Cannabis is not indigenous to North America. It was introduced during colonization, probably in the 1600's as a fiber source for rope. It was a required crop during the Revolution, and a penalty was imposed if farmers did not use a certain percentage of their land for hemp production. It was that important. Not only for rope, but clothing as well. If you've ever heard the term "homespun" referring to clothing, it was the spun fibers of hemp that was used to make cloth.
It was an important crop for ship rope up until WWII, until DuPont created Nylon, after which it became obsolete due to the superiority of of nylon. It once flourished all over the South and Mid West, until Reefer madness led to the eradication of it. There are still feral remnants of it in Indiana and a few other states. Those feral plants are descendent of a thriving hemp industry this country once had.
