A top scientist for the FBI says the money you're carrying in your wallet is probably contaminated by cocaine.
Thomas Jourdan, chief of materials and devices at the FBI laboratory in Washington, D.C., says 85 percent to 90 percent of the currency in the United States has measurable amounts of cocaine. "A new bill is kind of a wall-to-wall sticky surface in a microscopic sense," Jourdan said. "And over the course of that bill's life, it gets things to adhere to it as well as drugs of abuse."
Everyone's money is likely tainted -- even those who've never seen crack or powder cocaine in their lives.
