"Cannabis" is really the same word as "canvas", because that's what they made it out of. George Washington used to grow hemp, in quite a big way.

But he wasn't just growing it for the fibre, it appears. There are records extant about his arranging to destroy the male plants in the harvest, at times, which is what you do when you want to make sure the female plants produce lots of resin instead of seeds. For making rope, the male palnts are actually better.

You had a better class of George in charge over there, in those days.
