LATROBE, Pa. -- A Westmoreland County man faces charges for allegedly giving a marijuana-laced cookie to a co-worker.

Ronald L. Thompson, 50, of Latrobe, gave the cookie to a 64-year-old woman during a work break at Westmoreland Plastics last month, Latrobe police said.

The woman said she had no idea there was marijuana baked inside the cookie.

She told police that she became ill and disoriented when she left work. She drove around for a while, then parked her car and called for help, and was treated at a hospital for a marijuana overdose, police said.

Police searched Thompson's apartment and found four more marijuana cookies, a small amount of marijuana and drug paraphernalia.

Thompson faces charges of possession and possession with intent to deliver.
