Absolutely. In fact, I think one person referred one time to the fact that it's unlawful to have a child in a car while you're smoking a cigarette, and you could easily be charged and convicted. But the same child could be in a house where they have a grow-op or a crystal meth lab, and you wouldn't be able to charge and convict them of a secondary offence.
