Police near Montreal say they seized a small quantity of jujubes in May that tests eventually showed were laced with THC, the active ingredient in cannabis.
Laval police sergeant Frederic Jean says officers stumbled on the special sweets after they spotted youngsters smoking marijuana.
There were red ones, green ones and yellow ones and all had a fruity smell.
Jean says the discovery was a first for the police department.
Authorities are warning the public to be vigilant and also asking for help in finding the person or people who made the candies.
