Connecticut launched a national investigation Tuesday into Juul vape pods, along with 38 other states.

They want to look at Juul's internal documents to see if they have been specifically targeting kids.

State Attorney General William Tong went to Hillhouse High School in New Haven to announce the investigation.

"We have a youth vaping epidemic that is sweeping the country," said Tong. "And we need to understand the extent to which Juul, and other manufacturers frankly, are responsible."

Juul said in response that it only markets to adults. To discourage young people, Juul no longer uses Instagram influencers to market. Three months ago the company stopped selling flavored vape pods.

"The products we pulled from market, the flavored products, represented more than 50% of our business at the time," said Juul co-founder James Monsees in July 2019.

A new crop of disposable vape brands still offer plenty of flavors and appeal to teenagers. Students say most of their classmates think vaping is a lot safer than cigarettes, and if habits are going to change, schools need to get a lot more aggressive.

Vaping manufactures will have to get FDA approval by May or stop selling altogether.

Juul is reportedly working on a device that locks out anyone under 21 years old.
