Cannabis Once Again Shown To Halt Cancer Growth — So Why Aren’t We Studying It In Humans?

    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.

      Just another reason it should be legal

    2. Alex says:

      Brilliant

    3. Jed The head says:

      After reading this you have to wonder how much further the research would be if studies would have been allowed for the past 70 years. Thanks NORML for the information.

    4. ck30 says:

      Those are all reasons to just legalize ACROSS THE BOARD people these days WANT to live longer

      So why aren’t we doing studies in humans,maybe it’s because the cancer researchers are working for big Drug companies that have loads of money already tied up in synthetic products already in the pipelines for development. Why is the question, would someone please give me the answer,not any kind of theory,but the answer as to why such an advanced nation can’t get it done right.Why do we continue to throw money down the black hole known as the drug war,why does this nation think that killing more Mexicans,and throwing more peace loving hard working American citizens in jail is in anyone’s best interest.I just don’t get it man.A substance that shows greater promise than any substance ever in history,and it is flat out IGNORED. I don’t get it man,I really just don’t understand.Millions and millions is spent annually on cancer research,with very little to show for it.Millions and millions of people suffering and dieing of cancer daily,you would figure that a substance that shows so much promise would be the top chemical on every researchers list.I don’t get it, I just don’t understand

      Why ? Money. Thats always it.

    7. JohneyReeferSeed says:

      Even if they flat out had proof that Cannabis cures Cancer it still would be struck down by the feds. The federal government is not doing what the people want and that is why this November the PEOPLE will decided whats best for ourselves!

    8. Travis Clark says:

      We aren’t testing it on humans because it’s probably good medicine. Might compete with chemical/radioactive cocktail sales. Maybe we’ll try it out once Monsanto gets around to trowing in an octopus gene.

    9. Joel: the other Joel says:

      The marijuana prohibitionist would still say, “marijuana has no medical value”, because it is written in the Control Substance Act of 1970. That law is unconstitutional because it was created by the late former President Nixon’s own personal hatred toward marijuana. He wants to outlaw it to the highest degree!
      Why?

    10. Spook says:

      what the fuck does it have 2 do??? bring the dead back 2 life before the feds legelize???
