Police in Winnipeg say they've received at least half a dozen reports of children receiving candy containing THC while trick-or-treating.

The Winnipeg Police Service says the reports all included the same product, "Medicated Nerds," with a label indicating that it contains 600 milligrams of THC, given out to children for Halloween.

They said the candy was found in sandwich bags that also came with full-sized chocolate bars. However, the candy was not tested and police could not say for certain if they contain THC.

Winnipeg police Const. Dani McKinnon said there have been no reports of any children there having ingested the candies. She encouraged caregivers to check children's Halloween treats if they haven't already.

"Look at all of the candy that you have, and if you see one of these items that are suspicious, contact the police."

Winnipeg police received reports about the candy only from the South Tuxedo area of the city.

Based on the labelling, McKinnon said, it is not a product approved by the federal government.

"There's very specific information that must go on those authorized items," she said. "These particular candied items that we have seized do not meet those requirements."

McKinnon added that Winnipeg schools have also been notified.
