Prohibition didn't work for alcohol, so let's try it for candy!

Schools have been individually banning junk-food sales for years, and enforcement was increased in 2005 when Gov. Arnold Schwarzenegger passed legislation to combat childhood obesity, according to the office of the governor.
Since then, schools have slowly adjusted by offering more healthy alternatives, such as baked chips and granola bars.
But Nason said that he sees just as much candy and soda as ever, because students still bring it from home — for lunch, and to turn a profit.
“I think it’s original purpose was pretty good, but it doesn’t seem to be making that big of a difference,” said teacher Rolayne Allen of the junk-food ban.
Teachers are instructed to confiscate candy when kids have it in class, Nason said, and the punishment for making sales can be detention.
But confiscating candy all the time can be challenging, Allen said, especially around the holidays when students bring more of it to school.
