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. This is vital because lives are at stake. If someone chooses to reject conventional cancer treatment in favour of unproven alternatives, including cannabis, they may miss out on treatment that could save or significantly lengthen their life.
They may also miss out on effective symptom relief to control their pain and suffering, or the chance to spend precious time with their loved ones.
Furthermore, many of these unproven therapies come at a high price, and are not covered by the NHS or medical insurance. And, in the worst cases, an alternative therapy may even hasten death.
They can increase the heart rate, which may cause problems for patients with pre-existing or undiagnosed heart conditions. They can also interact with other drugs in the body, including antidepressants and antihistamines.
And they may also affect how the body processes certain chemotherapy drugs, which could cause serious side effects. Within a matter of hours she was in hospital in a coma. When conventional treatment fails, there is little chance that turning to an unproven alternative touted on the internet will provide a cure. But pharma companies are not stupid, and they are quick to jump on promising avenues for effective therapies.
And there are many ways that these compounds can be patented — for example, by developing more effective synthetic compounds or better ways to deliver them. This is also a false and misleading argument, analogous to suggesting that patients in pain should buy heroin or grow opium poppies rather than being prescribed morphine by a doctor. The best way to ensure that the benefits of cannabinoids — whether natural or synthetic — are brought to patients is through proper research using quality-controlled, safe, legal, pharmaceutical grade preparations containing known dosages of the drugs.
To do this requires time, effort and money, which may come from companies or independent organisations such as charities or governments. And, ultimately, this investment needs to be paid back by sales of a safe, effective new drug. We would also hope that if any cannabinoids are shown to be safe and effective enough to make it to the clinic, they would be available at a fair price for all patients that might benefit from them.
It is not for Cancer Research UK to comment on the legal status of cannabis, its use or abuse as a recreational drug, or its medical use in any other diseases. But we are supportive of properly conducted scientific research that could benefit cancer patients. 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. Conclusions Cannabis plants produce a substantial amount of cannabinoids and other secondary metabolites. Conflict of Interest The authors declare that they have no conflict of interest.
