Senate Minority Leader Charles Schumer was at Depew High School on Monday, renewing his call for a federal ban on flavored e-cigarettes.

He's also calling for a national awareness campaign to outline the dangers.

Schumer also urged President Trump and the Food and Drug Administration not to waver on a possible national ban.

The Centers for Disease Control and Prevention say the number of high schoolers using e-cigs nearly doubled from 12% to 21% between 2017 and 2018.

School prevention leaders say vaping affects brain development for those under 21, which has caused an uptick in symptoms that show it's an addictive health risk.

"…Difficulty focusing, impacting ability to learn, memory retention, signs of withdrawal, headaches, fatigue, stomachaches, seizures, profuse vomiting," said Gwendolyn Bork, FOCUS president.

Schumer says he has sponsored legislation to ban the products before year's end if the Trump administration fails to do so.
