Marijuana legalization "would reduce productivity of a significant segment of our workforce"

Yesterday, the Institute for a Drug-Free Workplace released a statement opposing the ballot initiatives in Washington, Colorado, and Oregon that would legalize marijuana.  According to their press release:

• "Those who engage in illicit drug use are one-third less productive according to a Department of Health and Human Services report."

• "With the economy the #1 issue facing our country and the #1 issue in this election, enacting laws that would reduce productivity of a significant segment of our workforce by one-third would further undermine our economy and impede recovery." 

• "Legalization would mean more use, and more use would mean a greater detrimental impact on the workplace, less productivity, and a less safe working environment for millions of American workers."

•  . . . those who engage in illicit drug use are 3.6 times more likely to be involved in a workplace accident that injures themselves and/or another person or people."
