There are also many cannabis based products available online without a prescription. The quality of these products can vary. It is impossible to know what substances they might contain. They could potentially be harmful to your health and may be illegal.

Nabilone is a drug developed from cannabis. It is licensed for treating severe sickness from chemotherapy that is not controlled by other anti sickness drugs. It is a capsule that you swallow whole.

Hemp oil comes from the seeds of a type of cannabis plant that doesn’t contain the main psychoactive ingredient THC. Hemp seed oil is used for various purposes including as a protein supplement for food, a wood varnish and an ingredient in soaps.

There are different types of oil made from parts of the cannabis plant. Some are sold legally in health food stores as a food supplement. Other types of oil are illegal.

This means a cannabis based product used to relieve symptoms.

Research into cannabinoids and cancer.

Results have shown that different cannabinoids can:

Sativex is a cannabis-based medicine. It is licensed in the UK for people with Multiple Sclerosis muscle spasticity that hasn’t improved with other treatments. Sativex is a liquid that you spray into your mouth.

Scientists also discovered that cannabinoids can:

You could talk with your cancer specialist about the possibility of joining a clinical trial. Trials can give access to new drugs in a safe and monitored environment.

The results of one trial showed that Sativex did not improve pain levels. You can read the results of the trial on our clinical trials website.

CBD oil comes from the flowers of the cannabis plant and does not contain the psychoactive substance THC. It can be sold in the UK as a food supplement but not as a medicine. There is no evidence to support its use as a medicine.

In 2021, scientists reported the final results of a phase 1 study to treat people with recurrent glioblastoma (a type of brain tumour that has come back). The study looked at Sativex in combination with the chemotherapy drug temozolomide.

Cannabis has been used medicinally and recreationally for hundreds of years.

Cannabis is a class B drug and illegal in the UK.

How you have it.

THC is a psychoactive substance that can create a ‘high’ feeling. It can affect how your brain works, changing your mood and how you feel.

A Cochrane review in 2015 looked at all the research available looking into cannabis based medicine as a treatment for nausea and sickness in people having chemotherapy for cancer. It reported that many of the studies were too small or not well run to be able to say how well these medicines work. They say that they may be useful if all other medicines are not working.

Cannabis is a plant. It is known by many names including marijuana, weed, hemp, grass, pot, dope, ganja and hash.

Prescription drugs such as Nabilone can cause side effects. This can include:

However, this phase 1 study only involved 27 patients, which was too small to learn about any potential benefits of Sativex. The study wanted to find out if Sativex and temozolomide was safe to take by patients.

There are internet scams where people offer to sell cannabis preparations to people with cancer. There is no knowing what the ingredients are in these products and they could harm your health. Some of these scammers trick cancer patients into buying ‘cannabis oil’ which they then never receive.

Medical cannabis.

A cannabis based medicine, Nabilone, is a treatment for nausea and vomiting.

Researchers now plan to run a larger phase 2 trial, to find out if this treatment is effective and who might benefit from it.

Cannabis that contains high levels of THC can cause panic attacks, hallucinations and paranoia.

Cannabis is a class B drug in the UK. This means that it is illegal to have it, sell it or buy it.

We need more research to know if cannabis or the chemicals in it can treat cancer.

CBD oil comes as a liquid or in capsules.

They also observed that 83 out of 100 people (83%) were alive after one year using Sativex, compared to 44 out of 100 people (44%) taking the placebo.

So far, the best results from lab studies have come from using a combination of highly purified THC and cannabidiol (CBD), a cannabinoid found in cannabis plants that counteracts the psychoactive effects of THC. But researchers have also found positive results using man-made cannabinoids, such as a molecule called JWH-133.

This trial is being extended into phase 2 (known as ARISTOCRAT) to explore if this treatment is effective and which patients are most likely to respond to this treatment. If the trial is , it is set to launch at 15 NHS hospitals in 2022, with over 230 patients to be recruited. To find out more about this work, you can listen to our podcast – That Cancer Conversation – where we hear from Professor Susan Short, one of the researchers leading this study.

Much of the research into cannabinoids and cancer so far has been done in the lab.

Cannabis in clinical trials.

There are still many unanswered questions around the potential for using cannabinoids to treat cancer. It’s not clear:

Cannabis is an illegal (class B) drug in the UK and there are further risks associated with using black market or home-made preparations, particularly cannabis oil, such as toxic chemicals left from the solvents used in the preparation process.

Cannabinoids may also have potential in combating the loss of appetite and wasting (cachexia) experienced by some people with cancer, although so far clinical evidence is lacking. One clinical trial comparing appetite in groups of cancer patients given cannabis extract, THC and a placebo didn’t find a difference between the treatments, while another didn’t show any benefit and was closed early.

Our funding committees have previously received other applications from researchers who want to investigate cannabinoids but these failed to reach our high standards for funding. If we receive future proposals that meet these stringent requirements, then there is no reason that they wouldn’t be funded, assuming we have the money available.

Put simply, Petri dishes are not people. Most chemicals that show promise in lab or animal experiments turn out not to work as well as hoped when tested in patients. These kinds of human studies, known as clinical trials, are the only way we can really know if a cancer treatment is effective. There’s more about clinical trials on our website: http://www.cancerresearchuk.org/cancer-help/trials/types-of-trials/

We’re supportive of properly conducted scientific research into cannabis and its derivatives that could benefit cancer patients. Many researchers are actively exploring this approach, and Cancer Research UK is supporting, and will continue to support, scientifically robust research into cannabis and cannabinoids that reaches the high-quality standards set by our funding committees.

Can cannabis prevent cancer?

This is because virtually all the scientific research investigating whether cannabinoids can treat cancer has been done using cancer cells grown in the lab or animals. While these studies are a vital part of research, providing early indications of the benefits of particular treatments, they don’t necessarily hold true for people.

The first thing to point out is that the NCI’s cancer information website is an independent resource for doctors and the patients, and is not a statement of NIH, NCI or US government policy.

There’s good evidence that cannabinoids may be beneficial in managing cancer pain and side effects from treatment.

Although centuries of human experimentation tell us that naturally-occurring cannabinoids are broadly safe, they are not without risks. They can increase 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.

Can cannabinoids treat cancer?

In some parts of the world, medical marijuana has been legalised for relieving pain and symptoms (palliative use), including cancer pain. But one of the problems with using herbal cannabis is managing the dose. Smoking cannabis or taking it in the form of tea often provides an inconsistent 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.

Cannabis is still classified as a class B drug in the UK, meaning that it is illegal to possess or supply it. Cancer Research UK can’t comment on the legal status of cannabis, its use as a recreational drug, or its medical use in any other diseases. But we are supportive of properly conducted scientific research into cannabis and its derivatives that could benefit cancer patients.

We’ve also supported a trial that’s testing the benefits of a man-made cannabinoid called dexanabinol in patients with different types of advanced cancer. The trial finished recruiting in 2015 and researchers established a safe dose of the drug, but further development of the drug was stopped due to a lack of evidence around the drug’s effectiveness. Full trials results are yet to be published.

We’ve recently seen stories in the press claiming that the US government has “admitted that cannabis kills cancer” (for example, this one in the Metro), based on the observation that pages on the US National Cancer Institute information website carry details of the current scientific evidence around the effects of cannabis and cannabinoids on cancer cells in the lab and animal models.

We understand the desire to try every possible avenue when conventional cancer treatment fails. But there is little chance that an unproven alternative treatment bought online will help, and it may well harm. We recommend that cancer patients talk to their doctor about clinical trials that they may be able to join, giving them access to new drugs in a safe and monitored environment.

Cannabis-based medicines were rescheduled under UK law in 2018 allowing doctors to prescribe these treatments to patients for a wide range of conditions. We are interested in the evaluation and development of novel cannabinoid therapies targeting two main areas: 1) inflammation & cancer, with a current focus on pancreatic ductal adenocarcinoma (PDAC) and 2) acute/ post- surg ical, neuropathic and cancer -related pain .

Pain Up to 50% of all cancer patients experience pain, and as many as 90% with advanced cancer live with chronic debilitating pain that can be difficult to treat. The pain contributes significantly to increased morbidity and reduced quality of life, characteri s ed by fatigue, depression, insomnia, and weight loss. The evaluation and development of cannabinoid compounds may lead to novel therapies which provide better pain relief and improve the quality of life in patients with chronic pain conditions.

Inflammation and Cancer.

Why it is important.

Pain There is an increasing unmet clinical need for several types of pain treatment. Many c urrent pharmacological treatments have limited efficacy and significant side-effects. Chronic neuropathic pain represents a great need – between 4 and 12 patients are treated before a single patient reports 50% pain relief, and clinical trials in chemotherapy-induced painful neuropathy have been disappointing. Advances in the non-opioid treatment of acute and chronic pain, such as with novel cannabinoids, are therefore urgently needed.

Inflammation & Cancer Cannabinoids have shown merits in not only alleviating the unwanted side – effects of cancer treatments but have also displayed promising pre-clinical antitumour properties, through modulating processes which include apoptosis and autophagy. Co-administration of cannabinoids with cytotoxic therapies may enhance the potency of these outcomes . In cancers that are refractory to systemic therapy, t hese synergistic effects warrant further investigation to select combinations for clinical translation and evaluation .

Inflammation and Cancer Understanding the specific molecular and biological actions of cannabinoids in the context of inflammation and cancer will help to reveal novel targets for therapeutic interventions. The study of combination treatments will provide data to accelerate translation to clinical trials.

Inflammation & Cancer We investigate the mechanism of action of cannabinoids and relevant compounds at a molecular level through the study of relevant oncological signalling pathways. We also evaluate the efficacy and interaction of cannabinoids in combination with cytotoxic and immune-modulating therapies for the treatment of cancer.

We are in the development phase for a randomised controlled trial evaluating cannabis-based medicinal products in the treatment of acute post-operative pain, nausea and vomiting. The first stage of this process which involves a comprehensive patient and public involvement program has been completed and published in Cannabis and Cannabinoids Research.

There are a number of other ongoing translational projects and we welcome industry/academic collaborations to accelerate this process. These include a collaborative protocol for a placebo-controlled double-blind Phase II virtual trial with a pilot & feasibility phase to assess the efficacy and safety of cannabidiol (CBD) for the treatment of home self-isolating health care worker patients with mild COVID-19 .

Collaborators.

Pain We aim to test the efficacy and potency of a range of novel cannabinoid related compounds, including those that target receptors such as the cannabinoid receptors CB1 and CB2, and to develop new analgesic treatments for use in the clinic. These novel agents are evaluated using in vitro models of hypersensitivity in cultured neurons from rodent and human sensory ganglia. We have recently shown that Cannabidiol (CBD) at low doses , corresponding to plasma concentrations observed physiologically , inhibits or desensitizes neuronal TRPV1 signalling by inhibiting the adenylyl cyclase – cAMP pathway, which is essential for maintaining TRPV1 phosphorylation and sensitization. CBD also facilitated calcineurin-mediated TRPV1 inhibition. These mechanisms may underlie nociceptor desensitization , and the therapeutic effect of CBD in animal models and patients with acute and chronic pain.
