“Given the tight labor market, and legal recreational marijuana up and down the Left Coast, these reports are a bit surprising,” they write. “It may be that the pool of available applicants has shifted; that individuals who can pass drug test already have a job. It may be for insurance‐related reasons that employers are ensuring they have a drug‐free workplace, even if it means monitoring their employees behavior on their own time. However it is possible that these anecdotal reports reflect a broader increase in drug usage that would be both an economic and societal problem.”
