Hemp in the United States was a legal crop in the 18th and 19th centuries. Production was in fact banned in the mid-20th century, but it returned to being a legal crop in the 21st century. Hemp is now a true American crop. In short, hemp was declared illegal because he was guilty by association, a victim of a war against his identical twin.
And while the war on drugs may seem to be a far cry from the advances being made through federal hemp policy and state marijuana laws, the federal prohibition of marijuana continues. In particular, hemp was seen as a cheaper means of producing the lucrative cannabidiol (CBD), the cannabis compound touted for its health and well-being benefits. When it comes to hemp-derived CBD, it's highly unlikely that brand protection will be available for any product that isn't approved by the FDA. With a broader avenue open for hemp research, the FDA is more likely to update its position on CBD as a dietary supplement.
With this new bill, additional research requirements were established on hemp and its cannabinoids (including CBD).
