Robert Callis-Keiser, 25, of Johnstown, Pa., faces a number of drug charges including possession of a controlled substance with intent to distribute.
The candy was found a few days before Halloween, but Callis-Keiser was only recently arrested because investigators were awaiting test results on the candy.
Police say Callis-Keiser made hundreds of pieces of the drug-laced candy in varying sizes and wrapped them for sale in his apartment.
Authorities say they discovered the stash after Callis-Keiser was allegedly caught with marijuana in his parked car.
An officers asked Callis-Keiser to search his apartment and, once inside, found containers of the candy in individual bags.
Callis-Keiser allegedly verbally confirmed to the officer that the candy was laced with THC, the active ingredient in marijuana.
Callis-Keiser has been released on $25,000 bail. Officials said he is no longer enrolled at West Chester University.
