Fact: DEA considers CBD oil as a schedule I controlled substance, with ONE exception
DEA considers CBD oil "marijuana extract" and remains on schedule I (same as cocaine and heroin). DEA has allowed a specific formulation, containing less than 0.1% THC, and approved by the FDA, to be reclassified Schedule V. This happened in October 2018.
This is often misquoted by CBD advocates as "DEA legalized CBD" when nothing of the sort took place.
With that said, DEA has bigger fish to fry, like the opioid epidemic. But it's illegal. And if your state law enforcement wants to bust you, it can, as a man in Indiana found out. He was arrested for possessing CBD oil and prosecutors chose not to charge him because the state legislature made CBD legal AFTER his arrest.
