Colon cancer: British researchers demonstrated that THC triggers cell death in tumors of the colon, the second leading cause of cancer deaths in the United States.

Endocannabinoids are the only neurotransmitters known to engage in “retrograde signaling,” a unique form of intracellular communication that inhibits immune response, reduces inflammation, relaxes musculature, lowers blood pressure, dilates bronchial passages, increases cerebral blood flow (a rush of thoughts!), and normalizes overstimulated nerves. Retrograde signaling serves as an inhibitory feedback mechanism that tells other neurotransmitters to cool it when they are firing too fast (213).

Prostate cancer: Researchers at the University of Wisconsin found that the administration of the synthetic cannabinoid WIN-55,212-2, a CB-1 and CB-2 agonist, inhibited prostate cancer cell growth and also induced apoptosis (programmed cell death, a good thing where cancer cells are concerned). - Martin A.
