Your child comes home from school and looks a little tired.

You come up to see how they are and you get a whiff of something that smells like burning rope.    

And you think you recognize this from a long time ago.     When you were around somebody who was smoking a joint.

You look into their eyes and yep,  they are red and kinda glassy.

 

Do you confront them at that moment,  or start paying more attention to what their doing and with whom?
