That lack of smoke can be an issue of types: Youngsters can conceal marijuana vaping extra simply than smoking, Richter mentioned, as a result of there is no telltale pot odor.

The vaping craze presents dad and mom with some troublesome points, in accordance with Keyes and Richter. Not solely is marijuana use tougher to note, however children are additionally seeing marijuana vaping merchandise marketed all over the place, together with on social media, they identified.

“It isn’t a matter of whether or not your youngster might be uncovered to this, however when,” Keyes mentioned. “The very best factor dad and mom can do is to speak to their children about marijuana use, and begin early — in center college.”
