The vaping craze presents mother and father with some troublesome points, in keeping with Keyes and Richter. Not solely is marijuana use more durable to note, however youngsters are additionally seeing marijuana vaping merchandise marketed in every single place, together with on social media, they identified.

“It is not a matter of whether or not your youngster can be uncovered to this, however when,” Keyes mentioned. “The perfect factor mother and father can do is to speak to their youngsters about marijuana use, and begin early — in center college.”
