Big Pharma Will Now Hold Patent for CBD/THC Cancer Treatment

It’s hard to believe that Big Pharma is the one making the most progress in proving that cannabis works! Well, maybe not so much ‘hard to believe’ as disheartening and depressing as heck.

British company, GW Pharmaceuticals, has been a big name in cannabis pharmaceuticals since 1998. They’ve broken through the iron gates surrounding cannabis medicine, so much so that they even got CBD-extract medications (made by Big Pharma) to be removed from Schedule I.

GW Pharma has developed cannabis-based drugs for multiple sclerosis and epilepsy, and now….cancer. That’s right. Big Pharma now holds the patent for cancer treatment using cannabis. Let. That. Sink. In. For. A. Moment.

In 2009, GW went forward with a patent application, alongside collaborator Otsuka Pharmaceutical.  At the end of September, GW  announced that they had received a Notice of Allowance from the U.S. Patent Office to go forward with production of their cannabis-based cancer treatment, Sativex.

The Treatment

Numerous studies have shown that cannabis can be used to treat cancer by eradicating cancer cells and stopping metastasis, in most types of cancer. The latest GW drug will harness the power of THC and CBD to treat gliomas, which are a rare form of brain cancer.

The now-patented pharmaceutical uses a ratio of THC and CBD ranging from 1:1 to 1:20 (THC:CBD) to “reduce cell viability, inhibit cell growth or reduce tumor volume”, according to the company. It is interesting to note that GW’s treatment, Sativex, grew out of a long history of pre-clinical trials and anecdotal evidence that show the use of cannabis and cannabis-based products for tumor reduction.

The company went ahead with clinical trials in August 2018 to test the efficacy of Sativex. This trial will look at efficacy of Sativex when combined with more traditional mainstream cancer treatments. Sativex and the chemotherapy drug, temozolomide, has been administered to 20 patients with recurrent glioblastoma multiforme (GBM). This is a rare and very deadly type of brain cancer.

The Patent

The original patent application was sent in 2009, but has been subsequently changed to accommodate FDA requirements. Changes would include specifics like THC and CBD ratios in the medication, as well as the forms of cancer that Sativex may be able to treat.

What Does This Mean for Cancer Research?

On the positive side, the patent recognizes the value of cannabis for cancer treatments, and not just as a way to counteract the effects of chemotherapy and radiation. Cannabis’ efficacy for killing cancer cells must now be recognized on a federal level. This also allows for more options for cancer patients in choosing their treatments.

It’s a potentially exciting time for cannabis research! Look out for more patents, more clinical trials, and even more cannabis-based medications hitting the market. Keep pushing for access to whole plant medicine.

    They will let us have it for cancer when they can tie it up so that it costs the patients tens and thousands of dollars. They will also have to reduce the effectiveness tremendously and use doubletalk to excuse that.

    It’s about time people were allowed to treat themselves, after all it was the public that has used it for years, now they’re trying to to charge us for curing ourselves.
    This is what is wrong with the idiots in power

    It’s true that in 2009, GW & Otsuka Pharmaceuticals moved forward on the patent. Last September, they were indeed granted a Notice of Allowance from the U.S. Patent Office “to go forward” with production of their cannabis-based cancer treatment called “Sativex”. It’s also true that GW’s patented cancer treatment uses ratios of THC and CBD from 1:1 to 1:20 (THC:CBD) to “reduce cell viability, inhibit cell growth or reduce tumor volume”.

    So why do oncologists continue to kill people with deadly poisons before trying natural or (now patented) pharmaceutical alternatives? Because of ignorance and greed; that’s why. Thanks to all who work hard to change that. We’re getting there.

      This site details what Dr. Robert Melamede describes as an extreme example of a successful (cannabis-driven) metabolic approach to cancer treatment.

      “The patient shows a multi-phenotypic reversal, in I year, by cannabis extracts of the genetic deficiency Xeroderma pigmentosum) that cause cancers. The cannabis-based treatment protocol
      eliminated pain and depression, while healing melanoma on the scalp, as well as tongue
      and lip cancers. Additionally, sight was restored”.

      See “In G.O.D. We Rust-The Beauty of UnIntelligent Design” by Dr. Bob here:

    Aloha. We the people want, need, deserve and some of us demand a First Amendment solution for full and free access to God given Cannabis in our homes and gardens. The concept of “separation of church and state” fills the need for securing home sanctuaries all over the U.S.A. with zero regulations, permit, or license needed. Equal justice under law requires that home-brew laws apply equally to home grows of Cannabis that’s not in commerce.

    Cannabis hemp is a natural, God given, seed-bearing plant, not an artificial, man-made drug. Government has no – rightful – jurisdiction to prohibit it from us. Full and free access to Cannabis and all the other seed-bearing plants is part of our inheritance as Homo Sapiens born on planet Earth. Let freedom ring! Thank you.

    Although I didn’t see how much they are charging for their miracle cure, I’m guessing that it’s more than a bag of good weed.

    No surprise at this since they own and operate even our patient offices too. Yes we are the step children of the British government. They have been using us like a throw rug to build their crumbling empire since the 1800’s . I bet they get a kick out of our land of the free and home of the brave motto. Well thanks be to heaven the truth of these sick parasites is being exposed to the mass slaves they thought would remain stupid forever. The naked truth is going to kick them is their sorry ass and then they will know its pay back time and hell knows no fury like a freed people with a axe to grind.
    Read the book scum balls you lose it all. Your ship is sunk!!!
