The U.S. Food and Drug Administration said on Sept. 9 the regulatory agency needs more time to decide whether e-cigarette maker Juul Labs Inc. and other major manufacturers can sell their products in the United States.

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

The United States plans to raise the age limit for vaping to 21, U.S. President Donald Trump said.

E-cigarette maker Juul Labs Inc. 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 the company’s nicotine products to teenagers.

A U.S. House panel sent letters to four e-cigarette companies asking them to stop all print, broadcast and digital advertising of their products in the United States.

Juul Labs said the company would suspend all broadcast, print and digital product advertising in the United States and replaced CEO Kevin Burns.

Congressional Democrats threatened to subpoena Juul Labs if the e-cigarette maker does not provide documents relating to the company’s products and marketing practices, as a House panel looks into whether Juul deliberately targeted children.

The Trump administration announced plans to remove all flavored e-cigarettes from store shelves in a widening crackdown on vaping, as officials warned that sweet flavors had drawn millions of children into nicotine addiction.

The U.S. Food and Drug Administration issued a warning letter to Juul Labs Inc. over the company’s marketing practices for e-cigarettes.

San Francisco is the first major city in the United States to ban the sale of e-cigarettes as officials look to control the rapid uptick in teenage use of nicotine devices made by companies such as Juul Labs Inc.
