Kratom, made from Southeast Asian tree leaves, is marketed as a natural remedy for pain and anxiety. 7-OH, however, is a concentrated kratom byproduct that can come in the form of pills, gummies, drink mixes and shots. (Reversal agents like naloxone do work on 7-OH and are recommended to use during an overdose.)

Attorney General James Uthmeier said Wednesday that his office is reclassifying concentrated 7-hydroxymitragynine products as a Schedule 1 drug in an effort toremove the product from stores in Florida.

Florida Attorney General James Uthmeier issued an emergency rule banning a compound known as 7-OH. This is a concentrated byproduct of kratom.
