JACKSONVILLE, F.L.--Police say a 4-year-old boy tested positive for cocaine because he thought he was eating cake icing. 

Cops responded to a hotel room in Jacksonville after receiving a complaint about prostitution.  Once they arrived they found the child and two men in the room. 

The child tried to eat something white off the floor but police stopped him.  The white substance was cocaine. 

Police said there was also a tube of white icing on the floor so the kid probably thought the cocaine was icing. 

The child was taken to a local hospital.  Police arrested the boy's mother and the two men in the hotel room.
