Study: Synthetic CBD Administration Associated With Anti-Cancer Activity In Patients

London, United Kingdom: Patients with advanced forms of cancer exhibit a clinical response to the long-term use of synthetic CBD, according to data published in the journal Anticancer Research.

British investigators assessed the effects of twice-daily CBD administration on 119 cancer patients over a four-year period. Synthetic CBD oil extracts were provided by the British biotechnology firm STI Pharmaceuticals. Subjects consumed the oil for a minimum period of six months.

Authors reported that over 90 percent of subjects exhibited a clinical response to CBD treatment, with some patients experiencing a reduction in tumor size and tumor cell proliferation.

Numerous prior studies have demonstrated cannabinoids, particularly CBD and THC, to possess anti-cancer activity in preclinical models. To date, however, this activity has not yet been replicated in controlled human trials.

Authors concluded: “The fact that we have been able to document improvement … strongly supports further studies of CBD-based products in cancer patients who have exhausted standard treatments.”
