Testing Process
Urine drug testing begins with the collection process, where an individual provides a urine sample, usually in a secure location following strict chain of custody protocols. Once the urine sample arrives at the laboratory, the sample will go through an initial screening, which is a rapid immunoassay test to screen for drug metabolites. If any samples show a presumptive positive result, the next phase of testing is confirmation testing, This requires the urine sample to under go GC/MS or LC/MS Confirmation testing, which provides a secondary testing method to ensure an accurate and legally defensible result. The last phase of the urine drug testing process should include Medical Review Officer (MRO) verification, which is required for Federal Drug Testing, but should also be used in NON DOT Urine Drug Testing as well. An MRO will review all verified positive laboratory results and considers any legitimate medical explanations the donor may have.

Drug Testing Statistics in the USA

Drug testing in the US workforce has seen fluctuations in positivity rates and drug-specific trends in recent years. Here is a look at some keys statistics:

Overall drug test positivity
Historically High Rates: Overall drug positivity in the general US workforce has remained at historically high levels, with rates around 4.6% in 2021 and 2022, and 5.7% in both 2022 and 2023. This is the highest level in over two decades, up significantly from lows of 3.5% in 2010-2012. Tampering on the Rise: The percentage of employees attempting to subvert the drug testing process through tampering with specimens (substituted or invalid samples) has surged. Substituted urine specimens increased by over 600% in 2023 compared to the prior year, reaching the highest rate ever reported. Invalid urine specimens also increased by 45.2%.

Marijuana Use
Continued Upward Trend: Marijuana positivity rates have consistently climbed, reaching their highest levels ever recorded in both the general workforce and post-accident tests. Impact of Legalization: In states where recreational marijuana is legal, the positivity rate for marijuana in the general workforce was significantly higher (5.7% in 2022) than the national average (4.3% in 2022). However, marijuana positivity decreased in the federally mandated, safety-sensitive workforce, potentially due to the deterrent effect of expected drug testing in those roles. Post-Accident Positivity Soars: Post-accident marijuana positivity in the general workforce reached a 25-year high in 2022 and continues to climb, showing a 114.3% increase between 2015 and 2023.

Other Drugs
Amphetamines: Positivity for amphetamines has shown an upward trend, increasing by a fifth of a percentage point from 2021 to 2022, particularly among employees in the Education Services industry. Note that testing does not distinguish between legally prescribed and illicit use. Opiates: Overall positivity for opiates (codeine/morphine) in the general workforce has decreased over the last five years. Heroin and other opiates also showed decreases in positivity rates. Cocaine: Cocaine positivity in the general workforce showed a slight increase in 2022 but has declined over the past five years.

Workplace Drug Testing Landscape
Commonality: Roughly 63% of organizations conduct some form of alcohol or drug testing, a figure that has remained relatively stable over the years. Testing Methods: Urine tests are the most common, used by about 85% of companies, followed by saliva and hair tests. Industry Variation: The prevalence of drug testing varies across industries. Government positions, healthcare, and transportation are among the most likely to require drug tests. Note: These statistics primarily focus on workplace drug testing and may not fully represent drug use across the general population. Data collection and reporting methods may also vary between organizations.
