Durham police are alerting the public after seizing lollipops possibly containing THC, the active ingredient in marijuana, from a teen in Whitby.

The parents of a 17-year-old male called police to their home Tuesday after discovering he had purchased drugs.

Police seized a quantity of marijuana and three lollipops believed to contain THC, the active ingredient in marijuana. The lollipops, which appear to be homemade, have been sent for testing to determine their contents.

This is the first time Durham police have encountered this kind of lollipop, Sgt. Bill Calder said. Police are concerned because “there could be anything in them,” he said.

The 17-year-old, who cannot be named under the Youth Criminal Justice Act, was arrested and charged with drug-related offences.
