INDIANAPOLIS (AP) — An Indiana family is suing Juul Labs Inc., accusing it of making electronic cigarettes that contain excessively high levels of nicotine without warning that they’re addictive.

The Indianapolis Business Journal reports that the McCullough family of Carmel filed the lawsuit Aug. 20 in U.S. District Court in Indianapolis.

Thomas McCullough says his 17-year-old son has been vaping Juul e-cigarettes since 2015 and that he’s addicted. The lawsuit says each Juul e-cigarette contains three times more nicotine than is needed to satisfy the nicotine cravings of an adult smoker.

Juul says the lawsuit is without merit.

The California-based company has long been accused of targeting teenagers with candy-flavored products. Illinois health officials last week announced what they believe was the first vaping-related death in the U.S.
