How about not selling spray paint to kids, or teens. That is what they use for the gang markings and graffiti. Sounds crazy but here is another idea. Want to purchase it? Then before buying, register with your license just like you have to when you purchase certain sinus medications. For those who don't know it is used as a substance to make illegal street drugs. I do wonder, where are these parents. If they can't handle them then let the courts. Turn them over to someone who can. Please !
