I heard the only reason it was illegalized was because DuPont and other chemical companies didn't want hemp oil fueling the cars to come. Henry Ford powered the Model A off Hemp Fuel. And the only reason it's still illegal is because the government doesn't wanna say "Yeah, we screwed up. We where wrong" and because they would look like idiots for fighting the war on ganja and wasting money for so many years. Just some personal thoughts
