Over 18 kilograms of drug-laced candy were seized from an apartment on a Pennsylvania university campus just days ahead of Halloween.

'It is a good time to remind parents to check the candy collected by their children during Halloween and to discard anything that looks suspicious.' - Patrick Carmody, Pennsylvania district attorney

According to a release from the district attorney’s office in Chester County, the drugs found on the West Chester University campus were tainted with THC, the active ingredient in marijuana.

The confections varied in size — from small hard candies, to treats the size of small oranges — and were wrapped in plastic bags.

Authorities believe the candy was meant to be sold or distributed.

“With Halloween just around the corner, the last thing we want to see is drug-laced candy hitting the streets,” said Chief Deputy District Attorney Patrick Carmody. “This was good work by the police to pick off this load of drugs before it went to college students or kids.”

Police at West Chester University began their investigation after stopping a car on campus that smelled of marijuana. After questioning the students inside the car, police worked backwards and were led to the apartment where they found the candy.

Carmody said this case is an isolated incident and that all of the tainted candy involved was seized.

“But it is a good time to remind parents to check the candy collected by their children during Halloween and to discard anything that looks suspicious," he added.

Authorities didn’t give any details on arrests and are still investigating.
