COLORADO: As Colorado cannabis sales begin Jan. 1, one fact is sometimes overlooked: Employers still can fire workers for using it on- or off-duty.
State law gives employers full authority to impose any drug prohibitions they wish, despite it being legal in Colorado for adults to possess and consume marijuana.
“Employers hold all the cards,” said Curtis Graves, a staff attorney for the Mountain States Employers Council.
So you smoke only off-duty? Not good enough. Consuming just at home provides no protection if your workplace drug test comes back positive for marijuana.
