Cannabis Kills Cancer, Multiple Studies Confirm

Cancer cells

According to a recent survey of over 900 cancer patients, less than 15% received information about medical marijuana from their physician or nurse – despite acknowledgement from the National Cancer Institute that cannabis treats a wide variety of disease symptoms and “has been shown to kill cancer cells.”

To fill in the gap, CannaMD covers the landmark studies that every cancer patient needs to know.

Marijuana and anti-tumor activity

In 1975, the Journal of the National Cancer Institute published a study that paved the way for modern marijuana research. After administering delta-9-tetrahydrocannabinol (THC) and cannabinol (CBN) – both marijuana compounds – to mice with Lewis lung adenocarcinoma, researchers noticed that tumor growth slowed and/or stopped. THC-treated mice showed prolonged survival rates, leading researchers to conclude:

“That [cannabis] compounds readily cross the blood-brain barrier and do not possess many of the toxic manifestations of presently used cytotoxic agents, makes them an appealing group of drugs to study.”

Twenty years later, another study found similar results: Mice and rats given various doses of THC exhibited a “significant” dose-related decrease in the incidence of hepatic adenoma tumors and hepatocellular carcinoma (the most common type of liver cancer), as well as a decrease in benign tumors in other organs.

Multiple studies have since observed the same trend with gliomas (one of the most malignant forms of cancer), lymphoblastic leukemia cells, and skin tumors.

How does cannabis kill cancer?

Research suggests cannabis may exert anti-cancer effects by causing cell death, modulating cell-signaling pathways, and inhibiting tumor invasion. For instance, a 2011 study of cannabidiol (CBD) – another marijuana compound – found that CBD kills breast cancer cells by inducing endoplasmic reticulum stress and inhibiting cell-signaling. Likewise, colon cancer studies show that CBD has a cancer-protective effect and reduces cell proliferation.

Perhaps most exciting, the National Cancer Institute notes that:

“Cannabinoids appear to kill tumor cells but do not affect their non-transformed counterparts and may even protect them from cell death.”

As Dr. Christina Sanchez explains in the video, below, this gives marijuana a unique advantage over chemotherapy. Instead of attacking all cells, cannabis only targets the dangerous ones – leaving healthy cells perfectly intact.

What cancer patients need to know

In addition to its disease-fighting properties, cannabis is also an effective treatment against cancer’s many symptoms, including:

  • Pain,
  • Nausea,
  • Loss of appetite,
  • Anxiety, and
  • Depression.

Countless patients, like breast cancer survivor Kate Murphy, notice almost immediate relief:

“[Marijuana] made me feel like I had an appetite for the first time in probably six months. Instead of lying around thinking about how sick I felt all the time (which was not my personality, which was very upsetting to my whole family), I was up and cooking, which was not anything I had done since I hadn’t felt well.”

  1. Hi, I have recently been using a hemp based CBD oil for treating my basil cell skin cancers. Does the cancer seem to look and feel worse befor it starts to show signs of getting better??? I have a ton of skin cancer and I’m praying that my topical will help. Do you think I need THC in the topical oil along with CBD???

    1. Hi Mary! Marijuana-derived CBD is quite different from hemp-derived CBD. We’d strongly recommend speaking with one of our physicians in more detail. Please feel free to give us a call at 1 (855) 420-9170. Looking forward to speaking soon!

      1. Marijuana-derived CBD is quite different from hemp-derived CBD.

        Thats a lot bull, the only difference is the amount of THC,

        1. That’s definitely a common perception; however, hemp and marijuana are actually different in more ways than one. Unlike marijuana, hemp plants adapt to most climates and require minimal care. Hemp is also used in manufacturing; whereas marijuana serves a primarily medicinal/recreational purpose. As popular hemp advocates, The Ministry of Hemp, explain:

          “Hemp is completely different from marijuana in its function, cultivation and application.”

          For more details, see: What Is Hemp and Why Does It Matter?.

          Likewise, hemp-derived CBD and marijuana-derived CBD are quite different, as well. While hemp oil has its benefits, researchers are quick to point out that marijuana-derived CBD, or cannabis oil, may be safer and more effective. According to Project CBD:

          “A huge amount of industrial hemp is required to extract a small amount of CBD. This raises the risk of contaminants as hemp is a bio-accumulator – meaning the plant naturally draws toxins from the soil.”

          Hemp oil also lacks critical medicinal terpenes and other secondary cannabinoids found in cannabis oil.

    2. You need to read about curaderm, or bec5. Loads of people have made videos compelled to share their success stories eliminating basal cell carcinomas. High strength cannabis extracts like Rick Simpson oil is the other go to. Cbd alone might not be enough.

    3. Yes Mary Jane you need THC not CBD. CBD is good for balancing psycho active ingredients, but not fighting cancer cells.

    4. The high THC : CBD high grade pure oils, as produced by the Rick Simpson Oil technique, has numerous documented cases — CBD alone in definitely not recommended for killing skin cancer. Please look up and read all the available information on RSO oil – v important.

  2. the video was very informative but they need to nix the loud background music, it is very distracting especially when the person talking has such an accent

    1. Please feel free to call our board-certified doctors at (855) 420-9170 to learn more about medical cannabis treatment and cancer.

  3. Good to know that a lot of medical professionals support this study. This is very informative. thank you very much for sharing this.

  4. Just received Florida Med Marijuana card for Smoldering Multiple Myeloma. Confused about ratio and % of CBD to THC for treatment.

    1. Hi Steve! We’re sorry to hear about your health struggles, but honored to help in any way we can. Please feel free to give our doctors a call at (855) 420-9170; we’re happy to talk through your question in more detail.
