FLORENCE, ITALY - MAY 02: Patients smoke cannabis after the favourable vote of the bill proposed by Tuscany Region for allowing cannabis to become a legally prescribed drug for medical use on May 2, 2012 in Florence, Italy. The law proposed by the Regional Councillor of the Democratic Party Enzo Brogi passed and the Region of Tuscany will allow the use of cannabinoid substances for pain relief and end of life treatments. The purchase of cannabinoid drugs would be charged to the regional health service and be provided in health facilities and home use under medical supervision. This law signed by some members of the Democratic Party is the first law of its kind in Italy. (Photo by Laura Lezza/Getty Images)

Job applicants are testing positively for drugs at rates not seen since 2007.

According to data given exclusively to The Huffington Post by Quest Diagnostics, a medical lab research company, the rate of positive results for pre-employment urine screening increased by 5.7 percent since 2011.

“Employers are having some difficulty finding employees who can pass their drug tests,” said Dr. Barry Sample, director of science and technology for Quest.

Marijuana continues to be the drug most commonly used by American job seekers, according to Quest's data. That said, only 2 percent of the 3.4 million urine tests analyzed from the first six months of 2012 came back positive for pot. Amphetamines, the second most prevalent drug, only showed up in 0.86 percent of cases.

The drug-use results come to light just as the nation finds itself "in the midst of a serious national conversation about marijuana," according to Gil Kerlikowske, director of the Office of National Drug Control Policy. Last year, Washington and Colorado became the first states to legalize the recreational use of marijuana by adults over 21. Meanwhile, a majority of Americans were reported to support the legalization of pot, according to a poll released in December.

The Drug Enforcement Administration insisted in a January filing that marijuana legalization would promote increased drug use, HuffPost previously reported. But Sample, who said Quest has been compiling data on workplace drug tests for 25 years, said he has found no correlation in the data between states that have decriminalized or legalized the use of marijuana and positivity rates for pre-employment drug tests. Employers can still promote a drug-free work environment independent of state law, he noted.

Indeed, employers still have the right to ban drug use in the workplace, and state law does not diminish their power to do so, according to the Cleveland-based law firm BakerHostetler.

Workplace drug bans' most recent test came in September, when an appeals court in Michigan ruled that a Walmart employee who used medical marijuana was rightfully fired. Joseph Casias, an inventory worker at a Walmart in Battle Creek, Mich., was prescribed marijuana for his cancer as well as an inoperable brain tumor.

But as workers' attitudes toward drugs like marijuana shift, employers may want to rethink the wisdom of drug testing.

“Employers are going to have to take a hard look at their policies and decide if they want to do drug testing,” said Holli Hartman, counsel at BakerHostetler. "[Marijuana] is still an illegal drug on the federal level, but employers are still going to have a lot of discretion to decide what goes on in the workplace and also what their employees do outside of the workplace to some extent."
