(1) It was smoked by Chinese railroad workers and used as an excuse for how "lazy immigrants" were taking American jobs (2) Hemp fiber was a serious competitor to synthetic fibers being produced by chemical companies. (3) Henry Ford had built a car entirely out of hemp, and then used hemp as the fuel for the car in order to demonstrate how viable the product could be for the automotive industry (which threatened big oil). (4) Harry J. Anslinger & William Randolf Hearst and their support from dupont, big pharma, the timber industry, and their control of the media and representation in politics. There's really so much to the story that it's nearly impossible to write it all down in one place, but it's a subject that's definitely worth researching.
