Manufacturers of oral nicotine products – pouches, tablets, or lozenges – are using splashy ad campaigns to appeal to retailers, particularly focusing on profitability, convenience of use, and availability of non-tobacco flavors, according to a study published in November 2024 by a multi-institution team that included two Yale researchers. Nicotine pouches are relatively new products in the U.S. tobacco market but have been gaining rapid popularity.
