Sadly if that does happen, other places will jump on the bandwagon. It's easy to hide behind the "it's for the children" excuse for making up these shitty laws.
Don't blame the schools. I'm sure they don't/won't want anything to do with this bullshit. I'm sure the teachers and school administrators are sick and tired of the politicians and people who think school teachers are surrogate parents who are responsible for parenting kids as well as educating them.
if the generation that wants to create this horse shit law didn't do drugs as teenagers, no one would give a fuck about the beatles.
In a related story, Nassau County legislators voted to pass a law requiring all parents to sign an affidavit saying that they pinky swear their children cleaned their plates at dinner.
