(Porter & Jacobson, Epilepsy & Behavior, 2013) Medical Uses? THC is more effective at blocking an enzyme that causes the brain damage common to Alzheimer's disease than approved drugs already on the market low doses of THC inhibit AChE (breaks down acetylcholine), may thus improve learning and memory. The drug also appears to prevent the formation of neurofibrillary tangles Eubanks, L.M., et al. (2006) A Molecular Link between the Active Component of Marijuana and Alzheimer's Disease Pathology, Molecular Pharmaceutics, 3, 773-777. Medical Uses? 2004 - Israeli soldiers suffering from combat stress were treated with cannabis to relieve symptoms – PTSD trials are ongoing –THC may silence genes that code for vascular endothelial growth factor (VEGF) VEGF stimulates the growth of blood vessels in tumors Does cannabis increase the risk of chronic psychotic illness?
