This is the third year in a row that the state has taken top honors.
The index is compiled from more than 10 million drug tests administered in workplaces across the U.S.
A chart-topping 4.64 percent of Oregon’s drug tests in 2017 were positive for marijuana. That’s up from 2016’s 4.5 percent and 2015’s 3.43 percent. Can Oregon set a new record next year?
Other states with legal weed are further down the list. Massachusetts came in at a respectable third, with 3.56 percent of tests coming back as positive. Washington state came in sixth, with 3.18 percent. Nevada and Colorado were eighth and tenth, respectively; both were just under 3 percent.
“At least anecdotally. More firms are reporting trouble finding workers who can pass a drug test,” Oregon economists told Willamette Week earlier this year.
