Federal officials promised on Tuesday to crack down on a potent semisynthetic opioid found in convenience store gummies, drinks and dietary supplements by putting the substance in the most restricted class of drugs.

The opioid-like substance is sold in gummies, tablets and drinkable shots, mainly in gas stations and convenience stores.

The FDA recommendation follows a detailed scientific review and is part of broader efforts to address concerns about the rise of 7-OH opioid products. Currently, 7-OH has no FDA-approved drug uses and is not legally permitted in dietary supplements or conventional foods.
