New Study Shows Marijuana Helps To Relieve Crohns Disease Symptoms

Cannabis use is associated with a reduction in Crohn’s disease (CD) activity and disease-related surgeries, according to the results of a retrospective observational study published in the August issue of the Journal of the Israeli Medical Association.

Investigators at the Meir Medical Center, Institute of Gastroenterology and Hepatology assessed ‘disease activity, use of medication, need for surgery, and hospitalization’ before and after cannabis use in 30 patients with CD.

Authors reported, “All patients stated that consuming cannabis had a positive effect on their disease activity” and documented “significant improvement” in 21 subjects.

Specifically, researchers found that subjects who consumed cannabis “significantly reduced” their need for other medications. Participants in the trial also reported requiring fewer surgeries following their use of cannabis.

“Fifteen of the patients had 19 surgeries during an average period of nine years before cannabis use, but only two required surgery during an average period of three years of cannabis use,” authors reported.

They concluded: “The results indicate that cannabis may have a positive effect on disease activity, as reflected by a reduction in disease activity index and in the need for other drugs and surgery. Prospective placebo-controlled studies are warranted to fully evaluate the efficacy and side effects of cannabis in CD.”

Researchers at the Meir Medical Center are presently evaluating the safety and efficacy of inhaled cannabis for patients with CD and Ulcerative Colitis in a double-blind, placebo-controlled trial.

Crohn’s disease and Ulcerative Colitis are inflammatory bowel diseases. According to survey data published earlier this year in the European Journal of Gastroenterology and Hepatology, an estimated one-third of patients with colitis and one-half of subjects with CD acknowledge having used cannabis to mitigate their disease symptoms.

About Author


  1. I have suffered with CD for over 20 years, I am allergic to most medications used in treating symptoms of & for Crohns Disease. I’ve had over 70 surgeries & now suffer from other Crohns related illnesses. I live in South Australia, where medicinal marijuana is illegal & looks to always be. Therefore I have to acquire marijuana illegally, which is both expensive & very stressful (which adds to my illness). The Australian Government needs to seriously look into doing the same as some American States & countries are doing with marijuana to help stop sick, suffering & dying individuals from suffering any longer.

  2. Crohnns may be incurable using drugs, however doing a bowel cleanse with a quality herbal product this condition can be corrected. Proper diet and a will to survive is also ecental.

  3. Dont worry about it on

    I have UC and it helps a lot more than I thought it would. I always scoffed at the new age type of people that claimed pot would fix anything and everything, and while I still do scoff, I scoff a lot less. Its almost miracle-like the relief I get from smoking. I can be in agonizing pain one second and a few puffs later it is magically gone, I know its not a cure but it helps me live without being in constant fear and pain, plus it gets you high if youre into that.

  4. True story. I myself have CD and cannabis has helped so much! I’ve put on a good amount of weight thanks to cannabis
