Coffee shops and other places selling foods and drinks with cannabidiol, or CBD, are being forced to take them off the menu.
Back in December, the Food and Drug Administration said it's unlawful to add CBD to any food or drink.
Starting July 1, the Health Department's ban takes effect.
CBD is an ingredient in marijuana that many say does not in fact get you high, but officials say they will start issuing violations subject to fines on Oct. 1.
In a statement, the city's Health Department says, "The Health Department is responsible for promoting the safety of the food available to New Yorkers. The U.S. Food and Drug Administration has advised that it is unlawful to add cannabidiol (CBD) to food or drink."
