Most of the population at risk

Cancer is one of the most common serious diseases that can affect any of us. For example, in the US, cancer is diagnosed in 39% of the population at some point in their lives.

Oncologists, more than all other doctors, are proponents of using and implementing medical cannabis in cancer treatment, but the situation related to the illegality of cannabis and the related approach of the governments of many current states significantly slows down the further research needed to optimize cancer treatment with cannabinoids.

For example, the US federal government, despite many cases where cannabis has been shown to significantly relieve or completely eliminate the symptoms of not only cancer, still does not recognize cannabis as a drug with therapeutic potential and classifies it as a Schedule I drug, along with truly dangerous substances like heroin. On the other hand, we have staunch "charlatans" who present cannabis as a panacea capable of curing absolutely anything. So where is the truth?

Cannabis as a cure for cancer

Dr. Abrams, an advocate of medical cannabis and one of the most prominent oncologists and cancer researchers, points to the meaning of the word "cure" and urges caution.

"Cure is a word very often used in the field of oncology. It usually implies that the patient has survived 5 years without recurrence of that type of cancer. Nowadays, thanks to advances in diagnostics and conventional therapy, we are able to cure more types of cancer than when I started my career as an oncologist."

As a specialist in integrative medicine and cancer at the UCSF (Osher Center for Integrative Medicine at Mount Zion) in San Francisco, Dr. Abrams observes the following:

"As an oncologist working in the field for 33 years, I would guess that many of my patients use or have used cannabis. So if cannabis can truly cure cancer, how is it that I don't have more survivors among my patients? What we do know for sure is that cannabis can very effectively suppress the symptoms of cancer and the side effects of treatment such as nausea, vomiting, loss of appetite, pain, depression, anxiety, or sleep problems."

Dr. Abrams' opinion clearly reflects the general view of oncology: there is no doubt that medical cannabis can suppress the health problems associated with cancer, but whether it can definitively cure cancer is not clear.

Does it cure or help?

Unfortunately, cancer is a disease that affects a large proportion of the population, so it is understandable that those affected want to believe that cannabis can truly cure cancer. Especially oils and concentrated extracts from medical cannabis have been and remain the focus of interest in connection with cancer treatment, because the internet is full of stories about people who claim to have cured their disease with these products. However, Dr. Abrams warns:

"In these stories, I've noticed one thing: people who claim to have beaten cancer with cannabis forget to mention that they were also exposed to conventional treatment. If someone really beat cancer using only medical cannabis (cancer other than skin cancer), they should submit their findings and treatment documentation to the National Cancer Institute's Office of Cancer Complementary and Alternative Medicine or to the Best Case Scenario website for alternative treatments so that all cases can be properly documented and used for further research."

One of the main extracts used today is CBD oil, which does not have the same legislative restrictions as THC products.

Research is still ongoing

In the quest for a cancer cure, the potential of cannabis has been investigated in many studies focusing on cannabinoids and the endocannabinoid system, many of which have yielded very interesting findings. Among the most significant are studies that have shown that cannabinoids can suppress or stop the growth of cancer cells in cancers such as breast, brain, liver cancer, pheochromocytoma, melanoma, leukemia, and others.

Another important property of cannabinoids is their ability to trigger so-called apoptosis, i.e., programmed cell death of cancer cells, and to stop angiogenesis - the production of new blood capillaries in growing tumors.

Furthermore, for example, a study from Complutense University in Madrid found that an injection of synthetic THC can help two-thirds of mice studied in connection with brain tumors. In one third, THC significantly prolonged the lifespan of the mice, while in the other third, it completely eliminated the spreading malignant tumors.

Research into cannabis treatment is very promising, but it is still only in the preclinical phase, i.e., in animal testing. Therefore, before we can say with 100% certainty that medical cannabis can cure cancer, proper clinical trials in humans must be conducted.

Another obstacle is the diversity of cancer, and we must realize that the term cancer encompasses a whole range of diseases characterized by abnormal cell growth. So, unfortunately, it is unlikely that cannabis alone can definitively cure all types of cancer; rather, a combination of cannabis treatment with, for example, other conventional or complementary alternative treatments is expected.

The situation related to the illegality of cannabis in many countries significantly hinders and slows down the progress that needs to be made for the successful integration of cannabis into clinical treatment and clinical trials. In the Czech Republic, for example, the International Institute of Cannabis and Cannabinoids is progressive in this area:

"The founders of ICCI bring together very diverse expertise: clinical and basic research, consulting and management, patient rights protection, preparation of legal analyses and documents for legislation, institutionalized lobbying at the level of governments and legislative bodies, biostatistics and medical informatics, development of safety protocols (typically quality management standards for cannabis cultivation and laboratory analyses), manufacturing and distribution of cannabis products, and last but not least, international business. This unique combination allows us to create a successful global project with unique resources and experience." (ICCI)

At a time when medical cannabis is becoming less and less of a taboo and when more and more people are inclined to believe that it can truly help in treatment, a positive development of the whole situation can certainly be expected.
