Workplace Drug Testing

drug testingDrug testing has become a routine part of the job in many industries these days. In the past 30 years, in fact, drug testing has risen by nearly 300%. But is such testing accurate? With over 22 million tests being administered in this country every year, even a 5% false positive rate could result in over one million people’s lives being impacted in a negative way. Furthermore, are workers’ rights to privacy in the workplace being protected? If you feel your rights have been violated due to drug testing, an employment attorney may be able to help.

Drug Testing And False Positives

Recent studies indicate that 5-10% of drug tests produce false-positive results. Poppy seeds—even just a teaspoon—can produce a positive test for opioids, even three days after consumption. Prescription antidepressants and cold medicines can indicate amphetamines or benzodiazepine, and HIV medications can indicate that marijuana is in the bloodstream. Even ibuprofen has been connected with positive results for marijuana.

Drug Testing is Intrusive

Testers worry about potential tampering with test samples. That sometimes leads them to observe the employee, or to remove the sample provider’s outer attire and collect the urine sample in a room in which the water has been turned off.  For many, this experience is degrading and invasive.

Once the sample hits the lab, testing may reveal much more than the presence of illegal substances. Some legal drugs may be in the sample, and human error may make the distinction between legal and illegal substances difficult. False positives are a real possibility. Additionally, pregnancy or the genetic predisposition to diseases may also be detected. Sound impossible?  Unfortunately, there are documented cases in which this has occurred.

Systematic Errors with Drug Testing

While no one would argue that a safe workplace is not in in the best interests of employers and employees alike, many employers simply do not have sound practices in place when it comes to drug testing.

  • Random Testing: If the selection process for employees chosen for testing is not truly random, it may be discriminatory. In California, random testing is only allowed under narrow circumstances.
  • Legal Compliance: The law allows for testing of employees under reasonable suspicion of drug use only if objective facts are in evidence. Barring a good reason, singling out someone for testing is not lawful. Employers need to be aware of specific laws carved out by various municipalities or by other authorities in particular industries.
  • Uneven Implementation: One study indicates that just over 20% of respondents conducted drug testing on workers after employment. If policies are not administered uniformly, employees may have reason to suspect discrimination.
  • Medical Marijuana: While marijuana has been approved for medicinal purposes in California, it is still considered a schedule one drug at the federal level. Employers may have a zero-tolerance policy for marijuana, even though it is legal in the state.
