Discover what we know about cannabidiol in cancer treatment, including its potential in anti-cancer therapy. Cannabis is a plant and a class B drug. CBD oil is a chemical found in cannabis. Research is looking at the substances in cannabis to see if it might help treat cancer.

Marijuana and Cancer

Marijuana is the name given to the dried buds and leaves of varieties of the Cannabis sativa plant, which can grow wild in warm and tropical climates throughout the world and be cultivated commercially. It goes by many names, including pot, grass, cannabis, weed, hemp, hash, marihuana, ganja, and dozens of others.

Marijuana has been used in herbal remedies for centuries. Scientists have identified many biologically active components in marijuana. These are called cannabinoids. The two best studied components are the chemicals delta-9-tetrahydrocannabinol (often referred to as THC), and cannabidiol (CBD). Other cannabinoids are being studied.

At this time, the US Drug Enforcement Administration (DEA) lists marijuana and its cannabinoids as Schedule I controlled substances. This means that they cannot legally be prescribed, possessed, or sold under federal law. Whole or crude marijuana (including marijuana oil or hemp oil) is not approved by the US Food and Drug Administration (FDA) for any medical use. But the use of marijuana to treat some medical conditions is legal under state laws in many states.

Dronabinol, a pharmaceutical form of THC, and a man-made cannabinoid drug called nabilone are approved by the FDA to treat some conditions.

Types of marijuana compounds

Different compounds in marijuana have different actions in the human body. For example, delta-9-tetrahydrocannabinol (THC) seems to cause the “high” reported by marijuana users, and also can help relieve pain and nausea, reduce inflammation, and can act as an antioxidant. Cannabidiol (CBD) can help treat seizures, can reduce anxiety and paranoia, and can counteract the “high” caused by THC.

Different cultivars (strains or types) and even different crops of marijuana plants can have varying amounts of these and other active compounds. This means that marijuana can have different effects based on the strain used.

The effects of marijuana also vary depending on how marijuana compounds enter the body. The most common ways to use marijuana are in food (edible marijuana) and by smoking or vaping it (inhaled marijuana):

  • Edible marijuana: When taken by mouth, such as when it’s used in cooking oils, drinks (beer, tea, vodka, soda), baked goods (biscuits, brownies, cookies), and candy, the THC is absorbed poorly and can take hours to be absorbed. Once it’s absorbed, it’s processed by the liver, which produces a second psychoactive compound (a substance that acts on the brain and changes mood or consciousness) that affects the brain differently than THC. It’s important to know that the amount of THC in foods that have had marijuana added to them is often unknown and getting too much THC might cause symptoms of overdose.
  • Inhaled marijuana: When marijuana is smoked or vaporized, THC enters the bloodstream and goes to the brain quickly. The second psychoactive compound is produced in small amounts, and so has less effect. The effects of inhaled marijuana fade faster than marijuana taken by mouth.

How can marijuana affect symptoms of cancer?

A number of small studies of smoked marijuana found that it can be helpful in treating nausea and vomiting from cancer chemotherapy.

A few studies have found that inhaled (smoked or vaporized) marijuana can be helpful treatment of neuropathic pain (pain caused by damaged nerves).

Smoked marijuana has also helped improve food intake in HIV patients in studies.

There are no studies in people of the effects of marijuana oil or hemp oil.

Studies have long shown that people who took marijuana extracts in clinical trials tended to need less pain medicine.

More recently, scientists reported that THC and other cannabinoids such as CBD slow growth and/or cause death in certain types of cancer cells growing in lab dishes. Some animal studies also suggest certain cannabinoids may slow growth and reduce spread of some forms of cancer.

There have been some early clinical trials of cannabinoids in treating cancer in humans and more studies are planned. While the studies so far have shown that cannabinoids can be safe in treating cancer, they do not show that they help control or cure the disease.

Relying on marijuana alone as treatment while avoiding or delaying conventional medical care for cancer may have serious health consequences.

Possible harmful effects of marijuana

Marijuana can also pose some harms to users. While the most common effect of marijuana is a feeling of euphoria (“high”), it also can lower the user’s control over movement, cause disorientation, and sometimes cause unpleasant thoughts or feelings of anxiety and paranoia.

Smoked marijuana delivers THC and other cannabinoids to the body, but it also delivers harmful substances to users and those close by, including many of the same substances found in tobacco smoke.

Because marijuana plants come in different strains with different levels of active compounds, it can make each user’s experience very hard to predict. The effects can also differ based on how deeply and for how long the user inhales. Likewise, the effects of ingesting marijuana orally can vary between people. Also, some chronic users can develop an unhealthy dependence on marijuana.

Cannabinoid drugs

There are chemically pure drugs based on marijuana compounds that have been approved in the US for medical use.

  • Dronabinol (Marinol®/Syndros®) is a medicine containing delta-9-tetrahydrocannabinol (THC) and is approved by the US Food and Drug Administration (FDA) to treat nausea and vomiting caused by cancer chemotherapy as well as weight loss and poor appetite in patients with AIDS.
  • Nabilone (Cesamet®) is a synthetic cannabinoid that acts much like THC. It can be taken by mouth to treat nausea and vomiting caused by cancer chemotherapy when other drugs have not worked.

Nabiximols is a cannabinoid drug still under study in the US. It’s a mouth spray made up of a whole-plant extract with THC and cannabidiol (CBD) in an almost one to one mix. It’s available in Canada and parts of Europe to treat pain linked to cancer, as well as muscle spasms and pain from multiple sclerosis (MS). It’s not approved in the US at this time, but it’s being tested in clinical trials to see if it can help a number of conditions.

How can cannabinoid drugs affect symptoms of cancer?

Based on a number of studies, dronabinol can be helpful for reducing nausea and vomiting linked to chemotherapy.

Dronabinol has also been found to help improve food intake and prevent weight loss in patients with HIV. In studies of cancer patients, though, it wasn’t better than placebo or another drug (megestrol acetate).

Nabiximols has shown promise for helping people with cancer pain that’s unrelieved by strong pain medicines, but it hasn’t been found to be helpful in every study done. Research is still being done on this drug.

Side effects of cannabinoid drugs

Like many other drugs, the prescription cannabinoids, dronabinol and nabilone, can cause side effects and complications.

Some people have trouble with increased heart rate, decreased blood pressure (especially when standing up), dizziness or lightheadedness, and fainting. These drugs can cause drowsiness as well as mood changes or a feeling of being “high” that some people find uncomfortable. They can also worsen depression, mania, or other mental illness. Some patients taking nabilone in studies reported hallucinations. The drugs may increase some effects of sedatives, sleeping pills, or alcohol, such as sleepiness and poor coordination. Patients have also reported problems with dry mouth and trouble with recent memory.

Older patients may have more problems with side effects and are usually started on lower doses.

People who have had emotional illnesses, paranoia, or hallucinations may find their symptoms are worse when taking cannabinoid drugs.

Talk to your doctor about what you should expect when taking one of these drugs. It’s a good idea to have someone with you when you first start taking one of these drugs and after any dose changes.

What does the American Cancer Society say about the use of marijuana in people with cancer?

The American Cancer Society supports the need for more scientific research on cannabinoids for cancer patients, and recognizes the need for better and more effective therapies that can overcome the often debilitating side effects of cancer and its treatment. The Society also believes that the classification of marijuana as a Schedule I controlled substance by the US Drug Enforcement Administration imposes numerous conditions on researchers and deters scientific study of cannabinoids. Federal officials should examine options consistent with federal law for enabling more scientific study on marijuana.

Medical decisions about pain and symptom management should be made between the patient and their doctor, balancing evidence of benefit and harm to the patient, the patient’s preferences and values, and any laws and regulations that may apply.

The American Cancer Society Cancer Action Network (ACS CAN), the Society’s advocacy affiliate, has not taken a position on legalization of marijuana for medical purposes because of the need for more scientific research on marijuana’s potential benefits and harms. However, ACS CAN opposes the smoking or vaping of marijuana and other cannabinoids in public places because the carcinogens in marijuana smoke pose numerous health hazards to the patient and others in the patient’s presence.

CBD Gummies For Cancer

The cannabis plant contains hundred of compounds, some of which are cannabinoids. CBD (cannabidiol) is the second most prevalent cannabinoid – after tetrahydrocannabinol (THC) – and is usually extracted from hemp, a strain of the Cannabis sativa plant that contains a high percentage of CBD. 1 The medical community has been aware of CBD for many years now, however, it was not until the discovery of the endocannabinoid system (ECS) in humans in the late 1980s that its potential as a therapeutic ingredient was explored. The ECS is a complex cell-signaling system found throughout the body that is thought to regulate a number of important physiological functions, like sleep, mood, cognition and pain perception. 2,3 Unlike THC, CBD has no psychoactive ‘high’ effects, making it an attractive therapeutic option for multiple health areas, including cancer.

CBD and cancer: What do we know so far?

Cancer is a complex disease, influenced by genetics, as well as environmental and lifestyle factors. As such, cancer remains difficult to treat and, despite improvements in medical care, patients with cancer still experience many unwanted and distressing symptoms. However, advances in cancer care are continuously made, with new treatment approaches being explored all the time. Take CBD for example. The use of cannabinoids, including CBD, for the treatment of cancer has been of interest to the scientific community for some time. It is thought that CBD may help cancer patients manage some of the symptoms of the disease, and side effects of treatment. At the same time, researchers in the field are looking into whether CBD could slow or stop cancer altogether. So, what do we know so far?

    A promising anti-cancer drug
    There are a number of pre-clinical in-vitro and in-vivo studies that suggest cannabinoids – including CBD and THC – have anti-cancer activity in a wide variety of cancer types, including a role in cancer cell death and blocking cancer cell growth. For example, the potential of CBD in breast cancer has been studied for many years, showing consistent and effective pro-apoptotic and anti-proliferative activity in many different breast cancer cells and mouse models. 4 This is significant since breast cancer is the number one leading cause of new cancer cases and the second leading cause of cancer deaths of women in the US, and new advancements in the field are therefore always welcomed. 5 Similar effects have been demonstrated in multiple other cancer types too, including glioma (the most common primary brain malignancy), pancreas, prostate, colorectal and lymphoma. 6,7,8,9

But that’s not the only anti-cancer activity CBD is hypothesized to have. As well as acting on cancer cells directly, it has been suggested that CBD affects the tumor environment too by stopping the development of blood cells that feed the cancer, preventing its ability to spread and reducing inflammation. 10,11 Furthermore, despite its activity against cancer cells, CBD – alone or together with THC – appears to have a milder effect (or no effect at all) on normal cells in the same tissues or organ as the cancer itself, making it an attractive anti-cancer therapeutic. 12,13,14

Unlock the potential of CBD with DSM

Interest is building rapidly in the CBD space, and increasing attention is being given to its potential benefits in cancer patients. There is solid evidence supporting the idea that cannabinoids, like CBD, demonstrated anti-cancer activity in cultured cancer cell lines and animal models. 4 In addition, CBD is thought to have potential as a complementary treatment of cancer, where it may help to relieve common cancer-related or cancer-therapy symptoms. However, there is not enough evidence to fully support the use of CBD in cancer just yet. In order to progress research in this field further and advance the development of CBD as a cancer treatment, there is an urgent need for more large-scale and well-designed clinical trials in humans to determine the role and efficacy of CBD in a variety of cancer types.

To help customers realize the full potential of CBD – and inspire the creation of bespoke, purpose-led drug products – DSM has created a platform that facilitates early-stage drug development and novel scientific discoveries in the rapidly evolving CBD space.

Cannabis, CBD oil and cancer

Cannabis is a plant and a class B drug. It affects people differently. It can make you feel relaxed and chilled. But it can also make you:

  • feel sick
  • affect your memory
  • make you feel lethargic

CBD oil is a chemical found in cannabis.

Summary:

  • Cannabis has been used for centuries recreationally and as a medicine.
  • It is illegal to possess or supply cannabis as it is a class B drug in the UK.
  • Research is looking at the substances in cannabis to see if it might help treat cancer.
  • There are anti sickness medicines that contain man-made substances of cannabis.

What are cannabis and cannabinoids?

Cannabis is a plant. It is known by many names including:

The plant produces a resin that contains several substances or chemicals. These are called cannabinoids. Cannabinoids can have medicinal effects on the body.
The main cannabinoids are:

  • Delta-9-tetrahydrocannabinol (THC)
  • Cannabidiol (CBD)

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.

CBD is a cannabinoid that may relieve pain, lower inflammation and decrease anxiety without the psychoactive ‘high’ effect of THC.

Different types of cannabis have differing amounts of these and other chemicals in them. This means they can have different effects on the body.

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

CBD oil, cannabis oil and hemp oil

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.

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.

Cannabis oil comes from the flowers, leaves and stalks of the cannabis plant. Cannabis oil often contains high levels of the psychoactive ingredient THC. Cannabis oil is illegal in the UK.

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.

Why people with cancer use it

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

There has been a lot of interest into whether cannabinoids might be useful as a cancer treatment. The scientific research done so far has been laboratory research, with mixed results, so we do not know if cannabinoids can treat cancer in people.

Results have shown that different cannabinoids can:

  • cause cell death
  • block cell growth
  • stop the development of blood vessels – needed for tumours to grow
  • reduce inflammation
  • reduce the ability of cancers to spread

Scientists also discovered that cannabinoids can:

  • sometimes encourage cancer cells to grow
  • cause damage to blood vessels

Cannabinoids have helped with sickness and pain in some people.

Medical cannabis

This means a cannabis based product used to relieve symptoms.

Some cannabis based products are available on prescription as medicinal cannabis. The following medicines are sometimes prescribed to help relieve symptoms.

Nabilone (Cesamet)

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.

Sativex (Nabiximols)

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.

Researchers are looking into Sativex as a treatment for cancer related symptoms and for certain types of cancer.

How you have it

Cannabis products can be:

  • smoked
  • vaporized
  • ingested (eating or drinking)
  • absorbed through the skin from a patch
  • applied as a cream
  • applied as a spray

CBD oil comes as a liquid or in capsules.

Side effects

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

  • increased heart rate
  • blood pressure problems
  • drowsiness
  • dizziness
  • mood changes
  • memory problems

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

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.

Research into cannabinoids and cancer

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

Clinical trials need to be done in large numbers where some patients have the drug and some don’t. Then you can compare how well the treatment works.

Many of the studies done so far have been small and in the laboratory. There have been a few studies involving people with cancer.

Sativex and temozolomide for a brain tumour (glioblastoma) that has come back

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.

Researchers found that adding Sativex caused side effects, which included, vomiting, dizziness, fatigue, nausea and headache but patients found the side effects manageable.

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.

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.

Researchers have now started a larger phase 2 trial called ARISTOCRAT, to find out if this treatment is effective and who might benefit from it. Speak to your specialist if you want to take part in a clinical trial.

Sativex and cancer pain

There are trials looking at whether Sativex can help with cancer pain that has not responded to other painkillers.

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.

Cancer and nausea and vomiting

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

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.

Other research

A drug called dexanabinol which is a man-made form of a chemical similar to that found in cannabis has been trialled in a phase 1 trial. This is an early trial that tries to work out:

  • whether the drug works in humans
  • what the correct dose is
  • what the side effects might be

The results are not available yet. You can read about the trial on our clinical trials database.

Word of caution

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

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.

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.
