E-cigarette maker Juul Labs Inc. said Thursday it will completely halt U.S. sales of all flavors except tobacco, mint and menthol, as the company faces heightened scrutiny from regulators, lawmakers and state attorneys general over the appeal of its nicotine products to teenagers.

Thursday's move, which ends online sales, means Juul's mango, fruit, creme and cucumber nicotine pod flavors will no longer be available for sale anywhere in the United States. The company pulled those flavors from retail stores last year but continued to sell them on its website, with what the company said were "strict age-verification controls."

Juul's new chief executive, K.C. Crosthwaite, a veteran of Marlboro maker Altria Group Inc., announced the move Thursday as the company attempts to repair its relationship with regulators.
