The rate of positive drug tests among employees is up for the first time since 2003, mostly because of the legalization of recreational marijuana, according to Quest Diagnostics Employer Solutions. Marijuana positive rates across the general workforce in the U.S. increased 5% between 2012 and 2013. Positive rates rose 20% in Colorado and 23% in Washington, both states where marijuana was legalized in 2012. Employers in all 50 states may impose sanctions on employees who test positive for marijuana.
