Tv is bad on children not teenagers. As teenagers they are already desensitized to it already.
In all honesty, I would rather have my teenagers in the house watching cops or some other crap programing then outside smoking dope somewhere that they think no one with find them.
It used to for me, I used to call it a weed hangover...just don't smoke right before bed ;)
Try *67 before you dial, that always works for me!! Good luck
