Overview

California enacted AB 2188 (effective January 1, 2024), which provides significant employment protections for cannabis users. The law prohibits employers from discriminating against employees or applicants based on off-duty cannabis use or the presence of non-psychoactive cannabis metabolites in drug tests. Employers can still test for THC using methods that detect current impairment but cannot rely on tests that only detect past use. Exceptions exist for building and construction trades, federal government positions, and roles requiring federal background checks.

Key Facts

Federal Considerations

Regardless of California'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.

Frequently Asked Questions

Can California employers still drug test for cannabis?+
Yes, but with restrictions. Under AB 2188, employers cannot use tests that detect non-psychoactive cannabis metabolites (like standard urine tests for THC-COOH). They must use tests that detect active THC or current impairment.
Does AB 2188 protect on-the-job cannabis use?+
No. AB 2188 only protects off-duty, off-site cannabis use. Employers can still prohibit cannabis possession, use, and impairment during work hours and on company premises.
Who is exempt from California's cannabis employment protections?+
Employees in building and construction trades, federal government employees, positions requiring federal background checks or security clearances, and employees subject to federal testing requirements (DOT, etc.) are exempt.
