Two personal injury lawsuits against Juul Labs have landed in federal court in Trenton, joining a growing number of cases lodged against the company on behalf of people using its e-cigarettes.

A 20-year-old Juul user with the initials P.O., who claims he became addicted to nicotine from using the company’s products, filed a failure-to-warn suit Tuesday against Juul in U.S. district court in Trenton. Also Tuesday, a 19-year-old Juul user’s products liability suit against the company was removed from Middlesex County Superior Court to U.S. district court. Both suits were filed by Domenic Sanginiti of Stark & Stark in Princeton.
