It’s no secret that drug abuse in the workforce is a growing challenge for American businesses. A Baltimore food-processing plant practices a zero-tolerance policy in which one randomly chosen employee gets tested each month. It is costly to hire a third-party company and pay the clinic to conduct the test, but the business is certainly not a good place to be intoxicated. According to the National Safety Council, 57 percent of employers say they drug test employees. And with opioids killing about 33,000 Americans in 2015, federal government employees who use drug tests will be required to submit to a more extensive screening. The opioid crisis has caused hiring difficulties, a slowing economy for the country, and dangerous alternatives to painkillers.
