For years, parents have been wringing their hands about how to tame cyberbullying and keep sexual predators from their children. Well, they’d better add this one to the list as well, experts say.

As helpful as social media can be, it can be a direct hit to an overdose, said Louise Stanger, a social worker and interventionist based in Southern California. She said parents should rethink when, where and how they allow their teen to use their devices.

Parents must be vigilant in their communication with their teens, and teens must beware of the challenges a digital age faces.”
