CBD KILLS CANCER CELLS BUT LEAVES HEALTHY CELLS UNTOUCHED

The race is now on to figure out how CBD produces these anti-cancer effects.

Despite a growing number of reports and case studies regarding the cancer-busting properties of cannabis, clinical use of cannabinoids as a treatment for cancer is unlikely to get the green light until scientists can figure out exactly how it interacts with tumours. While research on this subject has been frustratingly slow, a series of new studies has begun to shed light on the potent anti-cancer properties of CBD.

Among these is a research project currently being conducted at the University of Newcastle in Australia, where scientists have been comparing the efficacy of different cannabis cultivars at fighting cancer. Results have indicated that a high-CBD strain known as ‘Eve’ is significantly better at killing cancer cells than other varieties containing less CBD but more THC.

Commenting on these findings, lead researcher Dr Matt Dun explained that “we initially used leukaemia cells and were really surprised by how sensitive they were [to Eve]”. The team later tested their high-CBD cannabis on paediatric brainstem glioma cells, and found that it was equally effective at killing off these cancerous cells.

Significantly, though, Dun says that “the cannabis didn’t kill normal bone marrow cells, nor normal healthy neutrophils [white blood cells].” This is hugely important, as it suggests that CBD works via some sort of “cancer-selective mechanism,” whereby it is able to recognise and target tumours while leaving healthy cells untouched.

The race is now on to figure out how CBD produces these anti-cancer effects, with hopes high that cannabis could soon become an approved cancer treatment.

So far, studies have indicated that CBD targets cancer via a number of different pathways. For instance, it is generally accepted that CBD differs from other cannabinoids like THC in that it has a low affinity for the body’s cannabinoid receptors, and instead binds with other kinds of receptors known as G-protein coupled receptors (GPCRs). One such receptor, known as GPR55, has been found to play a significant role in the development of numerous types of cancer, and researchers theorise that CBD may interfere with this process by binding to this receptor[i].

Other studies, however, have indicated that CBD does interact with cannabinoid receptors, and that this mediates the formation of two key enzymes that synthesise reactive oxygen species. These, in turn, stimulate apoptosis in cancer cells, essentially causing them to self-destruct[ii].

While CBD is widely seen as a potential game-changer in cancer treatment, several other compounds found in cannabis have also been found to help kill tumours. Cannabigerol (CBG), for instance, has shown great promise as a treatment for colon cancer, while the activation of cannabinoid receptors has been found to stimulate the release of proteins that prevent prostate cancer from developing[iii].

In spite of all this evidence, however, many questions still remain regarding how cannabis interacts with cancer cells, as well as which cannabinoids are most effective for treating which types of cancer. Because of this, doctors are not yet in a position to prescribe cannabis to cancer patients, or to advise those suffering from the condition to self-medicate with marijuana.

Yet as interest in medical cannabis as a treatment for cancer continues to skyrocket, many within the scientific community are now optimistic that marijuana could soon become a key ally in the fight against the deadly illness.
