis crimes, spread the word using the #420ForFreedom on social media and attend a Washington, D.C. event—the Cannabis Unity Week of Action, held April 29 through May 1—aimed at promoting broader marijuana legalization.

The company says that as “cannabis businesses will rack up sales, public figures will use their platforms to highlight cannabis culture, and millions of Americans will take advantage of their freedom and consume with friends and family” on 4/20, it’s crucial that advocates continue pushing to right the wrongs of prohibition.

“When we say legalization without justice is half baked, we mean that legalization while people, disproportionately Black and Brown, are still sitting in prison for cannabis or reeling from the detrimental impacts of having a cannabis conviction on their records is simply not justice fully realized,” Palika Makam, Ben & Jerry’s U.S. activism manager, said in a statement.

North Carolina Lawmakers File Bill To Legalize Medical Marijuana For Patients With Debilitating Conditions

A new bill in the North Carolina House of Representatives would legalize medical marijuana for patients with a variety of specified conditions, including cancer, epilepsy, HIV/AIDS, Parkinson’s disease, PTSD, end-of-life care and other serious ailments.

The measure, HB 1011, was filed on Tuesday by Rep. Aisha Dew (D) and has been cosponsored by several other Democratic lawmakers.

The 28-page bill, titled the North Carolina Compassionate Care Act, is considerably more detailed than a separate Democrat-led medical marijuana bill introduced this week that would allow access only for patients enrolled in a “registered research study.”

Advocates have been awaiting House introduction of a comprehensive bill, especially since Senate President Phil Berger (R) said his chamber is deferring to the House to move first on medical marijuana reform this session.

“Glad to finally see a real medical cannabis bill get introduced,” Kevin Caldwell, Southeast legislative manager for the advocacy group Marijuana Policy Project, told Marijuana Moment in an email Wednesday.

The new bill, HB 1011, appears to be based largely on an earlier medical marijuana proposal from Sen. Bill Rabon (R), SB 3, filed in the 2023–2024 legislative session. That measure passed the Senate but failed to advance in the House due to an informal rule that requires a majority of the chamber’s GOP caucus to support a bill in order to bring it to the floor.

Caldwell at MPP said he would have liked to see the new House medical marijuana bill be sponsored by a Republican, which he reasoned would increase its chances of being heard in the GOP-controlled body. But he added that “legislators have known a medical bill has been in the works, and I hope they take this opportunity to provide relief to the tens of thousands of North Carolinians who are suffering from debilitating conditions.”

The new measure says in its findings section that “medical research has found that cannabis and cannabinoid compounds are effective at alleviating pain, nausea, and other symptoms associated with several debilitating medical conditions.” A majority of states and four of five U.S. territories have already legalized medical marijuana, it continues, and “North Carolina now takes similar action to preserve and enhance the health and welfare of its citizens.”

Under the proposal, the new medical cannabis program would be overseen by the state Department of Health and Human Services (DHHS).

Arkansas GOP Governor Vetoes Bill To Allow Drive-Thru Medical Marijuana Sales At Dispensaries And Ease Delivery Rules

The Republican governor of Arkansas has vetoed a bill that would have allowed medical cannabis sales at drive-thru windows at dispensaries, while also easing certain rules around marijuana delivery services for patients and caregivers.

After the legislation from Rep. Aaron Pilkington (R) narrowly advanced through the legislature, Gov. Sarah Huckabee Sanders (R) returned the measure with a veto message on Wednesday.

“This legislation would expand access to usable marijuana, therefore I am vetoing this legislation,” Sanders said.

Under the bill, licensed dispensaries would be have been authorized to “deliver usable marijuana to a qualified patient or designated caregiver via a drive-through window located at the dispensary,” the text says.

People would have needed to place an online order and pick up their products on the same day of the transaction.

The measure also would have revised existing statute to allow visitors to tour dispensaries in additional to cultivation facilities. And it would have made it so conventional medical cannabis deliveries could be handled by one employee, instead of the current minimum of two, if additional security measures were taken.

The governor didn’t address any of the specifics of the bill, instead simply voicing opposition to the idea of expanding access to cannabis.

Florida House Committee Approves Hemp Regulatory Bill That Would Impose 15% Tax On All THC Products

All hemp-derived THC products would be taxed at 15 percent under a proposal passed in a Florida House committee on Wednesday.

The measure is one of two regarding regulation of hemp-derived THC products sponsored by Panhandle Republican Rep. Michelle Salzman that were approved unanimously in the House Budget Committee.

The main bill (HB 7027) is a companion to a Senate bill (SB 438) that has already passed unanimously in that chamber, although they do contain significant differences. Among them is that Salzman’s bill would not ban delta-8, the hemp-derived THC product that has grown in popularity since hemp was legalized in the United States through the 2018 U.S. Farm Bill.

Like its Senate companion, the House bill limits the amount of delta-9 THC in hemp-derived products such as beverages and gummies. It says edibles must contain no more than 2 milligrams, be individually wrapped and be sold in containers with no more than 20 edibles.

That raised objections from Patrick Shatzer of Sunmed/Your CBD Store, who says his company is the largest CBD brick-and-mortar business in the country, with 260 locations nationwide and 42 in Florida.

“The size of the gummies—limited to 2 grams—that’s just a tiny little pinkie size wide,” he said to the committee. “That’s not the industry standard. The industry standard is anywhere from 5 to 8 grams.”

Shatzer also objected to the provision limiting 20 servings per container, saying the average dietary supplements permit 30 gummies in a container. And he raised objections to a prohibition on selling, delivering, bartering, giving or furnishing hemp consumables that total more than 100 milligrams of THC to a person in a 24-hour period, saying it would be unenforceable.

Rep. Salzman replied that, while she is open to changing some of those limits, she is holding firm on limiting personal consumption of such products to 100 milligrams of THC a day.

“If somebody knows that they can’t buy more than 100 milligrams in that day, it’s going to give them a warning subconsciously, ‘Maybe I shouldn’t have more than 100 milligrams of this stuff in a day,’” she said. “And if you want more than 100 milligrams of this stuff a day, you probably need to get a medical cannabis card.”

Regarding the proposed 15 percent excise tax on hemp products, Jodi James of the Florida Cannabis Action Network said that not all hemp products are intoxicating, and that those that aren’t should not be taxed at all.

“In the state of Florida, we don’t tax vitamins, we don’t tax supplements,” she said.

Florida Senate Passes Bill To Ban Psychedelic Mushroom Spores, As Companion Measure Also Advances In House

Florida’s Senate on Wednesday passed a wide-ranging agricultural bill that contains provisions to outlaw fungal spores that produce mushrooms containing psilocybin or psilocin. The vote came a day after a House committee advanced a companion bill in that chamber.

Senators voted 27–9 to approve SB 700, from Sen. Keith Truenow (R). HB 651 is moving through the House, meanwhile, having advanced out of the Commerce Committee on Tuesday.

The proposed ban on spores of mushrooms that create psilocybin or psilocin is a small part of the roughly 150-page legislation, which would make a variety of adjustments to Florida’s agricultural laws, including around agricultural lands, utilities and wildlife management.

With respect to psychedelic mushrooms, both measures would outlaw transporting, importing, selling or giving away “spores or mycelium capable of producing mushrooms or other material which will contain a controlled substance, including psilocybin or psilocyn, during its lifecycle.”

Violating the proposed law would be a first-degree misdemeanor, carrying a maximum one year in jail and $1,000 fine.

While lawmakers on the Senate floor and House committee spent considerable time debating various other portions of the bills—especially a proposed ban on fluoride in local water supplies—there was no mention of the provision concerning psychedelic mushroom spores.

“This bill at its core is meant to help farmers and consumers and students who want to become farmers one day,” Truenow said ahead of the floor vote.

Psilocybin and psilocin are the two main psychoactive compounds in psychedelic mushrooms. Although spores themselves typically do not contain psilocybin or psilocin, they eventually produce fruiting bodies—mushrooms—that do contain the psychedelic compounds.

Because the spores don’t contain any controlled substances, the federal government deems them legal.
