File talk:US-patent-6630507.pdf

Ha ha, ha, hahahahahahahahahahahahahahahaha this is the most, by far, completely, ironically, the funniest patent I've ever read. The same department that owns NIDA (who won't distribute weed for legal research) has patented hash medicine in light of its own research, about 4500 years after the Chinese started it. This is kind of like the story about Apple patenting the rectangle.
