A deadly new drug has hit the Big D. And so far, officials say it's responsible for 18 deaths.
It's called "cheese" and it's made from black tar heroin and Tylenol P-M tablets. Dallas authorities say it sells for about $2 a dose and can be snorted or injected. The deadly concoction has been found in Dallas schools among students as young as 11 years old. Through February, more than 120 teens have been arrested in Dallas for "cheese."
