Does smoking pot help reduce tumor size in cancer patients?

Research indicates the surprising answer is YES – inhaling cannabis does seem to reduce the size of tumor cells in both human test patients, and animal testing done on the matter.

Read up on the cannabis research in detail at the links below. They show research indicating the uses of medicinal cannabis for reducing the size of tumors in both cancer patients and lab animals, in several tests done.

“Investigators at the British Columbia Children’s Hospital in Vancouver documented the mitigation of residual tumors in two adolescent subjects who regularly inhaled cannabis. Authors determined that both subjects experienced a “clear regression” of their residual brain tumors over a three-year-period.”

Gliomas (tumors in the brain) are especially aggressive malignant forms of cancer, often resulting in the death of affected patients within one to two years following diagnosis. There is no cure for gliomas and most available treatments provide only minor symptomatic relief.

In addition to cannabinoids’ ability to moderate glioma cells, separate studies demonstrate that cannabinoids and endocannabinoids can also inhibit the proliferation of other various cancer cell lines, including breast carcinoma,[11-15] prostate carcinoma,[16-18] colorectal carcinoma,[19] gastric adenocarcinoma,[20] skin carcinoma,[21] leukemia cells,[22-23]neuroblastoma,[24] lung carcinoma,[25-26] uterus carcinoma,[27] thyroid epithelioma,[28] pancreatic adenocarcinoma,[29-30], cervical carcinoma,[31] oral cancer,[32] biliary tract cancer (cholangiocarcinoma)[33] and lymphoma.[34-35]

Studies also indicate that the administration of cannabinoids, in conjunction with conventional anti-cancer therapies, can enhance the effectiveness of standard cancer treatments.[36] Most recently, investigators at the University of California, Pacific Medical Center reported that cannabinoids possess synergistic anti-cancer properties — finding that the administration of a combination of the plant’s constituents is superior to the administration of isolated compounds alone.[37]

Consequently, many experts now believe that cannabinoids “may represent a new class of anticancer drugs that retard cancer growth, inhibit angiogenesis and the metastatic spreading of cancer cells.”[38-39]
