One should be cautious about imposing 2014 assumptions on 1700s people.
Did GW grow marijuana, or hemp? We all know that he (and many other planters) grew hemp. To make rope.
He was concerned about being buried alive? So were many other people of his era. That is where the term “bellringer” is rooted. Many graves had a bell mounted on them with a string leading into the coffin, just in case the deceased woke up. You’ve heard of “waking the dead”? Or a “Wake”? That is because people occasionally woke from a coma.
I have one severely autistic grandchild and another who is classed as Aspbergers. They are both great kids, but neither of them would ever be able to inspire the loyalty of the troops in a Revolutionary War, nor be the favored guest at a posh Richmond Ball. That kind of social awareness and leadership is just not on the Autism spectrum.
I question the scholarship behind your list.
There's a bit more to it than that.
Virginia colonial law required that every farmer with an acreage over a certain amount had to devote a certain percentage of that acreage to hemp.
Hemp was used for more than rope. Hemp was used to make paper, cloth and cotton bagging. Cotton bags made of hemp fiber had a lower co-efficient of friction that cotton bagging made of jute fiber (burlap). When a slave had to process a bagful of cotton (before Whitney's cotton gin), it was easier to pull cotton bolls out of a hemp bag than a burlap bag.
But every medicine cabinet of the era had extract of hemp in it. The medicinal properties were well know, and it was used for headaches, menstrual cramps and most ailments that would be later treated by extract of willow bark (aspirin). Washington made a tea of hemp to wash out his gums and soothe the pain of his dentures.
Hemp was widely used for medicine.
