Juul, retailers at odds over software change

Details: The major e-cigarette maker is battling a slew of lawsuits from schools, state and city-wide bans and scrutiny from regulators, public health advocates and parents in what the Food and Drug Administration calls a "vaping epidemic" among teens.

• Juul already axed its social media and ceased production of flavored vape pods, which critics say fueled teen usage.

Meanwhile: There are 1,299 confirmed and probable cases of lung injury in 49 states and 26 deaths associated with e-cigarette use, the CDC said this week. Juul is not directly connected with the illnesses. Officials still have not concluded a cause.
