Killing cancer simply put by a biochemist, when THC connects to the CB1 or CB2 cannabinoid receptor site on the cancer cell, it induces an increase in ceramide synthesis that leads to cell death. A normal cell does not produce ceramide when it is near THC; therefore it is not affected by the cannabinoid.
The reason the cancer cell dies is not because of the cytotoxic chemicals, but because there is a small shift in the mitochondria. The purpose of the mitochondria within a cell is to produce energy for the cell to use. As the ceramide is produced, it turns up the sphingolipid rheostat. This production increases the mitochondrial membrane permeability to cytochrome c, which is vital protein in energy synthesis. The cytochrome c is then pushed out of the mitochondria, which ultimately kills the source of energy for that particular cell.
The presence of ceramide leaves no possibility of cancer cell survival. This is because it causes genotoxic stress in the cancer cell that generates a protein call p53, which disrupts the calcium metabolism in the mitochondria. Ceramide also disrupts the cell’s digestive system that produces nutrients for all cell function, and actively inhibits pro-survival pathways.
The key to the cancer killing process is the accumulation of ceramide in the system. This means that by taking THC rich cannabis extract (with the minimum of 55% THC) ,at a steady rate over a period of time the patient will keep metabolic pressure on these cancer cell death pathways.
