A new study says Joe Rogan’s podcast helped drive a nationwide spike in off-label cancer drug prescriptions, and the medical establishment is using it to tighten its grip on who gets to talk about health.
Story Snapshot
- Prescriptions for ivermectin and related dewormers more than doubled after Mel Gibson described “cancer cures” on Joe Rogan’s show.
- Researchers say there are zero human cancer trials proving the drug combo works, warning patients may skip proven treatments.
- The same experts admit the study cannot prove Rogan caused the spike and only tracked doctor orders, not actual use.
- The fight over this study is really about free speech, medical gatekeeping, and who conservatives can trust on life-and-death health choices.
What The New Ivermectin Study Actually Found After Rogan’s Podcast
Researchers from a large national network of health systems reviewed electronic records for more than sixty-eight million American patients to track prescriptions for ivermectin and benzimidazole drugs before and after actor Mel Gibson’s appearance on “The Joe Rogan Experience” on January 9, 2025.[1][4] On that episode, Gibson claimed three friends with stage four cancer recovered after taking ivermectin and fenbendazole, a dewormer normally reserved for animals.[1][2][3] Clips quickly flooded social media platforms.[2]
The peer-reviewed study in JAMA Network Open reported that overall ivermectin prescriptions roughly doubled in the six months after the podcast compared with the same period a year earlier.[1][2][4] Among people with cancer, prescribing of the ivermectin–benzimidazole combination rose more than two and a half times, with the biggest jumps among men, white patients, and Americans living in the South.[1][2][3] In the South, rates reportedly more than tripled year over year, showing how strongly the message resonated regionally.[2][3]
Doctors Call The Drugs “Unproven” While Admitting Serious Gaps In The Data
The same researchers are clear on one major point: there have been no clinical trials in humans proving that the ivermectin–benzimidazole regimen is safe or effective as a cancer treatment.[2][3][4] They note some laboratory and animal studies suggest the drugs can attack cancer cells, but the doses needed to show even small anticancer activity in those settings would be toxic for people, according to oncologist Skyler Johnson of the University of Utah.[3] HealthDay’s report echoes that no human cancer trials have yet validated real-world benefit.[2]
Despite that firm language, the study’s authors quietly admit their work has limits that matter for policy and free speech.[1][2][4] The design is observational, which means they cannot prove Rogan’s show caused the prescribing surge, only that the spike followed his guest appearance.[2][4] They also examined physician orders, not whether patients filled prescriptions, took the drugs, or stopped standard chemotherapy or radiation. The authors concede their sample might not perfectly represent the entire United States population.[2][4]
Medical Gatekeepers Use The Spike To Push Censorship, Not Transparency
Public health commentators are using the results to sound an alarm about “misinformation,” warning that celebrity endorsements can push desperate patients to delay or abandon therapies that have been proven to save lives.[1][2][3] One UCLA physician said that when prescriptions for an unproven regimen more than double after a single podcast, especially among men in the South, it raises concern that patients could be skipping or delaying effective treatments for something that has not been shown to help.[2][3] These experts are already calling for new strategies to counter such messages at “the point of care.”[2]
What those strategies look like is not spelled out in the research, but recent history offers clues. During the pandemic, health bureaucracies leaned on social media companies to throttle, label, or remove content that conflicted with official narratives, including discussions of off-label drugs like ivermectin.[3] The new study’s framing fits neatly into that pattern, portraying podcast conversations as a public health problem rather than a free exchange of ideas among adults. That worries conservatives who watched unelected officials blur the line between medical advice and government-enforced speech controls.
Balancing Medical Caution With Patient Freedom And Personal Responsibility
For many readers who lived through the pandemic, the ivermectin debate feels familiar. On one hand, the scientific record on cancer is straightforward: regulators have approved ivermectin for parasitic infections, not tumors, and there are currently no human cancer trials proving that ivermectin or fenbendazole can safely cure malignancies.[2][3] On the other hand, researchers themselves acknowledge that these drugs have shown anti-cancer activity in laboratory and animal models, which explains why some patients are curious and some doctors are willing to experiment within legal off-label practice.[2]
More cancer patients are using unproven ivermectin and Joe Rogan podcast may be why https://t.co/FrBXaRUmJB

The real question for a free society is not whether people should blindly swallow every claim they hear online. They should not. The question is who gets to decide what they are allowed to hear in the first place. Millions of Americans distrust pharmaceutical giants and federal health agencies after years of shifting guidance and politicized science. They want to hear unfiltered stories, then discuss options with doctors they trust. That is how informed consent is supposed to work in a constitutional republic.
