Yet another study implies that the second-most common active ingredient in pot, cannabidiol, treats pain associated with breast cancer chemotherapy, as well as slows the progression of the disease.
Lead study author Sarah Jane Ward writes in the British Journal of Pharmacology that CBD treats the pain from the chemo drug Paclitaxel (PAC) without decreasing the poison's effectiveness or leading to addiction like morphine.
"Our data suggest that CBD is protective against PAC-induced neurotoxicity ... Furthermore, CBD treatment was devoid of other nervous system effects such as conditioned reward or cognitive impairment. CBD also did not attenuate the efficacy of PAC in inhibiting breast cancer cell viability. Taken together, adjunct treatment with CBD during PAC chemotherapy treatment may be safe and effective in the prevention or attenuation of CIPN."
