YES! The changing legality of cannabis is hard to keep track of, but when it comes to CBD oil from hemp, it’s easy. Unlike marijuana, hemp is legal in all 50 states. As a hemp product, that means CBD oil is legal, too. Medical marijuana is legal in about half of states, but with negligible amounts THC, those rules don’t apply to hemp. It’s perfectly legal to buy and possess CBD oil in all 50 states as long as it’s obtained from hemp and has less than .3% THC.
