A cautionary tale has developed a new twist this year, as an alarming opioid has become the latest drug feared to be lurking inside trick-or-treat hauls for Halloween. It's been an annual tradition for people to raise concerns of drugs like marijuana edibles or dangerous objects such as needles to be inside candy for the holiday.
