A psychologist's advice: How to talk to your kids about social media and drug abuse

Psychologist John Duffy writes that while drug dealers on the street enticing kids to take a hit haven't disappeared, teenagers tell him that social media is increasingly an almost invisible way that dealers are reaching young people.

This phenomenon can lead to tragic consequences. Some kids are overdosing on these drugs, occasionally laced with potentially lethal substances. This was the case in the devastating death of relationship therapist and TV host Laura Berman's son, who allegedly bought fentanyl-laced Xanax on Snapchat.
