    The administration of THC reduces the tumor growth of metastatic breast cancer and “might constitute a new therapeutic tool for the treatment” of cancerous tumors, according to preclinical data published online in the journal Molecular Cancer.

    Investigators from Complutense University in Madrid assessed the anti-tumor potential of THC and JWH-133, a non-psychotropic CB2 receptor-selective agonist, in the treatment of ErbB2-positive breast tumors – a highly aggressive form of breast cancer that is typically unresponsive to standard therapies.

    Researchers reported, “[B]oth Delta-9-tetrahydrocannabinol … and JWH-133 …reduce tumor growth [and] tumor number [in mice]. … [T]hese results provide a strong preclinical evidence for the use of cannabinoid-based therapies for the management of ErbB2-positive breast cancer.”

    In 2007, investigators at the California Pacific Medical Center Research Institute reported that the administration of the nonpsychoactive cannabinoid CBD limited breast cancer metastasis in a manner that was superior to comparable synthesized agents.

    Previous preclinical studies assessing the anticancer properties of cannabinoids have shown that they inhibit the proliferation of a wide range of cancers, including brain cancer, prostate cancer, oral cancers, lung cancer, skin cancer, pancreatic cancer, biliary tract cancers, and lymphoma.

    Full text of the study, “Cannabinoids reduce ErbB2-driven breast cancer progression through Akt inhibition,” is available online here.

      Thanks NORML – Why doesnt the president of our country want to help its people? HUH? He acted all cool and open to the subject and has Done some good (they still don’t listen to him).Does president Obama know that the cannabis plant fights cancer? Is he behind hiding this from the world also?!Just like the others-we are one —–WHY?

      JWH-133 shown to reduce tumor growth?

      Must be why the State of Illinois just banned JWH-018 and JWH-073. Imagine how much money Pharma would loose if a whole generation dodged the cancer bullet!!

    5. […] has been shown to reduce the growth of cancer cells in mice in a recent study out of Madrid, Spain, according to NORML. Investigators from Complutense University in Madrid assessed the anti-tumor potential of THC and […]

      Most people know why MJ isn’t at the forefront of modern medicine. It’s not because it doesn’t have extraordinary medical properties, it’s because of 1) Greed, 2) Ignorance, & 3) Predjudice.

      So far, the absolute worst debate points I’ve encountered is that it smells bad and he doesn’t want to have to run a gauntlet of people smoking pot outside buildings as he now has to do with cigarette smokers… In his mind – just keep it illegal forever!

      I still say, and I will say it every day till someone lisens.

      There has to be a dirrect corrilation between the prohibition of canabis in the early 1900’s and the spike in the cancer rate since then.

      maybe that is why it is illeagle because it can help.
      seems thay do not want people to get better.
      i know myself i smoked a many years with no problerms but when i start with cigaretts after a while coughing , flemm, cant dance as long. just to mentiom a few things,
      dont forget some doctors own chemo thnig.s they aare not willing to loose money. that is another horror story.
      bless you all be happy

    9. Mike Stroup says:

      Depriving people of the medical benefits of cannabis will be another charge against prohibitionists when justice is served and they are rightfully held to account for all their drug “war” crimes.

    10. claygooding says:

      One chemo therapy treatment costs $40 thousand dollars or
      more and most patients require five or six treatments.
      So you think the pharmaceutical companies want a cancer blocking and treatment medicine growing in your yard?
