The largest ever study investigating medical cannabis as a treatment for cancer,published this weekin 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.At-home saliva test for prostate cancer better than blood test, study suggestsRead moreThe study was funded by Cancer Playbook, which works with the Whole House Oncology Institute to collect, analyze and sharedata 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.Castle says his team hoped to find “a moderate consensus” about cannabis’s potential as a cancer treatment, and expected the “best case scenario” to be something like 55% of studies showing that medical cannabis improved cancer outcomes.“It wasn’t 55-45, it was 75-25,” he said.The study overwhelmingly supported cannabis as a treatment for cancer-related inflammation, appetite loss and nausea. Perhaps more surprisingly, it also showed that cannabis has the potential to fight cancer cells themselves, by killing them and stopping their spread.“That’s a shocking degree of consensus in public health research, and certainly more than we were anticipating for a topic as controversial as medical cannabis,” Castle said.Medical cannabis is controversial when it comes to cancer. A 2024 meta-analysis published last year in Jamafound that adults with cannabis-use disorder – defined by criteria including an inability to stop or cut down –were 3.5-5 times more likely to develop head and neck cancer. Donald Abrams, an oncologist and professor emeritus of medicine at the University of California, San Francisco, says that study was “flawed” in his opinion, “as those patients are so often using tobacco and alcohol, known risk factors for those cancers”.For his part, Abrams has found cannabis to be useful for cancer patients managing symptoms like appetite loss, nausea, pain and anxiety. But he is skeptical of claims that cannabis can actuallyfightcancer.“I have been an oncologist in San Francisco for 42 years now where many if not most of my patients have had access to cannabis. If cannabis cures cancer, I have not been able to appreciate that,” he said.Still, Abrams admits that “there is elegant pre-clinical evidence from test tubes and animal models that cannabis can affect cancer cells or transplanted tumors” but “as yet those findings have not translated into clinical benefit in people”.Castle, however, believes that the combination of pre-clinical evidence and patient reported outcomes show that cannabis does have cancer-fighting potential.Asmall pilot trialin which 21 patients received either a placebo or a cannabis-based medication in addition to traditional chemotherapy found that those who received the cannabis-based medication survived for longer. Another study of119 cancer patientsfound that synthetic CBD helped reduce tumor size and tumor cell circulation.But to truly prove the efficacy of cannabis and find the best treatment formulation, there would need to be much larger clinical trials in humans.Castle hopes that his meta-analysis will encourage the US Drug Enforcement Administration to complete the long-stalled process of reclassifying cannabis so it is no longer federally illegal, which could help remove restrictions on clinical research.“We are not arguing that the standards for adopting new cancer treatments should be lower. We are arguing that medical cannabis meets or exceeds those standards,” he said, “often to a greater extent than current pharmaceutical treatments.”

TruthLens AI Summary
The largest-ever study on the use of medical cannabis as a treatment for cancer, recently published in Frontiers in Oncology, has revealed significant scientific support for its potential to alleviate cancer symptoms and potentially combat the disease itself. Led by Ryan Castle, research director at the Whole Health Oncology Institute, this comprehensive analysis aimed to establish a consensus on the efficacy of medical cannabis, an area complicated by the federal classification of marijuana as a Schedule I narcotic. Castle emphasized that the historical challenge in achieving consensus has stemmed from a proliferation of selectively cited studies. The study, funded by Cancer Playbook, analyzed over 10,000 studies related to cannabis and cancer, marking a significant expansion over previous research efforts. Utilizing advanced AI techniques such as sentiment analysis, the team was able to categorize studies based on their findings regarding cannabis's effectiveness in treating cancer symptoms, including inflammation, appetite loss, and nausea, and its potential in directly combating cancer cells.
The findings of the study indicated a striking degree of consensus, with 75% of the studies reviewed supporting the use of medical cannabis for improving cancer-related symptoms and even showing its potential to inhibit cancer cell growth. This level of agreement was unexpected given the controversial nature of cannabis in cancer treatment discussions. Despite some skepticism in the medical community, particularly regarding claims that cannabis can cure cancer, Castle remains optimistic about the implications of the research. He acknowledges the need for further large-scale clinical trials to firmly establish the efficacy of cannabis as a cancer treatment. Castle hopes that this extensive meta-analysis will prompt the U.S. Drug Enforcement Administration to reconsider cannabis's legal status, thereby facilitating more rigorous clinical research. He argues that medical cannabis meets or exceeds the standards for new cancer treatments, often surpassing traditional pharmaceutical options, and calls for a reevaluation of the barriers currently hindering research in this promising area of medicine.
