The History of Halloween Candy Irradiation

In 1959, a man in California gave candy-coated laxatives to trick-or-treaters. He was charged with something called outrage of public decency and unlawful dispensing of drugs. The real place where it starts is in 1964, there's a woman in Green Law, New York,. I was not aware of this, but apparently there are people who feel very strongly that children over 12 should not be trick or treating.
