According to Quest, the increase was “largely driven by double-digit increases in marijuana positivity.” In fact, according to the report, in 2015 there was a “25 percent relative increase in marijuana detection as compared to 2014.” The report also showed a significant increase in heroin positivity in urine tests for federally mandated safety-sensitive employees.
Another disturbing trend is the rising positivity rate for post-accident urine drug testing in both the general U.S. and the federal mandated, safety-sensitive workforces. According to the index, post-accident positivity increased 6.2 percent in 2015, compared to 2014, and increased a whopping 30 percent since 2011.
To those of us who have warned about the growing liberalization of the use of marijuana, from so-called “medical marijuana” to recreational abuse of the Schedule I drug, the results of the index are all too predictable. It is also not surprising that none of the major organizations that push for pot legalization and decriminalization of marijuana have written major stories about the Quest Diagnostics report.
The more people use marijuana, the more likely it is that those who work and are subject to testing will pop positive for marijuana, even in safety-sensitive jobs. Think about that next time you hop on an airplane, ride Amtrak, or go about your daily life thinking everyone is focused on their job and your safety.
