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 FDA says the drug, which is derived from the kratom plant, can easily be purchased in gas stations, corner stores, and vape shops.

The synthetic variant is legal and has opioid-like effects. One official called it “a recipe for a public safety disaster.”

The FDA announced that it is urging the Drug Enforcement Agency to "classify 7-OH as a Schedule 1 substance, placing it on a list of drugs that include heroin, lysergic acid diethylamide (LSD) and ecstasy," said The Hill. This would make the drug harder to obtain at locations like gas stations and convenience stores.
