Study: Marijuana Could Stop Growth of Colon Cancer Cells

“The administration of the non-psychotropic cannabis plant constituent cannabidiol (CBD) is protective in an experimental model of colon cancer, according to preclinical trial data published online in the Journal of Molecular Medicine.

Investigators at the University of Naples assessed the effect of CBD on colon carcinogenesis in mice. Researchers reported that CBD administration was associated with cancerous tumor reduction and reduced cell proliferation.

Authors wrote: “Although cannabidiol has been shown to kill glioma cells, to inhibit cancer cell invasion and to reduce the growth of breast carcinoma and lung metastases in rodents, its effect on colon carcinogenesis has not been evaluated to date. This is an important omission, since colon cancer affects millions of individuals in Western countries. In the present study, we have shown that cannabidiol exerts (1) protective effects in an experimental model of colon cancer and (2) antiproliferative actions in colorectal carcinoma cells.”

Authors also acknowledged that CBD possesses “an extremely safe profile in humans.” They concluded, “[O]ur findings suggest that cannabidiol might be worthy of clinical consideration in colon cancer prevention.””

Cannabis and tobacco smoke are not equally carcinogenic

“Cannabis and tobacco smoke are not equally carcinogenic… Cannabis smoke contains cannabinoids whereas tobacco smoke contains nicotine (plus added carcinogens). Available scientific data, that examines the carcinogenic properties of inhaling smoke and its biological consequences, suggests reasons why tobacco smoke, but not cannabis smoke, may result in lung cancer… Furthermore, compounds found in cannabis have been shown to kill numerous cancer types including: lung cancer, breast and prostate, leukemia and lymphoma, glioma, skin cancer, and pheochromocytoma…”-

Cannabis Science Reports: National Cancer Institute Updates Confirm Successful Cancer Treatments with Medical Cannabis

“As we’ve previously reported, one of the most interesting findings that has emerged since the discovery of the endocannabinoid system (marijuana like compounds produced by humans, and all vertebrates) is that cannabinoids have profound cancer-killing and anti-metastatic properties.

There is strong scientific support, demonstrated in tissue culture and animal studies, of the potent cancer killing properties of cannabinoids for such deadly cancers as glioma, lung cancer, breast and prostate cancer, leukemias and lymphomas, and as well as skin cancers.”

“Cannabis Science, Inc. (OTCBB:CBIS), a pioneering US biotech company developing pharmaceutical cannabis products, is pleased to report a government released update on cancer treatments using medical cannabis (marijuana), updated March 17, 2011, summarizing how the treatment of cancer with cannabinoids goes beyond the simple treatment of symptoms and side effects by exhibiting possible direct antitumor activities.

This summary contains the following key information:

– Cannabis has been used for medicinal purposes for thousands of years prior to its current status as an illegal substance.

– Chemical components of Cannabis, called cannabinoids, activate specific receptors found throughout the body to produce pharmacologic effects, particularly in the central nervous system and the immune system.

– Cannabinoids may have benefits in the treatment of cancer-related side effects.

– The potential benefits of medicinal Cannabis for people living with cancer include antiemetic effects, appetite stimulation, pain relief, and improved sleep.

– Though no relevant surveys of practice patterns exist, it appears that physicians caring for cancer patients who prescribe medicinal Cannabis predominantly do so for symptom management.

– Unlike other commonly used drugs, cannabinoids are stored in adipose tissue and excreted at a low rate (half-life 1-3 days).

– Even abrupt cessation of cannabinoid intake is not associated with rapid declines in plasma concentrations that would precipitate severe or abrupt withdrawal symptoms or drug cravings.

Robert Melamede, Ph.D., Cannabis Science’s CEO stated, “As we’ve previously reported, one of the most interesting findings that has emerged since the discovery of the endocannabinoid system (marijuana like compounds produced by humans, and all vertebrates) is that cannabinoids have profound cancer-killing and anti-metastatic properties. There is strong scientific support, demonstrated in tissue culture and animal studies, of the potent cancer killing properties of cannabinoids for such deadly cancers as glioma, lung cancer, breast and prostate cancer, leukemias and lymphomas, and as well as skin cancers.

Currently the federal government prohibitionist position on cannabis is hindering the medical community by delaying vitally important clinical cannabis research.

 I was quite elated when I recently saw that the NCI posted on their webpage

“In the practice of integrative oncology, the health care provider may recommend medicinal Cannabis not only for symptom management but also for its possible direct antitumor effect.”

 I foolishly thought that finally there would be official recognition of the modern peer reviewed science that shows the cancer killing properties of cannabinoids. Sadly, this statement was removed, without comment, within hours of its posting.””

Cannabis Science Extracts Kill Cancer Cells In Cancer Patients Being Treated Through Its Licensed Distributor Rockbrook

“Cannabis Science, Inc. a pioneering U.S. biotech company developing pharmaceutical cannabis (marijuana derivative) products, is pleased to announce that numerous patients are reporting that Cannabis Science extract treatments are killing cancer cells.

Unlike most conventional cancer treatments, cannabis has an outstanding safety profile, and patients in states with medical marijuana laws are able to make an informed decision to legally try various cannabis preparations to determine what is most effective for their particular condition.

Some of these scientifically informed patients have chosen to self-administer Cannabis Science extracts supplied by Rockbrook to treat their own cancers. Cannabis Science is delighted that patients are reporting dramatic improvements in their conditions, including basal cell carcinoma, non-small cell lung cancer accompanied by COPD (chronic obstructive pulmonary disease), ovarian cancer, and glioma.”
