Today, in some industries, taking a drug test is as routine as filling out a job application.
In fact, workplace drug testing is up 277 percent from 1987—despite the fact that random drug testing is unfair, often inaccurate and unproven as a means of stopping drug use.
But because there are few laws protecting our privacy in the workplace, millions of American workers are tested yearly—even though they aren’t suspected of drug use.
Employers have the right to expect workers not to be high or drunk on the job. But they shouldn’t have the right to require employees to prove their innocence by taking a drug test.
That’s not how America should work.
Invasion And Error
However routine drug tests have become, they’re still intrusive. Often, another person is there to observe the employee to ensure there is no specimen tampering. Even indirect observation can be degrading; typically, workers must remove their outer garments and urinate in a bathroom in which the water supply has been turned off.
The lab procedure is a second invasion of privacy. Urinalysis reveals not only the presence of illegal drugs, but also the existence of many other physical and medical conditions, including genetic predisposition to disease—or pregnancy. In 1988, the Washington, D.C. Police Department admitted it used urine samples collected for drug tests to screen female employees for pregnancy—without their knowledge or consent.
Furthermore, human error in the lab, or the test’s failure to distinguish between legal and illegal substances, can make even a small margin of error add up to a huge potential for false positive results. In 1992, an estimated 22 million tests were administered. If five percent yielded false positive results (a conservative estimate of false positive rates) that means 1.1 million people who could have been fired, or denied jobs because of a mistake.
“I waited for the attendant to turn her back before pulling down my pants, but she told me she had to watch everything I did. I am a 40-year-old mother of three: nothing I have ever done in my life equals or deserves the humiliation, degradation and mortification I felt.”
From a letter to the ACLU describing a workplace drug test.
Tests That Fail
Claims of billions of dollars lost in employee productivity are based on guesswork, not real evidence.
Drug abuse in the workplace affects a relatively small percentage of workers. A 1994 National Academy of Sciences report found workplace drug use “ranges from a modest to a moderate extent,” and noted that much of reported drug use “may be single incident, perhaps even at events like office parties.”
Furthermore, drug tests are not work-related because they do not measure on-the-job impairment. A positive drug test only reveals that a drug was ingested at some time in the past. Nor do they distinguish between occasional and habitual use.
Drug testing is designed to detect and punish conduct that is usually engaged in off-duty and off the employer’s premises—that is, in private. Employers who conduct random drug tests on workers who are not suspected of using drugs are policing private behavior that has no impact on job performance.
Far From Foolproof
Sometimes drug tests fail to distinguish between legal and illegal substances. Depronil, a prescription drug used to treat Parkinson’s disease, has shown up as an amphetamine on standard drug tests. Over-the-counter antiinflammatory drugs like Ibuprofen have shown up positive on the marijuana test. Even the poppy seeds found in baked goods can produce a positive result for heroin.
About Safety-Sensitive Occupations
Alertness and sobriety are, of course, imperative for certain occupations, such as train engineers, airline pilots, truck drivers and others. Yet even in these jobs, random drug testing does not guarantee safety. Firstly, drug-related employee impairment in safety-sensitive jobs is rare. There has never been a commercial airline accident linked to pilot drug use. And even after a 1994 Amtrak accident in which several lives were lost, investigators discovered the train engineer had a well known history of alcohol, not drug, abuse.
Computer-assisted performance tests, which measure hand-eye coordination and response time, are a better way of detecting whether employees are up to the job. NASA, for example, has long used task-performance tests to determine whether astronauts and pilots are unfit for work—whether the cause is substance abuse, fatigue, or physical illness.
Drug tests don’t prevent accidents because they don’t address the root problems that lead to substance abuse. But good management and counseling can. Employee assistance programs (EAPs) help people facing emotional, health, financial or substance abuse problems that can affect job performance. EAP counselors decide what type of help is needed: staff support, inpatient treatment, AA meetings, and the like. In this context, the goal is rehabilitation and wellness—not punishment.
Employers need to kick the drug test habit.
