Many companies believe the drug testing myth that a Random Testing program isn’t necessary if a Pre-Employment testing policy is in place. This is a common misconception among companies and business owners. According to the 2013 National Survey on Drug Use and Health, approximately 10 percent of full-time workers are substance abusers. 68.9 percent of the estimated 15.4 million drug users in the United States are employed either full-time or part-time. Some of these individuals may have been able to manipulate their usage patterns to avoid detection or to adulterate the specimen that they give during the Pre-Employment test. Random testing programs offer a deterrent for employees to choose to make a bad decision. While random testing might not always deter addicts, it offers organizations a means to detect use. The most obvious benefit of a Random Test is the deterrent value. The employee does not know when the test is going to take place. Random testing can prevent dishonest employees from avoiding, diluting, or substituting their specimens.
