State Testing Policy

General Information
Effective January 1, 2024, California Assembly Bill 2188 limits employers from using urine tests for cannabis metabolites to make employment decisions and shifts focus to tests that better indicate current impairment, such as oral fluid or blood tests. Employers can still conduct drug tests based on reasonable suspicion of impairment but must follow these new legal standards.
Safety-Sensitive Positions
In California, with safety-sensitive positions, under AB 2188, employers must use testing methods that reflect current impairment, not just urine tests for cannabis metabolites, even for safety-sensitive roles.
Privacy Laws
Pre-employment drug testing can occur upon a job offer, but they must detect only active, psychoactive THC, not inactive metabolites. January 2024, employers cannot discriminate based on off-duty, off-site cannabis use.

Recommended Procedures

Does the state have recommended procedures?
It is always recommended to have a standardized documentation procedures and regular employee evaluations to set clear performance expectations. Employers can't discriminate based on off-duty cannabis use, they can implement pre-employment tests that detect only active THC. For existing employees, testing is restricted to situations with reasonable suspicion of impairment or specific requirements like safety-sensitive positions. Resources like confidential employee assistance programs (EAPs) are encouraged to address personal issues that might impact workplace safety.
State Employee Procedures and Policies
California recommends that private employers create a clear, written drug testing policy covering preemployment, random, post-accident, and reasonable suspicion testing. Employers should use methods that accurately reflect current impairment, such as oral fluid or blood tests, and apply the policy consistently to avoid discrimination, ensuring confidentiality and legal compliance.

Protections for Use Outside Workplace/Work Hours

Is California a "Right to Weed State"?
A new California law will prevent most employers from punishing workers who use cannabis away from the job. Employees who are impaired at work can face repercussions, but, in most cases, a mere positive drug test for marijuana will not be a serious issue when the law was implemented in January 2024.
