By the Numbers: Random Drug Testing Data

by Ashlyn Hazard on September 22, 2017

Companies drug test their applicants and employees at a variety of times, for a variety of reasons, using a variety of specimen types. The federally-mandated, safety-sensitive sector follows regulatory drug testing guidance and in doing so establishes a model that is frequently followed by U.S. companies who elect to perform drug testing because they see its value.

Starting on January 1, 2016, this regulatory guidance changed for the U.S. Department of Transportation’s (DOT) Federal Motor Carrier Safety Administration (FMCSA) when the minimum annual random urine drug test rate was decreased from 50% to 25%. This change was made because drug test positivity rates among this sector remained at less than 1% for three consecutive years.

Many FMCSA employers, including two-thirds of Quest Diagnostics FMCSA clients, followed this guidance and decreased their random testing rate throughout 2016. We recently analyzed more than 30 months of Quest Diagnostics FMSCA drug testing data – including the 12 months prior to the change and 18 months after it – in an effort to better understand the relationship between the rate of random drug tests performed and the corresponding rate of drug positivity in these tests. It is worth noting that while the federal panel is made up of amphetamines, cocaine, marijuana, opiates, and PCP, we removed amphetamines and opiates from our analysis. These two drug classes have a greater chance of being used with a valid prescription and overturned by a Medical Review Officer. Excluding these drugs ensures the positivity data is conservative in nature. We found these insights to be the most telling:

From the start of 2015 to the first half of 2017, Quest Diagnostics FMCSA clients decreased their random testing volume by an average of 25%. During that time, the average positivity of the random drug tests in this testing population increased by 13%. Over the same time period, these clients increased their testing by an average of 6% for all other testing reasons such as pre-employment, and only experienced a 2% average increase in positivity.

Simply stated, as the random drug testing rate declined, so has the chance and risk of being tested. As the risk of being tested declined, so did the power of drug testing and its ability to help deter use. With this in mind, it’s not surprising that drug use is increasing among long-haul truckers, bus drivers, delivery drivers, and construction vehicle drivers. In turn, every vehicle and person these drugged drivers interact with on the road bears an increased risk of an accident.

Two logical questions stem from this analysis:

Q: When will the required random testing rate be increased?

A: Only time will tell. Unfortunately, things have to get worse before they’ll get better, as the entire FMCSA random testing population must once again climb back to more than 1% positivity before we can expect to see a change in the regulation.

Q: What can FMCSA employers do to minimize the potential negative impact on their organizations, employees, and the general population?

A: For now, employers can remain vigilant in drug testing. The FMCSA random rate is only a minimum standard and employers can always elect to drug test at a greater rate than the minimum requirement. Take the time to examine your testing and positivity data, keep the dissuasive power of random drug testing in mind, and carefully consider the associated risk that your organization is willing to bear.

America’s Favorite Illicit Drug: Marijuana

by Nicole Jupe on July 7, 2017

america's favorite drug is marijuanaMarijuana is the product of the hemp plant, Cannabis sativa, containing the psychoactive chemical delta-9-tetrahydrocannabinol (THC). Despite its illegal status, the drug reigns as America’s favorite and most commonly detected illicit drug. Since the 1920s, marijuana has been the subject of myths and propaganda while also being glamorized by pop culture, movies, and television. Attitudes relaxed in the 1960s and the drug gained popularity among the upper middle class and with counter-culture movements like Woodstock. Experimentation and widespread marijuana use followed. Thirty years later, voters passed Proposition 215 in 1996 and California became the first state to allow the medical use of marijuana. Today 30 states and the District of Columbia have their own versions of marijuana legislation; however, it remains a Schedule I Controlled Substance under Federal law.

Marijuana positivity continues to trend upward. The latest Quest Diagnostics Drug Testing Index™ (DTI) data indicates that marijuana use has increased significantly in the last three years. Among the federally-mandated, safety-sensitive workforce, which only utilizes urine testing, marijuana positivity increased nearly 10% (0.71% in 2015 versus 0.78% in 2016), the largest year-over-year increase in 5 years. In the general U.S. workforce, marijuana positivity climbed in urine testing (2.4% in 2015 versus 2.5% in 2016) and hair testing (7.0% in 2015 versus 7.3% in 2016). The most remarkable data pointed to a nearly 75% increase of marijuana positivity in oral fluid drug tests in the general U.S. workforce in the last 3 years (5.1% in 2013 to 8.9% in 2016).

Quest has also been analyzing data for several years in states that have passed medical and recreational marijuana use statutes. “2016 is the first year since Colorado and Washington approved recreational use that the rates of year-over-year change were sharply higher than the national average,” said Barry Sample, PhD, Senior Director of Science and Technology, Quest Diagnostics Employer Solutions.

Globally, there are 182.5 million cannabis users, or 3.8% of the total population, according to the World Drug Report. Not surprisingly some employers report difficulty in finding job applicants who can pass a drug test. The most current findings for the United States from the National Survey on Drug Use and Health tell us:

  • An estimated 22.2 million adults, 8.3% of the total population, aged 12 or older currently use marijuana. The increase in marijuana use among people aged 12 or older reflects the increase in marijuana use by adults aged 26 or older.
  • About 1 in 5 young adults aged 18 to 25 (19.8%) were current users of marijuana.
  • Approximately 651,000 adolescents (ages 12-17), 1.8 million young adults, and 1.6 million adults suffer from a marijuana use disorder, pointing to dependence and recurrent use that affects health, responsibilities at work, home, or school.

That said, research and data indicates that marijuana use in society is up. Drug testing continues to be an important tool to maintain a safe, healthy, and productive drug-free workplace.
