Overview

Despite being one of the first states to legalize recreational cannabis in 2012, Colorado provides no statutory employment protections for cannabis users. The Colorado Supreme Court ruled in Coats v. Dish Network (2015) that employers can terminate employees for off-duty cannabis use because it remains federally illegal and thus is not a 'lawful activity' under the state's lawful off-duty conduct statute. Employers maintain full discretion to test, discipline, and terminate employees for cannabis use.

Key Facts

Federal Considerations

Regardless of Colorado's state laws, federal employees and contractors are subject to federal drug-free workplace requirements under Executive Order 12564 and the Drug-Free Workplace Act of 1988. Workers in DOT-regulated industries (trucking, aviation, rail, transit, pipelines, maritime) must comply with federal testing requirements. Safety-sensitive positions in healthcare, law enforcement, and the military are also exempt from state protections.
