Would this be the same founding father who was sworn in on a Bible printed on Hemp?? And the same founding father who grew hemp at Mount Vernon?? Jefferson also had journal entries about separating the males in part of his hemp crop. The ONLY reason for that, is if you wanted to smoke the flowers.
Hemp has been with man since the garden of eden. They dug up mummies on the steppes of Asia, who were buried with little pouches of weed. Ditto on the Egyptian pharoahs.
The historical record is VERY clear on the usefulness of hemp. Yes, we can discuss that for weeks. The prohibitionists don't have an historical leg to stand on.
