CBD was once considered illegal because it is a byproduct of the cannabis plant which also produces THC a psychoactive compound, found in marijuana. Unlike marijuana, which is bred to have a high level of THC, CBD that is derived from hemp has less than .3% THC in it. That means it is not psychoactive.
This is the main reason why the Farm Bill legalizing hemp CBD was finally enacted – with Congress and President Trump overwhelmingly realizing that hemp CBD offers great benefits, and without the side effects associated with THC. The new legislation is a milestone that makes it easier for those who rely on CBD to take full advantage of the benefits it provides.
