Study: Medical marijuana changes how employees use sick time

“Fact #1: Legalizing marijuana is bad for the workplace.”

That’s the stark warning from the Institute for a Drug-Free Workplace, a nonprofit that works to combat drug use among American employees.

“The impact of employee marijuana use is seen in the workplace in lower productivity, increased workplace accidents and injuries, increased absenteeism, and lower morale,” the institute writes. “This can and does seriously impact the bottom line.”
