The state of California on Monday sued e-cigarette maker Juul Labs Inc, alleging the San Francisco company engaged in a “systematic” and “wildly successful” campaign to attract teenagers to its nicotine devices.

Axar.az reports citing Reuters that the lawsuit draws on internal correspondence and other evidence, asserting the company did little to prevent sales to underage customers. It also claims that Juul used a “flawed” age-verification process for online sales.

Filed in California state court in Alameda County, the lawsuit also cites passages from a recent Reuters investigation that documented how Juul disregarded evidence soon after its launch in 2015 that teenagers were attracted to the product.

The Reuters story documented how Juul rarely mentioned nicotine in early consumer marketing, while at the same time pitching retailers on Juul’s unique addictive power.

The lawsuit seeks monetary damages based on violations of state laws governing false advertising and unfair competition, among others.
