The U.S. Patent Office issued patent #6630507 to the U.S. Health and Human Services filed on 2/2/2001. The patent lists the use of certain cannabinoids found within the cannabis sativa plant as useful in certain neurodegenerative diseases such as Alzheimer’s, Parkinson’s, and HIV dementia.
US Patent 6,630,507 Cannabinoids as Antioxidants and Neuroprotectants
Since cannabis sativa (marijuana) contains compounds recognized and endorsed by an agency of the U.S. government – Why is it that marijuana remains listed as a Federal Schedule One drug? The issuance of patent #6630507 is a direct contradiction of the governments own definition for classification of a Schedule 1 drug.
