The Florida Sheriff’s Association is warning parents about the threat of marijuana laced candy showing up in their kid’s trick or treat bags this Halloween.

Jerry Demings, the association’s president, made this claim during a press conference Monday in Orange County. It comes on the brink of vote that could legalize medical marijuana in the Florida. Amendment 2 is on the ballot election day and the Florida Sheriff’s Association does oppose the legislation.

A pro-medical marijuana group is taking issue with Demings’ claim, calling it unfounded. A spokesperson for United for Care says there are no cases to support the Sheriff’s claim, and according the AP they might have a point.

Designs claims that marijuana candies were given out to kids in Colorado. The latest data from the state in 2014 shows there were zero reported cases of people giving out marijuana candies to kids.

But authorities maintain this is a legitimate warning. They say to look for suspicious packaging and unusual names on the wrappers of candies your kids bring home this Halloween.
