Colitis itself refers to inflammation in your colon. Because there are many different types of colitis, the symptoms often reveal the type of colitis patients have. Treatments will vary according to which variety of colitis you have.


Ulcerative colitis is the most common variety of the disease, affecting some 907,000 Americans. Symptoms may vary from person to person, but generally include one or more of the following:

  • Abdominal pain and cramping
  • Anemia
  • Dehydration
  • Diarrhea — sometimes with blood or pus
  • Fatigue
  • Fever
  • Inability to defecate, regardless of urgency
  • Joint pain
  • Loss of appetite
  • Nausea
  • Rectal bleeding
  • Rectal pain
  • Urgency to defecate
  • Weight loss


Marijuana cannot treat all cases of colitis.However, some research suggests medical marijuana can alleviate the symptoms of colitis that co-occurs with IBS.As for the pain associated with colitis, there is ever-increasing evidence medical marijuana is a mild to moderate pain reliever in itself. There is also evidence it can work in conjunction with opiates to relieve chronic pain, while lowering the opiate dose necessary to relieve pain.

When it comes to nausea, vomiting, loss of appetite and weight loss, the evidence medical marijuana can treat these symptoms is staggering. These symptoms are some of the rare few for which the U.S. government has allowed medical marijuana treatment. As mentioned above, it is only allowed for specific conditions. However, there is no indication it does not work for other conditions. In fact, the evidence shows quite the opposite. Increased hunger and nausea alleviation are among the best-documented uses for medical marijuana.
