Nice Cloud LLC d/b/a Nicecloud Vapor, a manufacturer and distributor of e-liquid tobacco products, was cited for failing to comply with Federal Food, Drug, and Cosmetic Act requirements applicable to tobacco products containing nicotine from any source. The company's e-liquid products were subject to FDA jurisdiction under section 901(b) of the FD&C Act and required premarket authorization as "new tobacco products," but the inspection records indicated the company was manufacturing, selling, and distributing these products without obtaining the necessary FDA approval. The warning was issued following FDA's review of inspection records and reflected the agency's expanded regulatory authority over nicotine-containing products that took effect in April 2022.
