BATON ROUGE, La. (AP) — Attorney General Jeff Landry confirmed Wednesday that Louisiana is among the 39 states investigating the marketing and sales practices of e-cigarette maker Juul Labs.

The states are looking into claims the company targeted youths with its vaping products and made misleading claims about nicotine content in its devices and the risks and effectiveness of its products as smoking cessation devices.

Attorneys general from Connecticut, Florida, Nevada, Oregon, and Texas announced Tuesday they are leading the multistate investigation.

“As a father, I am deeply troubled by the alarming number of middle school and high school students using e-cigarettes,” Landry said in a statement announcing Louisiana’s involvement in the review.

San Francisco-based Juul is facing lawsuits by teenagers and others who say they became addicted to the company’s vaping products. The company said it has stopped television, print, and digital advertising and eliminated most flavors in response to concerns by government officials and others.
