The Weyburn Police Service is reminding trick-or-treaters to be extra mindful of the presence of cars while out collecting candy tonight, and don't consume anything of unknown origin.

Acting Police Chief Rod Stafford said parents should also take an interest in the candy their children receive.

"We would urge parents, especially, when the children get home to check their bag, any handmade treats that you don't know specifically where they came from should be discarded immediately," Stafford urged.

"We've had issues with pins and razors in handmade treats before, not for the last few years, but certainly in recent memory we have," he cautioned.

He noted there is also an added concern in light of the recent legalization of cannabis edibles.

"It's too new, I guess, to say whether we're going to have any trouble," Stafford said. "Generally, that fits in to the handmade/ hand wrapped treats, and if you don't know specifically where something came, our suggestion is to simply garbage it and move onto something that is safely packaged or that you know without a doubt who that caramel apple came from or who the brownie came from."

He said drivers should pay extra attention given the road conditions.

"With the snow we weren't expecting this early, it is slippery taking longer distances to stop if somebody does dart out from between vehicles," he warned.

He said trick-or-treaters should also consider their safety a personal responsibility.

"We would urge parents and trick-or-treaters, equally, that because it is cold, you may be bundled up a little more than normal in your costume, with a hood on or a toque and that, and you may not be able to see around you quite as easily as if you didn't have that on, so there's some onus on the trick-or-treaters to pay a little extra attention before they cross the road as well," he said.
