Medical Marijuana and Cancer

Cancer has touched the lives of almost every person living in the U.S. today. When you find out you have cancer, it’s an incredible shock to your system. Thankfully, there are new treatments and ways of managing the disease coming out on a regular basis. If you’re struggling with cancer treatment or you know someone who is, it’s likely that you’ve wondered about taking medical cannabis for cancer to ease your symptoms.

Millions of Americans are afflicted with cancer, the nation's second-leading cause of death. There are more than 100 types of cancer, including breast cancer, skin cancer, lung cancer, colon cancer, prostate cancer and lymphoma. Treatment options for cancer include surgery, chemotherapy and radiation therapy, which are often harsh and cause severe side effects.

types of cancer

Studies spanning more than three decades show that medical marijuana is an effective treatment for symptoms of cancer as well as the side effects of chemotherapy and radiation therapy. THC — the main chemical component in marijuana — is a natural antiemetic, which has been shown to help decrease the pain associated with many types of cancer and chemotherapy agents. THC can also help battle chemotherapy-induced nausea and vomiting (CINV).

What’s more, recent research has shown that medical marijuana has cancer-fighting properties. According to more than 18 major studies published between 2001 and 2003, cannabinoids have a significant effect fighting cancer cells and have also been shown to exhibit anti-tumor properties.

Here, we’ll look at what cancer is, how medical marijuana for cancer is an effective treatment, the best strains to use and much more.

What Is Cancer?

Everyone has heard the word, but do you know what this disease is? Cancer begins in the building blocks of your body – your cells. In a healthy individual, your body creates new cells when you need them, replacing old ones that have died off. In a person with cancer, this process goes wrong. Even when your body doesn’t need them, new cells grow and old ones continue to live when they shouldn’t.

These extra cells can create a mass that is known as a tumor. Tumors can be benign — non-cancerous — or malignant — cancerous. When you have a malignant tumor, its cells can invade your healthy tissue nearby and can sometimes break away and spread to other areas of your body.

Cancer is a general term frequently used to indicate any of various types of malignant neoplasms, most of which invade surrounding tissues, may metastasize to several sites and are likely to recur after attempted removal and to kill the patient unless adequately treated.

When we speak of cancer, we aren’t simply talking about one disease, but many. In fact, there are more than 100 different types of cancer, and each type has its own set of characteristics. The majority of cancers are named after where they begin, even if they have spread from the primary site. For example, cancer that starts in the lungs is called lung cancer. Cancer that started in the breasts but spread to the lungs is called metastatic breast cancer.

When cancer spreads to a different area of your body, this is known as metastasis. The treatment you receive and symptoms you present with depend both on the type of cancer you have and how advanced the illness is.

The History of Cancer

You may think of cancer as a modern-day illness. However, the earliest evidence of the disease is found in the fossilized tumors of ancient Egyptian mummies. The name “cancer” was not used in those times. There are texts dating back to approximately 3000 B.C. that describe the disease. Edwin Smith Papyrus indicates that although there was no known treatment for cancer in ancient Egypt, at least eight ulcers or tumors of the breast were treated by cauterization.

Hippocrates (460-370 B.C.), known as the “Father of Medicine,” was the first person to use the word carcinos to describe non-ulcer forming and carcinoma to name ulcer-forming tumors. The ancient Greek physician used these words as in Greek they mean “crab.” He called them this due to the projections that spread out from cancer, in a similar shape to a crab.

Regarding treatment, cancer surgeries became widespread in the 19th and early 20th centuries, coming after the development of anesthesia, with other treatments including radiation therapy, chemotherapy, immunotherapy and hormone therapy. Now, of course, medical marijuana is being used in the treatment of cancer.

Cancer Symptoms

As there are many different types of cancer, indicators often vary. Here, we look at some of the most common symptoms. Keep in mind that having any of these symptoms or signs does not mean you necessarily have the disease. Many other illnesses and conditions can cause these issues, too. If you’re at all worried about any of the following, please get in touch with your doctor.

Symptoms of cancer may include:

  • Fatigue. Patients explain this as extreme tiredness and exhaustion that doesn’t improve with rest.
  • Fever. This usually occurs when the disease is affecting your immune system.
  • Unexplained weight loss. A sudden and unexplained significant weight loss of ten pounds or more could be a sign of cancer.
  • Pain. Pain that doesn’t go away can be an early symptom of some cancers.

Signs of cancer may include:

  • Skin changes. Yellowish eyes or skin, darker looking skin, itching, reddened skin or excessive hair growth can be a warning sign.
  • Change in bowel habits or bladder function. Changes in these functions can be a symptom of prostate, bladder or colon cancer.
  • Skin sores that don’t heal. This can be a sign of skin cancer or oral cancer.
  • White patches in the mouth or white spots on the tongue. These can be a precancerous indication that can become mouth cancer.
  • Unusual bleeding or discharge. A medical doctor should investigate any unusual bleeding or discharge.
  • Skin changes. Bleeding moles or ones that change in size could be an indication of skin cancer.
  • Trouble swallowing or indigestion. These could be signs of cancers of the throat, stomach or esophagus
  • Lumps or thickening of body tissue. These are potential signs of a tumor.

There are many different cancer symptoms and signs. You know your body best. If something doesn’t seem right, seek medical attention as soon as you can.

The Effects of Cancer

As all cancers are different, some can be treated fairly rapidly, whereas others take time and cause discomfort. Cancer not only affects you as an individual, but it also reaches your family and friends, too. It’s crucial to have the best quality of life you possibly can while you’re fighting the disease. Gentle and effective treatments, like marijuana/cannabis for cancer, for example, can contribute to a better quality of life.

Cancer Statistics

According to information from the National Cancer Institute:

  • 14.5 million people in 2014 lived beyond their cancer diagnosis. This is expected to rise to as many as 19 million by 2024.
  • U.S. national expenditures for cancer care were almost $125 billion in 2010 and are projected to be as much as $156 billion by 2020.
  • The number of newly diagnosed cases of the disease will increase by approximately 22 million within the next twenty years.
  • The number of new cases of cancer per year, based on the years 2008 to 2012, is 454.8 per 100,000 males and females each year.

Medical Treatments for Cancer and Their Side Effects

There are several intensive treatments for cancer, with three of the most common being surgery, radiation therapy and chemotherapy. Here is some additional information on each of these three most common types of treatments.

Surgery

Surgery is one of the oldest forms of cancer treatment. Not only is it used to remove cancerous tumors and tissue, but it’s also used to diagnose the disease and determine how far it may have spread. All medical procedures have risks, of course, but the risks with surgery can be particularly high.

Complications could arise from the surgery and the types of medications used. The more invasive the procedure, the higher the risk. Side effects include tissue damage, reactions to drugs, blood clots, bleeding, severe pain, infections and several others.

Radiation Therapy

This form of treatment uses waves or particles of concentrated energy to either damage cancer cells or destroy them completely. It is also a common method of treating the disease and has potentially severe side effects. Fatigue is one of the most common side effects, as is hair loss. Some patients lose the hair on their head, as well as eyebrows and eyelashes. The loss can be permanent. In some instances, when hair returns, it is either a different texture than before or substantially thinner.

Chemotherapy

Chemotherapy drugs are designed to kill fast-growing cancer cells. Unfortunately, because the drugs travel throughout the body, they often damage healthy, normal cells as well. Bone marrow cells that play an important role in forming blood, hair follicles and cells in the digestive tract, reproductive system and mouth are among those most commonly affected. Chemotherapy drugs can also lead to problems affecting the nervous system, kidneys, lungs, bladder and heart.

Besides surgery, radiation therapy and chemotherapy, there are other methods to treat cancer, which are listed in the table below. The treatment you’ll receive depends on the type of cancer you have and how advanced it is.

How Marijuana Is an Effective Treatment for Cancer

Marijuana is the name for the dried leaves and buds of the Cannabis sativa plant. Alternative names for the substance are ganja, marihuana, hemp, weed, hash, grass, pot and more. The plant has been used in herbal remedies for centuries. Marijuana has biologically active cannabinoids, many of which have a therapeutic effect on your body. Scientists have identified THC and CBD in particular. In fact, Dronabinol, a pharmaceutical form of THC and a manmade cannabinoid medication, and Nabilone have both been approved by the FDA for the treatment of some conditions.

In Canada, Nabiximols/Sativex, which contains both THC and CBD, is approved for the relief of pain in people with multiple sclerosis and advanced cancer.

endocannabinoids

The active cannabinoids in the plant mimic your internal endocannabinoid system (ECS). Your body’s endocannabinoids are responsible for keeping your critical biological functions — for example, pain, immune system, appetite and sleep in balance. When your body is out of balance and in a state of stress, your endocannabinoids work to correct this imbalance. The endocannabinoids in the plant enable your body to restore its sense of balance, which is one of the reasons cannabis works so well for you if you have cancer.

Marijuana and Cancer: Clinical Evidence and Research

The incidence of cancer in the general population has steadily increased along with accelerating advancements in medical technology. As people live longer, the ability for cells to faithfully copy their DNA is diminished resulting in mutations in somatic cells — everything excluding the sperm and ovum. Current research has shown that possible benefits of using medical marijuana to treat cancer and related conditions are evident in the prevention of the spread of tumors throughout the body and in alleviating the side effects associated with chemotherapy and other aggressive drug therapy.

Some scientific studies have looked at cannabis as an effective anti-cancer treatment with promising results. Individual components of the cannabis plant, for example, may be able to help stop the growth of several types of cancer tumors, such as those found in liver, breast, brain and other types of cancer. They have also shown promise in helping to stimulate the death of tumor cells, a process known as apoptosis.

According to information from the National Cancer Institute:

  • Studies in rats and mice have shown that cannabinoids may prevent cell growth and block the development of blood vessels that are needed by tumors to grow. They may also inhibit the growth of tumors by causing cell death.
  • Animal and laboratory studies have shown that cannabinoids may kill cancer cells while protecting your healthy cells.
  • Studies have shown that cannabinoids may help prevent and treat colon cancer, liver cancer, breast cancer and non-small cell lung cancer.
  • Multiple studies in animals have illustrated that cannabinoids can stimulate appetite.
  • Animal studies have indicated that cannabinoids could prevent nerve problems that result from chemotherapy.

There are also some studies currently in progress investigating the effects of marijuana on the following:

  • Treating graft vs. host disease in people who’ve undergone stem cell transplants with CBD.
  • Treating recurrent glioblastoma multiforme with an oral spray containing CBD/THC.
  • Treating solid tumors with an oral form of CBD.

Although research is promising, so far it’s been limited to “preclinical” studies, which involve testing treatments or drugs in animals before they are used on humans. This preclinical research is offering hope to many cancer patients, but a great deal more is needed. More rigorous studies must be conducted.

For that to happen, the federal government will have to loosen the restrictions on medical marijuana research. Even though the National Cancer Institute — a program that runs on federal funds — has acknowledged that cannabis has shown the ability to kill cancer cells, the government still refuses to help researchers conduct more extensive studies into how marijuana may be able to help people fighting the disease.

Cancer and Marijuana Cannabinoids

The active molecular components in marijuana, known as the cannabinoids, are known to have neuroprotective and analgesic, or pain-relief, effects. Delta-9-tetrahydrocannabinol, or THC, is the cannabinoid that many cannabis researchers have focused on in the past several decades of studies of marijuana and cancer-related ailments. However, many medical marijuana patients and physicians believe that the purified form of THC or its synthetic counterparts are not as effective as orally consuming foods, referred to as edibles, or liquids, called tinctures, made with cannabis, or the smoking of the buds on the marijuana plant. It is possible that the marijuana plant’s multitude of different natural cannabinoids provides an increased therapeutic effect as opposed to a single synthetic cannabinoid.

Cannabinoids have also been researched for their possible use in cancer prevention and cancer treatment. Cancer is most notably defined by the multiplication of mutated somatic cells in the body. The mutated cells have damaged DNA that was not copied correctly during cell division. Cancer cells multiply more rapidly than normal cells and often have altered functions due to the cells’ mutated genetic code.

Cannabinoids have been proven to stimulate the apoptotic pathway in cells, which is the programmed death of a cell that has acknowledged that it is no longer functioning efficiently. In this way, marijuana can actively prevent tumor growth by signaling cancerous cells to “commit suicide.” Also, the cannabinoid receptors arrest the Growth 1, or G1, phase of the cell cycle. This ultimately prevents the cancer cell from maturing any further, which would inhibit the number of harmful toxins created by the cancer cell.

The CB1 receptors also prevent inflammation in other parts of the body as an effect of the marijuana use with certain cancer patients suffering from inflammation. These were some of the first implications that suggested the cannabinoid receptors activated by marijuana and cancer could help prevent cancer cell inflammation and nerve pain associated with inflammatory response in cells.

Cancer and Marijuana Endocannabinoids

There are also endogenous, or human, forms of cannabinoids known as the endocannabinoids, which occur naturally in the brain and are responsible for activating the cannabinoid 1 and cannabinoid 2 receptors (CB1 and CB2). These are a group of G-coupled protein receptors located within the lipid membrane of cells found all over the body. Phytocannabinoids, which are the natural cannabinoids found exclusively in the resin-filled trichomes of the marijuana plant, activate these receptors.

Often, the cancer is so prevalent that patients must take more drastic measures to treat their illness. Chemotherapy is a comprehensive drug treatment that involves targeting mutagenic cancer cells and killing them with a regimented use of a variety of synthetic drugs. However, debilitating side effects such as decreased appetite — people under harsh chemotherapy treatments often suffer from malnutrition — and nausea often accompany the treatment.

The treatment can also harm healthy cells and considerably weakens the immune system of the patient. The cannabinoid receptors in marijuana have been shown to be effective in preventing nausea induced by anti-cancer treatments and in stimulating appetite. Cancer patients can thus smoke marijuana to prevent nausea and stimulate appetite and avoid the wasting-away that many suffer from.

What Cancer Symptoms Can Marijuana Treat?

The THC in marijuana is useful for relieving nausea and cancer pain and reducing inflammation. CBD helps to reduce anxiety and can help treat seizures. CBC can also lower inflammation and relieve pain. The National Cancer Institute states that marijuana can also:

  • Block cell growth.
  • Fight viruses.
  • Relieve muscle spasms.

Medical pot is also suitable for treating nausea and vomiting that’s related to some types of chemotherapy. Furthermore, it can be sleep inducing, so your body can try to repair itself while you rest.

Best Strains of Marijuana to Use for Cancer

If you live in a state where medical cannabis is legalized, the drug can significantly help manage your cancer symptoms. Different strains of cannabis are better for treating certain symptoms. Here, we look at some strains of marijuana that have helped cancer patients.

Every strain has its unique properties, and what might work for one person may not be right for you. Generally, some marijuana strains — sativa strains — are known to be euphoric or uplifting, while others — indica strains — are better-known for their sedative and calming effects.

Marijuana strains that are high in both CBD and THC tend to work in synergy to effectively relieve cancer pain. That being said, types that are high in either of these cannabinoids may also work for you. You may need to try out a few strains and dosages until you hit on the right one for your needs.

hybrid strain effectiveness

Marijuana strains that help relieve pain include:

  • ACDC. This is a non-psychoactive strain that makes you feel happy, uplifted, relaxed and focused.
  • Blackberry Kush. High in THC, Blackberry Kush is particularly known for its intense pain-relieving effects. It also makes you feel relaxed, sleepy and euphoric and is best taken at nighttime or on days you don’t have much to do.
  • Harlequin. Due to its CBD and THC content, Harlequin kills your pain while keeping you mentally alert. As such, this is a good option for daytime use.

Fatigue-reducing strains include:

  • Strawberry Cough. This fragrant strain makes you feel energized and boosted both physically and mentally.
  • Chocolope. Taking Chocolope when you’re wiped out enhances your focus and sensory awareness.
  • Pineapple Express. This feel-good strain has a tropical flavor of papaya, mango and pineapple and brings you abundant energy when you’re feeling weak.

Strains that help reduce depression include:

  • Pennywise. High in CBD, Pennywise gives you a clear head and relaxed mindset so you can think properly again.
  • Chernobyl. Lemon and lime scented, Chernobyl is perfect for you if you need to get out of your low mood quickly.
  • Super Silver Haze. This strain makes you feel creative and happy and contains strong citrus notes.

Appetite-stimulating strains include:

  • Bubba Kush. High in THC, this strain will relax you significantly while giving you a ravenous appetite.
  • Granddaddy Purple. Another high-THC strain, the grape- and berry-scented aroma will help you regain your appetite quickly.
  • Skywalker OG. Skywalker OG stimulates your appetite while not making you feel lethargic. It’s a good option for daytime use.

The following strains help prevent nausea:

  • Northern Lights. This potent strain calms your stomach while relaxing your body.
  • Blueberry Diesel. A great option if you need your stomach settled and your mood lifted.
  • Super Lemon Haze. If you have things to do, then this is the perfect strain for you. It calms your nausea while providing you with energy.

Best Methods of Marijuana Treatment to Use

The way cannabis affects you is dependent on how it enters your body. There are several options, including:

  • Vaporizing or smoking. When you inhale, the drug gets into your bloodstream and brain quickly. Therefore, the effects fade faster than pot that’s been taken by mouth.
  • Eating. When you take pot by mouth — for example, in baked goods — it can take hours for the drug to take effect.

No matter how you take medical pot, taking too much of a strain that’s high in THC can sometimes cause you to feel high. These symptoms should wear off quickly.

Marijuana and Cancer Federal Study

The Center for Medical Cannabis Research, an organization sanctioned by state and federal oversight committees, conducts research on the possible medical applications for marijuana/cannabis and cancer.

A recent double-blind controlled study of smoked placebo versus smoked marijuana in patients with cancer-derived chronic peripheral neuropathic pain found that 10 of the 16 patients they studied experienced a 30% reduction in pain after seven days of smoking cannabis. The study used a capsaicin-based pain model, meaning that the pain felt from the subjects was due to heat or a burning sensation. The study not only produced invaluable data on marijuana and cancer-induced pain, but it also paved a road to examining other ways in which cannabis can be used for analgesic effects.

The potential medical applications of the CB1 and CB2 receptors are growing exponentially, and the appeal of using something natural over synthetic pharmaceuticals is becoming more desirable by society. The endocannabinoid system is essential to the life and death cycle of cells, proving a link between marijuana and cancer’s central operating mechanism.

Cancer patients who benefit from the smoking of marijuana should not be denied the right to protect their life. The use of marijuana to treat cancer is a medical issue, to be discussed between a qualified doctor and their patient, not a legal one.
