This naturally has turned some heads, especially since previous research had hinted at the potential for cannabis to prevent the <a href=\"https:\/\/www.veriheal.com\/blog\/new-study-suggests-cannabis-helps-prevent-the-development-of-colon-cancer-in-mice\/\">development of colon cancer<\/a> in mice.<\/p>\n<p>&nbsp;<\/p>\n<p dir=\"ltr\">So what does this new study mean? Here\u2019s what we know about cannabis and colon cancer.<\/p>\n<h2 dir=\"ltr\">The Recent Colon Cancer and Cannabis Study<\/h2>\n<p dir=\"ltr\">The University of California, San Diego School of Medicine <a href=\"https:\/\/www.sciencedirect.com\/science\/article\/pii\/S104727972500078X\" target=\"_blank\" rel=\"noopener\">recently published a study<\/a> in the Annals of Epidemiology titled \u201cCannabis use disorder and mortality among patients with colon cancer.\u201d In the study, researchers indicate that they have found a correlation between high cannabis use and colon cancer mortality.<\/p>\n<p>&nbsp;<\/p>\n<p dir=\"ltr\">The research shows that people with colon cancer and a documented history of heavy cannabis use were more than 20 times more likely to die within five years of their diagnosis than those without a history of heavy use.<\/p>\n<p>&nbsp;<\/p>\n<p dir=\"ltr\">To reach these findings, researchers used electronic health records from more than 1,000 colon cancer patients in the University of California Health system. The records spanned from 2012 to 2024.<\/p>\n<p>&nbsp;<\/p>\n<p dir=\"ltr\">The researchers looked at different cancer outcomes among patients with documented cannabis use before their diagnosis. The study\u2019s controls included age, sex, and indicators of disease severity.<\/p>\n<p>&nbsp;<\/p>\n<p dir=\"ltr\">Here\u2019s what they concluded:<\/p>\n<ul>\n<li dir=\"ltr\">\n<p dir=\"ltr\" role=\"presentation\">Patients with a documented history of <a href=\"https:\/\/www.veriheal.com\/blog\/is-weed-addictive\/\">cannabis use disorder<\/a> (CUD) had a much higher five-year mortality rate than those without CUD: a 55.8% mortality rate vs. 5.05%.<\/p>\n<\/li>\n<li dir=\"ltr\">\n<p dir=\"ltr\" role=\"presentation\">Those diagnosed with CUD before their cancer diagnosis were 24.4 times more likely to die within the first five years of their diagnosis compared to those without CUD.<\/p>\n<\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<p dir=\"ltr\">These figures may be shocking at first glance. But let\u2019s take a closer look at what this study tells us.<\/p>\n<p dir=\"ltr\"><img decoding=\"async\" class=\"alignnone wp-image-39358\" src=\"https:\/\/www.veriheal.com\/blog\/wp-content\/uploads\/2025\/08\/pexels-anntarazevich-8016898-300x200.jpg\" alt=\"Colon Cancer spelt out on a scrabble\" width=\"893\" height=\"595\" srcset=\"https:\/\/www.veriheal.com\/blog\/wp-content\/uploads\/2025\/08\/pexels-anntarazevich-8016898-300x200.jpg 300w, https:\/\/www.veriheal.com\/blog\/wp-content\/uploads\/2025\/08\/pexels-anntarazevich-8016898-1024x683.jpg 1024w, https:\/\/www.veriheal.com\/blog\/wp-content\/uploads\/2025\/08\/pexels-anntarazevich-8016898-768x512.jpg 768w, https:\/\/www.veriheal.com\/blog\/wp-content\/uploads\/2025\/08\/pexels-anntarazevich-8016898-1536x1024.jpg 1536w, https:\/\/www.veriheal.com\/blog\/wp-content\/uploads\/2025\/08\/pexels-anntarazevich-8016898-2048x1365.jpg 2048w\" sizes=\"(max-width: 893px) 100vw, 893px\" \/><\/p>\n<h2 dir=\"ltr\">Important Considerations<\/h2>\n<p dir=\"ltr\">Studies like these can be nerve-racking. But they\u2019re important for us all to have a better understanding of the plant and its risks and benefits. Keep in mind that this study does not paint the whole picture.<\/p>\n<p>&nbsp;<\/p>\n<p dir=\"ltr\">Patients who use cannabis heavily often experience depression, anxiety, and other challenges that can interfere with their full engagement in cancer treatment, according to <a href=\"https:\/\/today.ucsd.edu\/story\/high-cannabis-use-linked-to-increased-mortality-in-colon-cancer-patients\" target=\"_blank\" rel=\"noopener\">lead author Raphael Cuomo, Ph.D<\/a>. \u201cHowever, this isn\u2019t about vilifying cannabis. It\u2019s about understanding the full range of its impacts, especially for people facing serious illnesses. We hope these findings encourage more research \u2014 and more nuanced conversations \u2014 about how cannabis interacts with cancer biology and care,\u201d said Cuomo.<\/p>\n<p>&nbsp;<\/p>\n<p dir=\"ltr\">In one review of the study, gastroenterologist Dr. Veeral Oza said that the study has some flaws. For example, Dr. Oza pointed out that the study was retrospective, meaning it can only point out the connection between cancer and cannabis use\u2014and cannot link one as the cause of the other.<\/p>\n<p>&nbsp;<\/p>\n<p dir=\"ltr\">The study also doesn\u2019t capture disease severity well and is missing over 40% of patient staging criteria. Once the data is adjusted for the limited amount of available severity data they had, the CUD effects are greatly reduced to <a href=\"https:\/\/www.sciencedirect.com\/science\/article\/pii\/S104727972500078X#sec0060:~:text=Unadjusted%20logistic%20regression,0.183\" target=\"_blank\" rel=\"noopener\">between 5 and 7 times<\/a> the odds and are only \u201cmarginally significant\u201d with staging criteria considered. This effect is significant because it shows that many patients with severe disease are just more likely to reach for more cannabis anyway.<\/p>\n<p>&nbsp;<\/p>\n<p dir=\"ltr\">The study also appears to lack any controls for consumption methods. It\u2019s unclear if the analyzed patients were regular smokers or if they were eating edibles or consuming cannabis in harmful ways, like smoking. This is likely the biggest study flaw and undermining feature.<\/p>\n<p>&nbsp;<\/p>\n<p dir=\"ltr\">Smoking is a known contributing risk factor for all cancers, and <a href=\"https:\/\/www.cdc.gov\/cannabis\/health-effects\/cancer.html#:~:text=Is%20there%20a,use%20on%20cancer.\" target=\"_blank\" rel=\"noopener\">burning cannabis can produce similar<\/a> tar, free radicals, and carcinogens. This is an important factor that is entirely missed here, as smoking is still the most common method of cannabis consumption.<\/p>\n<p>&nbsp;<\/p>\n<p dir=\"ltr\">The study also doesn\u2019t appear to go deep into what cannabis use disorder entails, or if habits changed after diagnosis, so it\u2019s unclear just how much cannabis these subjects regularly consumed.<\/p>\n<p dir=\"ltr\" style=\"text-align: center;\"><strong>READ: <a class=\"sc-ciFRQG jVdmlA\" href=\"https:\/\/www.veriheal.com\/blog\/cannabis-for-gut-health-ecs-microbiome-digestion\/\" target=\"_blank\" rel=\"noopener\">Cannabis For Gut Health: How Cannabinoids Can Help with Gut Microbiome, ECS, and Digestive Disorders<\/a><\/strong><\/p>\n<h2 dir=\"ltr\">Cannabis Use Disorder<\/h2>\n<p><img decoding=\"async\" class=\"alignnone wp-image-39130\" src=\"https:\/\/www.veriheal.com\/blog\/wp-content\/uploads\/2025\/07\/pexels-kampus-7928165-300x200.jpg\" alt=\"A lady lighting a cannabis blunt\" width=\"872\" height=\"581\" srcset=\"https:\/\/www.veriheal.com\/blog\/wp-content\/uploads\/2025\/07\/pexels-kampus-7928165-300x200.jpg 300w, https:\/\/www.veriheal.com\/blog\/wp-content\/uploads\/2025\/07\/pexels-kampus-7928165-1024x683.jpg 1024w, https:\/\/www.veriheal.com\/blog\/wp-content\/uploads\/2025\/07\/pexels-kampus-7928165-768x512.jpg 768w, https:\/\/www.veriheal.com\/blog\/wp-content\/uploads\/2025\/07\/pexels-kampus-7928165-1536x1024.jpg 1536w, https:\/\/www.veriheal.com\/blog\/wp-content\/uploads\/2025\/07\/pexels-kampus-7928165-2048x1365.jpg 2048w\" sizes=\"(max-width: 872px) 100vw, 872px\" \/><\/p>\n<p dir=\"ltr\">The recent study points to patients with documented cannabis use disorder. According to the Diagnostic and Statistical Manual of Mental Disorders, DSM\u20135, <a href=\"https:\/\/www.ncbi.nlm.nih.gov\/books\/NBK538131\/\" target=\"_blank\" rel=\"noopener\">cannabis use disorder is defined<\/a> as \u201cthe presence of clinically significant impairment or distress in 12 months, manifested by at least 2 of the following:<\/p>\n<ul>\n<li dir=\"ltr\">\n<p dir=\"ltr\" role=\"presentation\">Cannabis is taken in larger amounts or used over a longer period than intended<\/p>\n<\/li>\n<li dir=\"ltr\">\n<p dir=\"ltr\" role=\"presentation\">Persistent desire to cut down with unsuccessful attempts<\/p>\n<\/li>\n<li dir=\"ltr\">\n<p dir=\"ltr\" role=\"presentation\">Excessive time spent acquiring cannabis, using cannabis, or recovering from its effects<\/p>\n<\/li>\n<li dir=\"ltr\">\n<p dir=\"ltr\" role=\"presentation\">Cravings for cannabis use<\/p>\n<\/li>\n<li dir=\"ltr\">\n<p dir=\"ltr\" role=\"presentation\">Recurrent use resulting in neglect of social obligations<\/p>\n<\/li>\n<li dir=\"ltr\">\n<p dir=\"ltr\" role=\"presentation\">Continued use despite social or interpersonal problems<\/p>\n<\/li>\n<li dir=\"ltr\">\n<p dir=\"ltr\" role=\"presentation\">Important social, occupational, or recreational activities are foregone to be able to use cannabis<\/p>\n<\/li>\n<li dir=\"ltr\">\n<p dir=\"ltr\" role=\"presentation\">Continued use despite physical harm<\/p>\n<\/li>\n<li dir=\"ltr\">\n<p dir=\"ltr\" role=\"presentation\">Continued use despite physical or psychological problems associated with cannabis use<\/p>\n<\/li>\n<li dir=\"ltr\">\n<p dir=\"ltr\" role=\"presentation\">Tolerance<\/p>\n<\/li>\n<li dir=\"ltr\">\n<p dir=\"ltr\" role=\"presentation\">Withdrawal symptoms when not using cannabis\u201d<\/p>\n<\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<p dir=\"ltr\">As evidenced by this list of diagnostic factors, cannabis use disorder is a broad term. It\u2019s not clear which symptoms the patients with documented cannabis use disorder experienced, which makes it difficult to assess the exact role cannabis use plays in colon cancer mortality rates.<\/p>\n<h2 dir=\"ltr\">What We Do and Don\u2019t Know About Cannabis and Colon Cancer<\/h2>\n<p dir=\"ltr\">These types of studies can raise alarms among cannabis users and healthcare professionals. It\u2019s good to be aware of what the recent science indicates, but it\u2019s also important to know that we\u2019re still learning every day, and it\u2019s likely that new research will emerge in the future to provide more context about the relationship between colon cancer and cannabis use \u2013 especially if smoked.<\/p>\n<p>&nbsp;<\/p>\n<p dir=\"ltr\">For now, we know that some cancer patients choose to use cannabis for symptom management related to treatment and the cancer itself. Some patients may turn to <a href=\"https:\/\/www.veriheal.com\/conditions\/nausea\/\">cannabis to improve their nausea<\/a> from chemotherapy or to <a href=\"https:\/\/www.veriheal.com\/conditions\/anxiety\/\">reduce stress and anxiety <\/a>related to their diagnosis, among other reasons. <a href=\"https:\/\/www.veriheal.com\/blog\/how-to-enjoy-the-benefits-of-cannabis-without-smoking\/\">Avoiding cannabis smoking<\/a> in favor of non-inhalational routes is a generally healthy rule of thumb and a great start.<\/p>\n<p>&nbsp;<\/p>\n<p dir=\"ltr\">A previous study showed promise for using cannabis to prevent colon cancer development, though the research was conducted on mice, not humans. Given that more recent science suggests that cannabis use is correlated with higher mortality rates in colon cancer patients, it\u2019s clear that we need more comprehensive studies to gather a clearer picture.<\/p>\n<p>&nbsp;<\/p>\n<p dir=\"ltr\">For now, discuss the findings with your doctor if you are concerned about your cannabis use and its role in other medical conditions. For the prevention of colon cancer, ask your physician when to begin routine screening, pay attention to any unusual symptoms in your body, and follow the <a href=\"https:\/\/www.cdc.gov\/colorectal-cancer\/prevention\/index.html\" target=\"_blank\" rel=\"noopener\">CDC\u2019s recommendations<\/a> for colon cancer prevention. Recommendations include staying active, maintaining a healthy weight, eating a low-animal fat, high fiber (fruits, vegetables, grains) diet, and limiting alcohol and tobacco use.<\/p>\n<p>&nbsp;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Cannabis and cancer have a long and complicated relationship.
