Inflammatory bowel diseases (mainly Crohn’s and colitis) are chronic, debilitating, non-infectious, inflammatory diseases of the digestive tract. Conventional treatment consists of anti-inflammatory and immunomodulating drugs. However, the rate of response to currently available treatments is limited to 40–60%, and many patients remain symptomatic despite maximal medical treatment. This study, conducted in collaboration with the Gastroenterology Unit at Meir Medical Center, is a large-scale, long-term study that included data on patients licensed to treat medical cannabis with inflammatory bowel disease to determine the effect of cannabis on disease symptoms on long-term treatment as well as side effects. Most patients reported significant improvement in their symptoms and the use of other medications after 1 year of cannabis consumption was significantly reduced.
STUDY POPULATION: 127 Crohn’s and colitis patients who received a license for use of medical cannabis (86 males, mean age 39.6).
STUDY PRODUCT: Half of the patients in the study received the company’s products regularly.
• During the study period, 127 patients received a license to use medical cannabis and entered the study.
• General improvement – the average Harvey-Bradshaw index, which measures the severity of the disease, improved from 14.0 to 7.0 (P <0.001).
• Weight gain – During follow-up of 3.6 years (median 44 months), there was a slight but statistically significant weight gain of 2 kg.
• Decrease in drug consumption – the need for other medications was significantly reduced.
• Improve in employment rates – employment among patients increased from 65% to 74%.
• From the study it can be concluded that most Crohn’s and colitis patients using cannabis are satisfied with a dose of 30 gram per month.
• No negative effects of cannabis use were observed on the patients’ social or occupational status.
• The side effects described by the patients were mild. The most common were dry mouth (63%), memory decline (34%), eye irritation (14%), dizziness, (13%) confusion (9%), and restlessness (8%).
