Cannabis and Workplace Accidents

Urine drug test materials
The use of cannabis is not positively associated with workplace accidents, according to a clinical study published in the Journal of Addictive Diseases.

Researchers examined whether there exists a statistical association between cannabis consumption and work-related accidents by comparing the proportion of marijuana positive urine specimens for post-accident verses random samples from individuals in five states: Indiana, Ohio, Pennsylvania, Kentucky and Missouri.

“This study failed to demonstrate a statistically significant difference between the numbers of laboratory positive marijuana urine drug tests for a group of random drug tests compared to a group of post-accident drug tests,” according to the study’s author. “This study cannot be taken as definitive evidence of absence of an association between marijuana and work related accidents but the findings are compelling.”

A 2010 study of 20 years of published literature on cannabis drug testing and workplace performance came to this conclusion: “Urine tests have poor validity and low sensitivity to detect employees who represent a safety risk; … [and] urinalysis has not been shown to have a meaningful impact on job injury/accident rates.”
