In January of this year, the National Cancer Institute updated its Cannabis and Cannabinoids PDQ® webpage with the following new cannabis and cancer information, which just by coincidence supports the new GW Pharma pre-approved patent and lays the groundwork for GW Pharma’s future new breakout marijuana-based cancer drugs.

“This invention relates to the use of phytocannabinoids, either in an isolated form or in the form of a botanical drug substance in the treatment of cancer. Preferably the cancer to be treated is cancer of the prostate, cancer of the breast or cancer of the colon,” according to the patent application.

All phytocannabinoids? As in the plural? As in covering every chemical this plant makes and its use in the treatment of human cancer?

“Researchers however have discovered that some cannabinoids, including THC and cannabidiol (CBD) are able to promote the re-emergence of apoptosis (the signal for a cell to die) so that some tumors will heed the signals, stop dividing, and die.”

“Another method by which tumors grow is by ensuring that they are nourished: they send out signals to promote angiogenesis, the growth of new blood vessels. Cannabinoids may turn off these signals as well.

“In summary these data demonstrate the protective effects of phytocannabinoids in the PREVENTION of colon cancer. Of significance is the phytocannabinoids CBG which exerts a strong protective effect against colon cancer particularly when it is in an isolated form.”United States Patent Application # 20130059018 Assignee: GW Pharma

This patent was pre-approved and was written to only include cannabis products made by GW Pharma.
