PHILADELPHIA (AP) – Philadelphia has filed a lawsuit against Juul Labs, accusing the company of being responsible for what city health officials call an epidemic of e-cigarette use among teens and young people. The city is the latest in a long string of states, cities and other municipal entities to file a lawsuit against the company over use of electronic nicotine devices by young people. The lawsuit announced Wednesday was filed in California, the home of Juul Labs. Philadelphia officials allege that Juul intentionally marketed its products to young people. Juul said Wednesday that it will continue to work to “combat underage use” and and will respond to the allegations “through the appropriate legal channels.”
