Hemp production has been federally legal since the passage of the Agricultural Improvement Act in 2018.
CBD Oil is legal in all 50 states to sell and ingest. And CBD will not appear in drug screenings like THC. Not that anyone should be concerned because CBD has no psychoactive properties (cannot get you high). CBD can be used safely in conjunction with other treatments. At this time, the FDA has not approved CBD for the treatment of any diseases or disorders.
