In the United States, about 15 children received psychedelic candy for Halloween. The incident took place in San Diego, Newsweek reports. Children between the ages of one and six took packages of chewing candies from the balcony of one of the houses, which were found to be laced with psilocybin. Parents noticed suspicious writing and contacted the police. The analysis confirmed the presence of a narcotic substance. Police later arrested two men and during a search of the house found methamphetamine, hash and weapons. When I was little, my grandmother told me not to take candy from strangers because they peed on it and then wrapped it in candy wrappers.
