Shoppers can now buy fake urine to defeat drug tests, but Mississippi lawmakers are fighting back with what they call the "Urine Trouble" bill.

Republican Rep. Andy Gipson said synthetic human urine products are being sold in truck stops. During a meeting of a state House committee Thursday, Gipson held up what he said was an $18.99 vial of liquid that was sold just a few miles from the state Capitol. He said it contains many of the same chemicals found in human urine and is packaged with instructions on how the user can keep it at body temperature.

"I thought I had seen it all when I saw this," Gipson said.

The Mississippi Association of Self-Insurers is pushing the bill to ban fake urine. The group's director, Dan Gibson, said it's a safety concern because drug tests should accurately reveal whether truck drivers or factory workers have dangerous chemicals in their bodies.

The bill passed a committee and goes to the full House for consideration. Several states, including Arkansas, Indiana, Louisiana, New Hampshire and Oklahoma, have already banned synthetic urine.
