The Food and Drug Administration (FDA) has sent a warning letter to the marketers and distributors of a snortable chocolate powder called “Coco Loko,” for selling unapproved new drugs and misbranded drugs, HealthDay reports.

The FDA sent a similar letter to the distributors of a drink called “Legal Lean Syrup.” The agency said the claims made in the promotional materials for both products demonstrate that they are intended to be used as alternatives to illicit street drugs, and the products, as labeled and marketed, may pose safety concerns.

“As a physician and a parent, I’m deeply troubled by the unlawful marketing of these potentially dangerous products, especially since they are so easily accessible by minors,” FDA Commissioner Dr. Scott Gottlieb said in an agency news release. “Encouraging the use of snortable chocolate as an alternative to illegal street drugs is not acceptable — there are very real consequences to snorting any powder, not to mention the societal dangers of promoting drug abuse.”
