Under U.S. federal law, marijuana is defined as having no medical use. Other countries like Jamaica had to follow, or lose any financial aid from the US.
So it might come as a surprise to many to hear that the US government owns one of the only patents on marijuana as a medicine.
The patent (US6630507) is titled “Cannabinoids as antioxidants and neuroprotectants” and was awarded to the Department of Health and Human Services (HHS) in October 2003.
It was filed four years earlier, in 1999, by a group of scientists from the National Institute of Mental Health (NIMH), which is part of the National Institutes of Health (NIH).
