Government regulators are expected to soon rule on the legality of a controversial drug called kratom.
Federal agencies have called kratom a dangerous opioid, but advocates say it's saved their lives.
According to Business Insider, hard science on how kratom works has been thin on the ground.
But this summer, a researcher isolated kratom's two key ingredients to see how they affect behavior in rats.
Preliminary results suggest the drug could hold promise for people with addiction.
Right now, kratom is legal in most states, where it is sold in whole plant form as a supplement.
