Dear Editor,

With March being recognised in the US as Colorectal Cancer Awareness Month, I am writing to highlight the potential positive effects of using cannabis in the treatment of colorectal cancer. I declare that I am not a health professional; however, I have been successfully treating my prostate cancer naturally with medical cannabis successfully for the past 13 years.

It is important to note that while research is ongoing, current evidence suggests that cannabis and its components, known as cannabinoids, offer several benefits for individuals affected by this disease.

One of the primary reported benefits of cannabis for all cancer patients, including those with colorectal cancer, is symptom management of patients undergoing conventional cancer treatments such as chemotherapy, who often experience debilitating side effects like nausea, vomiting, pain, and loss of appetite. There is much scientific evidence indicating cannabis alleviates these symptoms.

Beyond symptom relief, research suggests that cannabinoids possess anti-tumour properties. Studies indicate that compounds like tetrahydrocannabinol (THC) and cannabidiol (CBD) found in cannabis slow the growth of cancer cells and induce apoptosis or cell death.

Research from Penn State University’s Dr Kent Vrana, director of the Pennsylvania-approved Medical Marijuana Academic Clinical Research Center, has shown that certain cannabinoids are effective at killing colon cancer cells in laboratory settings, setting the stage for exploring the value of medical cannabis in treating cancer.

Additionally, studies have indicated that cannabis is believed to be responsible for the spread of aggressive cancer cells and that THC also has anticancer effects on tumours by promoting cancer cell death through autophagy.

There is also evidence suggesting that cannabis may enhance the effectiveness of conventional cancer treatments when used in conjunction with them. Moreover, cannabis, particularly its THC component, may be effective in reducing chronic pain, especially neuropathic pain, which is often experienced by cancer patients.

For patients with difficulties in oral administration due to swallowing issues or severe nausea and the resultant “high”, cannabis suppositories offer an alternative method. This route allows for direct absorption into the bloodstream and area of most concern. Tommy Chong, the famous Canadian American comedian, actor, and musician, is a colorectal cancer survivor who has spoken about using cannabis suppositories as part of his treatment regimen.

Overall, the use of cannabis may contribute to an improved quality of life for colorectal cancer patients by managing distressing symptoms and potentially offering anti-tumour effects.

Patients considering cannabis as part of their cancer care should always consult with their health-care provider to discuss potential benefits and risks as well as possible interactions with other medications.
