According to the investigators at the University of Salerno, cannabinoids (one of the compounds found in medical marijuana) limit cancer cell proliferation and induce tumor-selective cell death.

The authors of the scientific review concluded that, cannabinoids inhibit “tumor growth and migration, angiogenesis (the formation of new blood vessels to cancerous tumors), [and] metastasis (the transfer of malignant cells from one site to another).” They are also quoted as stating that, “Emerging evidence suggests that agonists of cannabinoid receptors … may offer a novel strategy to treat cancer.”
