I have just been prescribed the above.
Or could they play a role in causing cancer? In experiments with mice, animals given very high doses of purified THC seemed to have a lower risk of developing cancer, and there has been some research suggesting that endocannabinoids cannabinoids produced by the body can suppress tumour growth.
This is mainly because most people who use cannabis smoke it mixed with tobacco, a substance that definitely does cause cancer. In some parts of the world — including the Netherlands — medical use of marijuana has been legalised for palliative use relieving pain and symptoms , including cancer pain.
But one of the problems of using herbal cannabis is about dosage — smoking it or taking it in the form of tea often provides a variable dose, which may make it difficult for patients to monitor their intake. 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.
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 , These effects are partially connected with a modulation of the activity of extracellular proteases and their inhibitors 86 , The pharmacological inhibition of ceramide biosynthesis and the expression of p8 protein lead to the prevention of the mentioned effects The studies conducted to date indicate that antiangiogenic and antimetastatic characteristics of CB receptor agonists, similar to their antiproliferative effects, rely on the stimulation of ceramide biosynthesis and a modulation of pathways involving p8 protein.
Cannabinoids that are not agonists of CB receptors CBD , have also been shown to exhibit such properties. Increased levels of FAAH substrates e. Data collected to date regarding anticancer effects of cannabinoids are almost completely limited to preclinical studies conducted on cell lines and animal models.
The first experiment that was conducted on human subjects was a pilot clinical study on nine terminal patients with recurrent glioblastoma who were resistant to the standard therapy Patients received THC intratumorally.
This way of administration was safe and patients did not exhibit any overt psychoactive effects. In some patients the tumor growth rate decreased. Changes observed upon THC administration in two patients can be connected with anticancer effect of THC according to previous preclinical studies decreased cell proliferation, occurrence of apoptosis Despite these interesting observations, it is not possible to draw significant conclusions from the study on a group of nine.
This shows a need for further clinical trials, which could help to assess the dosage and the potential interaction of cannabinoids with other substances.
These studies are currently ongoing or have ended recently, but the results have not been published to date. Cannabis plants produce a substantial amount of cannabinoids and other secondary metabolites. It has been demonstrated that extracts of Cannabis exhibit stronger effects on the subjects with spasticity than pure THC Some cannabinoids have been demonstrated to attenuate psychoactive effects of THC or smoked marijuana 13 , Pure cannabinoids are more convenient for study and to a subsequent standardization as a medical preparation, but still Cannabis extracts with specified amounts of cannabinoids seem to be valuable aim for further studies, also as potential anticancer agents.
An interesting idea is a combination of cannabinoids with conventional anticancer drugs, which can exhibit synergistic potential. The promising results from studies on animal models of glioblastoma treated with THC and temozolomide have led to, mentioned above, clinical trial of this chemotherapeutic agent and Sativex 94 , Similar observations from the study on pancreatic adenocarcinoma showed that gemcitabine administered with cannabinoids synergistically inhibited cancer cell growth To date, Cannabis or its preparations have found an application in a palliative medicine due to its analgesic and antiemetic effects, an attenuation of the side effects of chemotherapy or a capacity to treat spasticity in multiple sclerosis.
We are still initial stages of incorporating Cannabis products in the clinical care. There is still a lack of profound safety and efficacy clinical trials and it is very difficult or even impossible to assess the potential benefits and risk of using cannabinoids in many cases.
Many aspects wait for an elucidation: The most common way of using recreational marijuana is smoking, which is unsuitable way of an administration from a medical point of view. Another important issue is the lack of easy accessible biomarkers showing the responsiveness of patients to a cannabinoid treatment. Moreover, antitumor effects of cannabinoids have to overcome their known immunosuppressive effects which can be potentially protumorigenic.
The interactions between cannabinoids and classical cytotoxic agents have to be precisely defined. These observations lead us to the conclusion, that further profound studies are doubtlessly needed to verify the idea of introducing cannabinoids into the cancer treatment.

Abstract To date, cannabinoids have been allowed in the palliative medicine due to their analgesic and antiemetic effects, but increasing number of preclinical studies indicates their anticancer properties.
Introduction Nowadays, we observe an increasing public and scientific interest in the medical applications of Cannabis plants. Endocannabinoid system and cancer Despite numerous studies conducted during the last decade, there are still inconsistent data regarding the exact role of cannabinoid system in cancer development. Open in a separate window. Cannabinoids and the immune system The mechanism of the immunomodulatory effects of cannabinoids is still not fully elucidated.
Selectivity and stimulation of viability Viability of noncancerous cells seems to remain unchanged or sometimes even elevated by cannabinoids 34 , 35 , 36 , 39 , Inhibition of angiogenesis and metastasis Besides the above described proapoptotic effect in cancer cells, cannabinoids exhibit some other important and potentially valuable properties.
Anticancer effects of cannabinoids in clinical trials Data collected to date regarding anticancer effects of cannabinoids are almost completely limited to preclinical studies conducted on cell lines and animal models.
