State Testing Policy

General Information

Allows employers to conduct drug tests for various reasons, including pre-employment, reasonable suspicion, and post-accident testing. While marijuana use is legal in the state, it does not prevent employers from enforcing drug-free workplace policies, and testing positive for THC can still affect employment decisions.

Remember, establishing robust documentation is a key risk mitigant for employers in states like Colorado.

Safety-Sensitive Positions
Federal law mandates testing for workers in safety-critical roles like transportation or defense sectors. Additionally, a comprehensive drug and alcohol policy for state employees exists, influenced by federal guidelines, executive orders, and state legislation.
Privacy Laws
Require that test results be kept confidential and disclosed only to individuals with a legitimate need to know. Employees must be informed of and consent to testing procedures and must respect legal protections for medical marijuana use, though they can enforce drug-free policies in safety-sensitive positions.

Recommended Procedures

Does the state have recommended procedures?

It is always recommended to have standardized documentation and training procedures and regular employee evaluations to set clear performance expectations.

Colorado does not have a state-mandated program specifically requiring employers to implement workplace impairment programs. Employers are encouraged to develop their own policies and procedures to address impairment. These policies should align with state laws, including those related to marijuana use, and follow best practices for maintaining a safe and compliant workplace.

State Employee Procedures and Policies
The Workplace Impairment Program requires a clear policy defining impairment, procedures for addressing it, and testing protocols, along with mandatory training for supervisors and employees. Testing must be conducted confidentially and in line with state regulations, while thorough documentation and adherence to legal standards, including those related to medical marijuana.

Protections for Use Outside Workplace/Work Hours

Is Colorado a "Right to Weed State"?
Employers can enforce drug policies and take action if an employee tests positive, particularly if it impacts job performance or safety. Medical marijuana patients have some protections, but these do not fully prevent employment actions.
