This hot-selling product is a fake ... and that's exactly why buyers want it. Sales of synthetic urine — which people can use to cheat on drug tests — appear to be on the rise in the United States, according to news reports. And the substance has become such a problem that some states are moving to ban it. According to The Washington Post, Indiana and New Hampshire passed laws last year banning synthetic urine, and two additional states — Missouri and Mississippi — introduced bills this year to make the product illegal. "Our employers are reporting to us a concern that more and more of their employees are using synthetic human urine to cheat on a drug test," Dan Gibson, executive director of the Mississippi Association of Self-Insurers, which has lobbied for the bill in Mississippi, told The Washington Post. Mississippi State Rep. Willie Bailey said at a hearing that fake urine is a "hot seller" at truck stops, the Post reported. "They can't keep it in stock," Bailey said. Synthetic urine is made from a mix of chemicals, with some manufacturers saying their products contain uric acid, the Post reported. (Uric acid is a chemical found in human urine.) The fake urine sells for $17 to $40 and can be bought online or in certain stores, such as some head shops. Originally published on Live Science. Source
