A highly addictive drug known as "cheese heroin" is a blend of black tar Mexican heroin and over-the-counter cold medication, such as Tylenol PM. The drug costs only a couple of dollars a hit and children as young as 9, hooked on cheese heroin, have been rushed to hospital emergency rooms for heroin withdrawal. The combination of the two drugs can cause vital body functions such as breathing and heartbeat to slow down and result in death.
