Teen vaping continues to become more widespread in the U.S., especially as manufacturers are getting more creative in making vape devices that are masked as everyday items.

According to the National Youth Tobacco Survey by the CDC, the number of high school students who vaped rose from 2017 to 2018 by 78 percent—and it’s not likely to die down anytime soon. While local governments have been extra vigilant in shutting vape lounges and banning indoor vaping, the numbers continue to rise.

In a series of interviews with teens, USA Today reported that vaping is considered a status symbol among teens. This is particularly highlighted by the fact that many vaping accessories are so creatively constructed, making them all the more covetable. Others students also said that vapes are a preferred alternative to smoking actual cigarettes because of their sweet taste and smell. There seems to be an impression that not only is vaping cooler, it is also cleaner and healthier.

As parents, how do you find out if your teen is vaping? There are typical signs that you can watch out for.

1. Watch out for vaping paraphernalia.

This is the first and one of the more definite signs of teen vaping. That said, you should try to be more familiar with the different types of paraphernalia, which can resemble USB sticks or pens. Some parents don’t even recognize a vaping device even when it’s right in front of them.

2. Bloodshot eyes

Vaping does not usually have physical manifestations, but a teen that has constantly bloodshot eyes can provide a clue to what he or she is up to.

3. Sweet, fruity smells

E-cigarettes are attractive to teens because they don’t taste like the normal cigs. They usually smell like fruits or bubble gum. So if you suddenly smell these on your teen’s clothes, it can be a sign that you should start investigating and asking questions.

4. Irritability

If you’ve been noticing the above plus an unusual irritability in your teen, it could signal nicotine withdrawal.

One thing you should also monitor is what your teen is buying online because most online stores do not regulate their buyers and will release products regardless of age. So if your son or daughter has been receiving packages at home that are addressed directly to them, be wary.

Overall, the best way to make sure that your teen is not vaping or doing anything illegal is to have a direct conversation about your concerns. You can get a medical professional to help discuss the dangers of vaping, if that helps, too.
