Inhibition of tumor angiogenesis by cannabinoids

“Cannabinoids, the active components of marijuana and their derivatives, inhibit tumor growth in animal models… Because the generation of a new vascular supply (angiogenesis) is causally involved in the progression of the majority of solid tumors, the aim of this study was to test whether cannabinoids inhibit tumor angiogenesis.”

 …In the context of the renaissance in the study of the therapeutic effects of cannabinoids, our findings show that these compounds may be considered promising anti-tumoral agents as they inhibit tumor angiogenesis and growth in vivo with no significant side effects.

 This report provides a mechanistic basis for the anti-tumoral action of cannabinoids and a novel pharmacological target for cannabinoid-based anti-tumoral therapies…”
