Massachusetts adopted the country’s toughest ban on the sale of flavored tobacco and vaping products, including menthol cigarettes, in response to a rise in youth vaping and an outbreak of vaping-related serious lung injuries.

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.

A 17-year-old Michigan boy facing “imminent death” from vaping injuries underwent a double lung transplant, the first in a patient suffering from the effects of e-cigarettes.

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

U.S. health officials reported 1,888 confirmed and probable cases and 3 more deaths from a mysterious respiratory illness tied to vaping, taking the total death toll to 37.

A Massachusetts judge ruled that a four-month ban on the sale of vaping products the state adopted in response to an outbreak of lung illnesses linked to e-cigarette use was likely “unlawful,” but he gave the state time to fix its defects.

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.

E-cigarette or vaping-linked lung injuries that have killed 29 and sickened more than 1,000 people in the United States are likely to be rare in Britain and other countries where the suspect products are not widely used, specialists said.

U.S. health officials said there may be more than one cause to the outbreak of the mysterious lung illness linked to e-cigarette use, and said they do not see a meaningful drop in new cases.

Kroger Co. and Walgreens Boots Alliance Inc. will stop selling e-cigarettes at their stores, amid heightened regulatory scrutiny of the product and reports of lung disease and some deaths linked to vaping.
