Before you start growing your own hemp plants, it is worthwhile to read up on the history of hemp growing in the US. At one time it was legal. Not only was it legal, the law required the growing of it.
According to the book Healthy Oils, hemp is another word for the plant Cannabis sativa L. Marijuana comes from this same plant genus – as does cauliflower and broccoli. However, the strains used in consumer and industrial products contain only a negligible amount of the intoxicating substance delta-9 tetrahydrocannabinol, or THC. Thus industrial grade hemp is not marijuana. Yet, since the 1950’s the growing of hemp has been effectively prohibited.
But this has not always been the case. Going back to 1619 America’s first marijuana law was enacted at Jamestown Colony, VA. All farmers were ordered to grow Indian hemp seed. Mandatory cultivation laws were enacted in MA in 1631, in CT in 1632, and in the Chesapeake colonies in the 1700’s.
Cannabis hemp was even used as legal tender in most of the Americas from 1631 until the early 1800’s. The reason for making it legal tender was to encourage farmers to grow more. You could then pay your taxes with cannabis hemp throughout America for over 200 years. If you did not grow hemp during periods of shortages, you could be jailed.
In fact, George Washington and Thomas Jefferson used enslaved African labor to grow this crop on their plantations.
