The Drug Testing Index, published by Quest Diagnostics, is a report published annually regarding the rate of drug usage, revealed by positive drug test results, within the workplace. The results are based on ten million drug test results. Some major findings include:
- The percentage of positive drug test results for marijuana, cocaine and methamphetamine has risen for the second year in a row.
Unlike results in 2013, positive drug tests for marijuana increased at the same rate in Colorado and Washington as the rest of the United States in 2014.
Positive drug tests for amphetamines, specifically methamphetamine, have continued to show a steady increase.
The drug test positivity rate for a marker of heroin, called 6-AM, doubled in the United States workforce between 2011 and 2014.
There is speculation that prescription opiates have become too expensive, which has turned people to the use of heroin. In addition, companies are debating re-enacting strict substance abuse programs to manage this growing issue.
