“A number of studies have consistently shown that cannabinoids are able to prevent or reduce carcinogenesis in different animal models of colon cancer.
Cannabinoids, via CB1 and possibly CB2 receptors, suppress proliferation and migration and stimulate apoptosis in colorectal cancer cells.
Convincing scientific evidence suggests that cannabinoids, in addition to their well-known use in palliative care in oncology (e.g. improvement of appetite, attenuation of nausea associated to antitumoral medicines, alleviation of moderate neuropathic pain) can reduce, via antiproliferative and proapoptotic as well as by inhibiting angiogenesis, invasion and metastasis or by attenuating inflammation, the growth of cancer cells and hinder the development of experimental colon carcinogenesis in vivo.”
