Marijuana and Constipation: Does Cannabis Affect Your Digestive System?

The answer isn’t as simple as yes or no.

Marijuana has found a place in our society in large part as a natural tool that can help people with a wide range of medical problems. While children with severe seizures and cancer patients are often attached to medical marijuana stories, not all of marijuana’s medical benefits apply to only serious problems. In fact, for thousands of years, people have believed there is a healing link between marijuana and constipation, including the Chinese in 2700 BCE.

Cannabis has been used as a treatment for many digestive related illnesses such as Crohn’s Disease and the side effects of Chemotherapy, and while the science on cannabis’ laxative effects is limited, studies seem to indicate that cannabis use, THC to be more specific, may help combat the symptoms of inflammatory bowel disease and help reduce diarrhea.

Marijuana and Constipation

However, much like anything else, too much can cause the opposite of the desired effect, although to understand exactly how THC plays into your bathroom schedule requires more research. The same goes for CBD.

There is evidence that shows CBD, among other cannabinoids, does affect gastric motility – which determines how quickly or slowly matter passes through the intestines. How cannabis affects you is dictated in large part by which cannabinoids you’re consuming. Given the fact that there are over 70 known cannabinoids until cannabis is legalized and we can research each cannabinoid more in-depth, any answer that you receive regarding cannabis and constipation is going to come with an asterisk.

Medical marijuana can often be a huge help in many problems that arise from the standard opiate protocol that many doctors prescribe (like constipation.) Not only do patients feel like they have more control, but they also are less likely to become addicted to opiates and subsequently not have to face harsher side effects from opiates.

The science on everything marijuana-related is limited, but according to this self-reported data, long term cannabis users often experience constipation as one of the symptoms that can develop with cannabis use. This study does have its flaws though. In general, there is nothing wrong with self-reported data. However, it mentions that many of the individuals who reported constipation with marijuana also have irritable bowel syndrome. Since constipation can be a side effect of IBS, these results should be taken with a grain of salt.

Claims That Cannabis Help With Constipation Are Not Based In Science

There are websites that will claim that cannabis can actually help with constipation. says that “Research reveals medical marijuana can treat digestive disorders, including constipation. Constipation can also be caused by digestive disorders treated with medical marijuana.”

However, the one thing noticeably missing from the entire article is the actual research that supports that claim. They aren’t the only culprits, either. If you search “marijuana constipation” on Google, the entire first page of search results is full of “experts” coming to baseless conclusions about the benefits of cannabis when it comes to constipation. This is a prime example of misinformation poisoning the cannabis dialogue and setting back any efforts to legitimize the plant and the industry. The real answer is there isn’t enough research right now to definitively make the claim that cannabis helps OR hurts your constipation.

Marijuana use has long been considered a tool to help constipation, but much of that evidence is largely anecdotal without any actual scientific evidence. While that may be the norm for answering any health-based questions related to cannabis, it can cause real-world problems for people who then have to blindly test if the claims are solid.

What To Do If You’re Constipated

A problem that people can run into is the fact that constipation can’t actually be cured by marijuana, meaning that if you really want to fix the problem you may have to try some stool softeners or make some lifestyle changes.

Any serious constipation problems that you have may be from underlying health issues instead of THC, but the relationship between our bowel movements and our smoking habits is real and something that you should monitor. If you run into any small problems with your bowels and suspect that it may have something to do with your cannabis consumption, some of the quick fixes that you could try out include switching the strains, looking at your diet, or taking a break from weed. If you have constipation, but no alarming symptoms, try journaling everything you ingest (food and cannabis) for a week or two to see if you can figure something out yourself.

If you have serious concerns, you’ll definitely want to consult your doctor, especially if you exhibit any of these symptoms:

  • Severe abdominal pain
  • Vomiting
  • Fevers
  • Inability To Pass Gas
  • Severe Rectal Pain

CBD and Diarrhea

CBD has been said to cause diarrhea, which can cause way more problems in the short-term if not dealt with.

Diarrhea comes from a number of different reasons and illnesses that our body can cook up, with the bathroom nuisance often being a side-effect of another problem. However, diarrhea is often the cause of dehydration.

CBD related problems often occur from the act of overdoing it, as smaller doses and non-daily use will not likely cause many health issues for you. However, as with THC and constipation, the relationship between CBD and its side-effects are understudied, to say the least.

There are potentially other reasons you are suffering from diarrhea, including:

  • Infections
  • Food allergies and intolerances
  • Digestive tract problems
  • Certain medicines, like antibiotics

If you are dealing with some nasty side-effects and think CBD is to blame, try changing your dose, the strain or the method you use to take it. Going from oil to topical treatment may be all you need to stop unwanted effects, plus it is never a bad thing to try new things.

You should consult your doctor about your diarrhea if you have any of the following symptoms:

  • Diarrhea for more than 2 days
  • Fever
  • Vomiting
  • 6 or more loose stools in 24 hours
  • Severe pain in the abdomen or rectum
  • Diarrhea that is bloody or resembles coffee grounds

Where Do We Go From Here?

There is a common theme when it comes to answering questions about how cannabis interacts with the body: more research is needed. Until cannabis is federally legal and the appropriate studies can take place, we won’t know definitively all the ways in which cannabis affects your body and why.

Marijuana and constipation are often talked about together, but there isn't enough research to conclude if marijuana helps or hurts your cause.

    If you’re struggling with consistent healthy bowel movements, you might try smoking marijuana. According to new research published in The American Journal of Gastroenterology, those who recently smoked weed were less likely to suffer from constipation.

    Scientists still don’t completely understand how cannabis affects the gastrointestinal system and digestive process. To better understand the relationship, researchers identified American adults who completed the drug use and bowel movement questionnaires in the National Health and Nutrition Examination Survey over a 6-year period from 2005 to 2010. Using the Bristol Stool Form Scale, scientists then analyzed the likelihood of an individual suffering from chronic constipation or diarrhea based on recent marijuana use.

    According to the study, recent weed consumption was associated with 30% lower odds of constipation. The prevalence of constipation was also lower for those who reported recently consuming marijuana when compared to those who had never used or done so in the past. These results persisted when the scientists adjusted for demographic factors like race, sex, and socioeconomic status.

    However, there was no relationship with recent toking and diarrhea symptoms.

    “Our analysis is the first population-based human clinical study of marijuana and bowel function providing important insights into the aggregate effects of the various components of the marijuana plant on constipation,” the study’s authors wrote. “Owing to the high prevalence and burden of constipation in combination with the increasing availability of both recreational and medicinal cannabis, further studies are needed to identify how use of whole cannabis, different marijuana strains, and frequency of marijuana use exert their apparent effects on constipation.”

    Previous research on marijuana’s effect on the gastrointestinal system has been conflicted. While the authors demonstrated an association between recreational marijuana use and constipation, other studies have provided different results.

    “Current evidence suggests that cannabinoids slow colonic transit through actions on the CB1 receptor,” the researchers wrote. “However, a recent clinical trial reported that hemp seed pills improved constipation symptoms among patients with functional constipation, suggesting that the summative effect of the separate cannabinoids in the marijuana plant might have a unique effect on bowel motility.”, a U.S. lifestyle site, that contributes lifestyle content and, with their partnership with 600,000 physicians via Skipta, medical marijuana information to The GrowthOp.
