While the number of teen cigarette-smokers is on the decline, more and more people are vaping now.

Administrators at Shenendehowa Central School held an informational meeting Monday night to discuss potential health issues with parents.

The presentation was a show-and-tell for parents to learn what to look for and a chance for them to ask questions.

Officials warned that it isn't just nicotine.

Vape pens can also contain drugs, even pointing to a few incidents in other areas where fentanyl was found in some vaping products.

Parents who spoke with Spectrum News with say it’s a concerning trend.

“It’s scary because we don't know anything about it,” said parent Christina Moulton. “When they’re like, ‘It’s fine, it’s fine,’ they don't know. I’m afraid in 10 years, they’re going to say, ‘Oh my gosh, my health, my lungs.’”

Now Shen is also talking prevention. The district says schools will have monitors outside bathrooms and do random pop-ins to ensure students are not smoking or vaping at school.
