Okay, great for Dad. He has now ensured that the "clean" kids won't associate with his "pothead" kid, and made the kid instantly "cool" with the pothead crowd.
If the kid had to look around for a safe seller for drugs before (safe meaning not a narc), he never will again.
The kid has also learned the lifelong useful lesson of the eleventh commandment: "Don't get caught."
Wow. Dad sure has "helped" his teenager. How can he teach his kid to think ahead and consider the problems* his behavior can cause if he doesn't?
Hey, Dad! If your parenting techniques make the news, you've gone overboard.

* I don't say "consequences" because the word has become a euphemism for punishments. It's vital to teach a child to distinguish between punishments deliberately inflicted by someone versus natural consequences that inevitably follow from what you did, even if you got away with it.
