Dr. Andrew Weil: Pot's Role in Cancer Treatment

By Paul Armentano


For nearly a decade now myself and others have been highlighting the potent anti-cancer and potentially cancer preventive properties of cannabinoids.

Now Dr. Andrew Weil, a best-selling author and world-renowned leader and pioneer in the field of integrative medicine, has lent his powerful voice to this discussion.

Research into possible medical uses of cannabis is enjoying a renaissance. In recent years, studies have shown potential for treating nausea, vomiting, premenstrual syndrome, insomnia, migraines, multiple sclerosis, spinal cord injuries, alcohol abuse, collagen-induced arthritis, asthma, atherosclerosis, bipolar disorder, depression, Huntington’s disease, Parkinson’s disease, sickle-cell disease, sleep apnea, Alzheimer’s disease and anorexia nervosa.

But perhaps most exciting, cannabinoids (chemical constituents of Cannabis, the best known being tetrahydrocannabinol or THC) may have a primary role in cancer treatment and prevention. A number of studies have shown that these compounds can inhibit tumor growth in laboratory animal models. In part, this is achieved by inhibiting angiogenesis, the formation of new blood vessels that tumors need in order to grow. What’s more, cannabinoids seem to kill tumor cells without affecting surrounding normal cells. If these findings hold true as research progresses, cannabinoids would demonstrate a huge advantage over conventional chemotherapy agents, which too often destroy normal cells as well as cancer cells.

As long ago as 1975, researchers reported that cannabinoids inhibited the growth of a certain type of lung cancer cell in test tubes and in mice. Since then, laboratory studies have shown that cannabinoids have effects against tumor cells from glioblastoma (a deadly type of brain cancer) as well as those from thyroid cancer¸ leukemia/lymphoma, and skin, uterus, breast, stomach, colorectal, pancreatic and prostate cancers.

… If you want to learn more about this subject, I recommend an excellent documentary film, “What If Cannabis Cured Cancer,” by Len Richmond, which summarizes the remarkable research findings of recent years. Most medical doctors are not aware of this information and its implications for cancer prevention and treatment. The film presents compelling evidence that our current policy on cannabis is counterproductive.

At this past weekend’s national NORML Conference, several panelists — myself included — discussed the use of cannabinoids as selective anti-cancer agents. We also screened Len Richmond’s excellent documentary (in which I’m briefly interviewed) “What If Cannabis Cured Cancer?” (Watch the movie trailer here.)

Fortunately, this important discussion is just now finally making its way into the mainstream. Unfortunately, it’s taken 30+ years to get the MSM to notice.

What possible advancements in the treatment of cancer may have been achieved over the past three decades had U.S. government officials chosen to advance — rather than suppress — clinical research into the anti-cancer effects of cannabis? It’s time for the public and the media to demand an answer.
