Gov. Brian Kemp on Friday signed a bill into law that allows Georgia farmers to grow hemp. The crop is the source of products ranging from rope to soap to CBD oil. Kemp had already signed a separate bill that allows medical marijuana, a stronger derivative, to be grown with some limitations in the state. With these developments, medical marijuana and hemp will soon crop up on Georgia farms. At the same time, CBD oil is a suddenly ubiquitous trend, showing up even on Atlanta menus.
