Dear sirs, There is a new reason to support the state Congress' bill calling for legalized medical marijuana. The new reason is Alzheimer's disease. (As well as other diseases.) The Scripps Research Institute in California reported that THC inhibits the enzyme amyloid plaque. This is believed to be the cause of Alzheimer's disease. THC or cannabis in recent scientific studies may simultaneously treat both the symptoms and progression of the disease. While this will not bring back people who are suffering from AD, it will prevent people from getting it and help people who are suffering from the symptoms of AD and can prevent it if they start using it early enough.
