Nicotine sachets: the microplastic risk has not been assessed by the FDA

According to an investigation by The Examination, the U.S. Food and Drug Administration (FDA) authorized the sale of Zyn nicotine pouches, manufactured by Philip Morris International, in January 2025 without having precisely determined the material these pouches are made of or assessed their potential for releasing microplastics. These claims come from a former toxicologist at the agency, Christy Leppanen, who alleges she was sidelined when she sought additional information from the manufacturer.
