On September 18, 2022, California amended its primary employment discrimination law to specifically regulate the drug testing methodologies that employers may use when making hiring, termination, and other employment decisions relating to cannabis users. More recently, on May 9, 2023, Washington Governor Jay Inslee signed similar legislation relating to initial hiring decisions. Both laws, which will be effective January 1, 2024, are the first of their kind because they require employers to have a basic understanding of a somewhat complicated issue – the science behind cannabis testing.
Testing for THC
The primary psychoactive agent – the thing that gets people high – in cannabis is delta-9-tetrahydrocannabinol (THC). At present, most employers use urine drug tests, which target the cannabis metabolite THCA, which is nonpsychoactive. Thus, when an employer receives a urine test result, all the employer knows is that the person has used cannabis at some time in the recent past (from days to several weeks); exactly when, however, is unknown. THC is the primary target and is found in greater concentrations in drug tests that use saliva specimens, which in turn leads to test results that are tied to or related to psychoactive effect. None of the scientifically valid drug tests, including those that use saliva specimen, inform an employer whether a person is impaired at or near the time they provide a specimen for testing.California’s AB 2188
On September 18, 2022, California Governor Gavin Newsom signed AB 2188, which amended the Fair Employment and Housing Act (FEHA) to essentially make cannabis users a protected class in California. Effective January 1, 2024, it will be unlawful for most employers to discriminate against a person in connection with hiring, termination, or another employment decision if the discrimination is based upon either:(1) The person’s use of cannabis off the job and away from the workplace. This paragraph does not prohibit an employer from discriminating in hiring, or any term or condition of employment, or otherwise penalize a person based on scientifically valid preemployment drug screening conducted through methods that do not screen for nonpsychoactive cannabis metabolites.
(2) An employer-required drug screening test that has found the person to have nonpsychoactive cannabis metabolites in their hair, blood, urine, or other bodily fluids.
There are several exceptions to the new employment discrimination prohibitions: (1) employees in the building and construction trades; (2) applicants or employees hired for positions that require a federal government background investigation or security clearance in accordance with Department of Defense regulations, or equivalent regulations applicable to other agencies; and (3) applicants and employees required to be tested under state or federal laws and regulations or as a condition of an employer receiving federal funding or federal-licensing benefits or entering into a federal contract. What does this mean? Subparagraph (2) focuses solely on the type of test. More specifically, employers cannot take an adverse employment action against an applicant or an employee based on a drug test that targets nonpsychoactive cannabis metabolites. As explained above, this effectively makes urine tests useless (and unlawful) to California employers. As a result, covered employers who wish to test for cannabis should consider discontinuing urine testing on or before January 1, 2024, regardless of whether the test is for a job applicant or a current employee. What about saliva/oral fluids testing? The answer seems to depend on whether the test is for a job applicant or a current employee. Subparagraph (1) states that an employer can reject a job applicant if the cannabis test does not screen for nonpsychoactive metabolites, suggesting that an employer can rely on a pre-employment saliva/oral fluids test that targets the parent drug THC. The same may hold true for hair testing. However, even if an employer uses a saliva/oral fluids test for a current employee that complies with subparagraph (2), it still must consider the first sentence of subparagraph (1), which prohibits employers from taking action against someone because of their “use of cannabis off the job and away from the workplace.” Oral fluids tests might provide a close-in-time correlation as to when employees use cannabis, but they do not prove that employees actually are impaired or used cannabis on the job or at work. As a result, even if an employer uses a lawful testing methodology for a current employee, an employer that takes action against an employee for cannabis use still has significant risk under FEHA because it likely will be difficult to rebut the employee’s assertion that they used “off the job and away from the workplace.”
