So researchers are turning to alternative dosing methods, such as mouth sprays, which deliver a reliable and regulated dose. We want to see safe, reliable and effective treatments become available for patients as quickly as possible. We receive no government funding for our research, and it is all paid for by the generosity of the public. This is obviously not a bottomless purse, and we do not have financial reserves to draw on. Because of this limitation, we can only fund the very best research proposals that come to us that will bring benefits to people with cancer.
Our funding committees have previously received other applications from researchers who want to investigate cannabinoids that have failed to reach our high standards for funding.
If we receive future proposals that do meet these stringent requirements, then there is no reason why they would not be funded — assuming we have the money available to do so. But whole plants or other organisms are a complex mix of hundreds of chemicals not all of which may be beneficial and contains low or variable levels of active ingredients. This makes it difficult to give accurate doses and runs the risk of toxic side effects. Foxgloves — a source of medically useful chemicals.
These drugs are now used to treat many thousands of people around the world with heart failure and other cardiac problems. But the entire plant itself is highly toxic, and eating just a small amount can kill. But this naturally-occurring chemical causes severe stomach irritation, which led to the German company Bayer developing an alternative version — acetylsalicylic acid — which was kinder to the tummy. Aspirin is now arguably one of the most successful drugs of all time, and is still being investigated for its potential in preventing or even treating cancer.
As we said above, there is no good evidence that natural cannabinoids, at the doses present in simple cannabis preparations, can treat cancer in patients. There is a strong and persistent presence on the internet arguing that cannabis can cure cancer. Despite what the supporters of these sources may claim, videos and stories are not scientific evidence for the effectiveness of any cancer treatment. We know nothing about their medical diagnosis, stage of disease or outlook.
People who make these bold claims for cannabis only pick their best cases, without presenting the full picture. This highlights the importance of publishing data from scientifically rigorous lab research and clinical trials. Firstly because conducting proper clinical studies enables researchers to prove that a prospective cancer treatment is safe and effective.
And secondly because publishing this data allows doctors around the world to judge for themselves and use it for the benefit of their patients. Internet anecdotes and videos prove nothing and benefit no-one — we need reliable, scientific research, which as discussed above is exactly what is going on.
Not only to the thousands of our scientists, doctors and nurses who are working as hard as they can to find more effective treatments for the complex set of challenging diseases we call cancer, but also the hundreds of thousands of people in the UK and beyond who support this life-saving work through generous donations of money, energy and time. Our aim is to beat cancer, and we believe that the best way to do this through rigorous scientific research aimed at understanding cancer on a biological level and working out how to prevent, detect and treat it more effectively.
As a research-based organisation, we want to see reliable scientific evidence to support claims made about any cancer treatment, be it conventional or alternative. Dronabinol synthetic THC is approved also for nausea and vomiting due to chemotherapy and for the treatment of weight loss associated with AIDS. Medical Cannabis in the form of marijuana dried flowers and leafs is illegal in the USA at the federal level according to the Controlled Substances Act as a Schedule I substance, but some states have legalized it for medical purposes Besides palliative properties of cannabinoids, it has been shown in wide range of in vitro and animal models, that they also exhibit anticancer effects 7 , 15 , 16 , Despite numerous studies conducted during the last decade, there are still inconsistent data regarding the exact role of cannabinoid system in cancer development.
The upregulated expression of CB receptors and the elevated levels of endocannabinoids have been observed in a variety of cancer cells skin, prostate, and colon cancer, hepatocellular carcinoma, endometrial sarcoma, glioblastoma multiforme, meningioma and pituitary adenoma, Hodgkin lymphoma, chemically induced hepatocarcinoma, mantel cell lymphoma , but it is not always correlated with the expression level of these receptors in tissue of origin 7 , 11 , 18 , Furthermore, concentration of endocannabinoids, expression level of their receptors, and the enzymes involved in their metabolism frequently are associated with an aggressiveness of cancer.
This implies that an overactivation of endocannabinoid system might be protumorigenic and plays an essential role in the development of cancer 20 , On the other hand, there are reports indicating that an activation of the cannabinoid receptors can impair cancer development and hence endocannabinoid signaling can be antitumorigenic.
Furthermore, it has been shown that silenced expression of CB1 receptor leads to an acceleration of intestinal adenoma growth, whereas activation of this receptor attenuates its growth in murine model The elevated level of endocannabinoids has been shown to reduce the development of precancerous lesions in mouse colon On the other hand, there are reports that have indicated that under certain circumstances, cannabinoids can be protumorigenic 31 , 32 , It has been shown that CB1 and CB2 receptor agonists stimulate apoptotic cell death in glioma cells by induction of de novo synthesis of ceramide, sphingolipid with proapoptotic activity 34 , If this response fails, ER stress can lead to activation of intrinsic apoptosis pathway The known mechanisms responsible for the induction of apoptosis by cannabinoids.
It has been demonstrated that process of autophagy is upstream of apoptosis in mechanism of cell death induced by cannabinoids. An inhibition of autophagy prevents apoptosis induced by cannabinoids, while an inhibition of apoptosis prevents only cell death but not the autophagy 39 , 41 , 42 , It has been shown that cannabinoids induce process of autophagy in cancer cell lines such as glioma, melanoma, hepatic, and pancreatic cancer 39 , 41 , 42 , Moreover, some additional mechanisms have been demonstrated to contribute to the process of an induction of cell death by cannabinoids in certain cell lines.
Similar results have been obtained in prostate carcinoma cells Table S1 Cannabinoids devoid of psychoactive properties also exhibit anticancer potential. They do not affect CB receptors directly and their exact mechanism of action is still not fully elucidated.
Another interesting explanation is that CBD can prevent the degradation of anandamide AEA and subsequently leads to increased endocannabinoid concentration by acting as an inhibitor of fatty acid amide hydrolase FAAH 52 , This notion raises the possibility that the observed actions of CBD can be, in fact, partially the result of an elevated level of AEA.
These observations are in line with the described earlier relations between endocannabinoids and cancer development.
Most of the research implicates that the action of CBD and other cannabinoids devoid of psychoactive properties is not linked to a direct activation of the CB receptors. However, there are reports suggesting that CBD can induce apoptosis in cancer cells partially via direct or indirect activation of CB2 receptor Recent studies have shown that CBD reduces cancer cell viability in many cancer types such as neuroblastoma, glioblastoma, melanoma, leukemia, colorectal, breast, lung, or prostate cancer Table S1 41 , 50 , 51 , 54 , 56 , 57 , 58 , The mechanism of the immunomodulatory effects of cannabinoids is still not fully elucidated.
Research has been focused mainly on the CB2 receptor, mostly due to its expression primarily in cells of the immune system. CB1 receptors have been noticed in the T lymphocytes and it is proposed that their activation may be connected with the cytokine biasing induced by cannabinoids The highest level of CB2 expression has been observed in B cells, followed by NK cells, monocytes, polymorphonuclear neutrophils, and T cells It has been shown that the expression level of CB2 correlates with the cell activation state and with the presence of immune modulators The immune system is postulated to be involved in the control of growth and development of many types of cancer.
One of the key regulators of the antitumor immune response is cytokines profile. It is postulated that a Th1 response is crucial for an effective immune response against many tumors Phytocannabinoids with high affinity for CB2 receptors, such as THC, exhibit modulatory effects on both cellular and humoral immunity.
Nonpsychotropic cannabinoids with low affinity for CB receptors have also been proven to exhibit immunomodulatory action. Most of the studies indicate that cannabinoids exhibit immunosuppressive action The most extensively examined immunomodulatory effects of cannabinoids in context of cancer are regarding the changes in the activity of T cells. It has also been proposed that cannabinoids can affect T cells by the induction of apoptosis 73 , Another possibility is that cannabinoids effects on immune cells are at least partially induced indirectly via other suppressive mechanisms such as release of cortisone The effects on the Th17 cells subsets have not been fully described to date.
Interestingly, CB receptors seem to take part in the modulation of those phenomena Indeed, there are reports indicating the suppression of anticancer immune response by THC. It has been demonstrated that THC suppresses host immune reactivity against cancer in murine lung cancer model Lewis lung carcinoma, 3LL and line 1 alveolar cell carcinoma L1C2 , leading to the increase in the tumor growth CB2 receptors antagonists also blocked the effects of THC administration.
Similar results were obtained in the study of mouse mammary carcinoma. It has been demonstrated that THC exposure leads to the significant increase in the 4T1 carcinoma growth and metastasis due to the inhibition of the specific antitumor immune response Observed effects were mediated by CB2 receptors It is possible that tumors originating from tissues of low CB receptors expression would be significantly less sensitive to cannabinoids anticancer action and, eventually, due to THC immunosuppressive properties, such tumors may find a favorable environment for growth and development.
It is also possible that anticancer properties of cannabinoids may be compensated by their immunosuppressive action, finally leading to promotion of the tumor growth.
Chronic inflammation has been associated with the development of neoplasia; therefore, reducing inflammation may, to some extent, contribute to the prevention of carcinogenesis. Viability of noncancerous cells seems to remain unchanged or sometimes even elevated by cannabinoids 34 , 35 , 36 , 39 , On the other hand, cannabinoids can trigger apoptotic cell death in some types of nontransformed cells, especially those of high proliferative properties such as endothelial cells The cellular response to cannabinoids relies on different mechanisms in cancerous and noncancerous cells.
It has been demonstrated in vitro that cannabinoids can exhibit a stimulatory activity in nanomolar concentration and an inhibitory activity in micromolar concentration biphasic response , which significantly exceeds concentrations usually detected in blood of marijuana smokers Concentration of THC used in described experiment corresponded to its serum concentration obtained by smoking or oral administration of THC Besides the above described proapoptotic effect in cancer cells, cannabinoids exhibit some other important and potentially valuable properties.
It has been demonstrated that they can inhibit angiogenesis by blocking an activation of the vascular endothelial growth factor VEGF pathway. Cannabinoids have also been shown to reduce spontaneous and induced metastases in animal models and to inhibit an invasiveness of cancer cells in vitro breast, lung, cervical cancer, and glioma 86 , 87 , 88 , 89 , There's also lots of really good information in our blog Cannabinoids for treating cancer?
Our cancer information nurses are just on the other end of the phone if you have any questions, too: Thanks for sharing this article. The problem is that this may have nothing to do with her taking cannabis oil.
A small percentage of patients inexplicably go into remission without any sort of therapy. This medscape article describes this phenomenon. Proving the efficacy of cancer oil in a sample size of one case is impossible. This woman's cancer may have reacted to the cannabis oil though whether the active ingredients can survive the digestive process is debated or she may have experienced spontaneous remission.
