A Westmoreland County woman was arrested after police say her two-year-old son ingested cannabis.
Shelby Bosworth told officers Friday her two-year-old fell down the stairs.
Police say he was later taken to a hospital after he wouldn't wake up from a nap.
Tests showed the toddler didn't suffer injuries from the fall, but a urine test found the child had marijuana in his system.
Bosworth was released on $15,000 bail and is charged with endangering the welfare of a child.
