California marijuana laws for employment changed on January 1, 2024, when Government Code Section 12954 took effect and added cannabis use to the protected activities under the Fair Employment and Housing Act (FEHA). Your employer generally cannot fire you, refuse to hire you, or otherwise penalize you because you use cannabis off the job and away from the workplace.1California Legislative Information. California Government Code Section 12954 The law also restricts how employers can test for cannabis. It does not protect anyone who shows up impaired, and several categories of jobs are carved out entirely.
What’s Protected Off the Clock
Section 12954 covers the full employment relationship. Hiring, promotions, discipline, and termination all fall within it. Use cannabis at home on Saturday, show up sober Monday, and your employer has no legal basis to act against you for that use.1California Legislative Information. California Government Code Section 12954
The statute also bars employers from asking job applicants about prior cannabis use. If prior cannabis-related information turns up in a background check, the employer cannot use it against you unless another state or federal law specifically allows it.1California Legislative Information. California Government Code Section 12954 Criminal history can still be considered under separate rules in Government Code Section 12952, the Fair Chance Act, but a past cannabis charge generally cannot drive the hiring decision.
Drug Testing: What Employers Can and Can’t Use
This is the piece that changes day-to-day life for most workers. Traditional urine and hair tests detect non-psychoactive cannabis metabolites, which linger in the body for days or weeks after use and tell you nothing about current impairment. Under Section 12954, an employer cannot base an employment decision on a drug test that finds non-psychoactive cannabis metabolites in your hair, blood, urine, or other bodily fluids.1California Legislative Information. California Government Code Section 12954
Employers who want to screen for cannabis have to use methods that detect active THC, the compound that actually causes impairment. Oral fluid (saliva) testing is the most common compliant option, and it detects active THC over a much shorter window than a urine test.2California Legislative Information. AB-2188 Discrimination in Employment: Use of Cannabis Impairment-based testing is another option. These tests don’t look for any chemical compound at all; they measure your current cognitive or physical performance against your own established baseline. Pre-employment screening is allowed as long as it tests for active THC rather than metabolites.
What Your Employer Can Still Do
None of this gives you the right to be high at work. The law explicitly states that Section 12954 does not permit an employee to possess, be impaired by, or use cannabis on the job.3Civil Rights Department. Discrimination in Employment: Use of Cannabis Employers can keep drug-free and alcohol-free workplace policies, and they can discipline or terminate any employee who is impaired while working, whether the cannabis use is recreational or medical.
Employers also retain the right to test after a workplace incident or when they have reasonable suspicion that an employee is impaired. Federal OSHA guidance requires that post-incident testing be tied to a reasonable belief that drug use contributed to the incident, rather than used as an automatic penalty for reporting an injury. If the circumstances point to impairment, your employer can test.
Jobs That Aren’t Covered
Section 12954 excludes three categories of workers, and if you fall into one of them the off-duty protections do not apply at all.1California Legislative Information. California Government Code Section 12954
- Building and construction trades. The legislature excluded these workers due to the physical dangers of the work.
- Positions requiring a federal background investigation or security clearance under Department of Defense regulations or equivalent federal agency requirements.
- Positions where state or federal law requires controlled substance testing as a condition of employment, federal funding, federal licensing benefits, or a federal contract.
That last category is broader than it sounds. Department of Transportation safety-sensitive positions, including commercial truck drivers, airline crew, pipeline workers, and transit employees, still have to undergo drug testing under federal rules. Federal contractors above the simplified acquisition threshold have to maintain drug-free workplace programs under the Federal Acquisition Regulation, which can include testing for any controlled substance on federal schedules. Cannabis remains on those schedules.4Acquisition.GOV. Subpart 26.5 – Drug-Free Workplace If you work in any of these positions, California’s off-duty protections do not apply.
Medical Cannabis Patients
Section 12954 protects “the person’s use of cannabis” without distinguishing between medical and recreational use.1California Legislative Information. California Government Code Section 12954 If you have a medical cannabis recommendation, your off-duty, off-site use is protected the same way any adult’s recreational use is. That reverses the practical outcome of the 2008 California Supreme Court decision in Ross v. RagingWire Telecommunications, which held that FEHA did not require employers to accommodate medical cannabis use.
No employer is required to let you use, possess, or be impaired by cannabis at work, even for medical reasons. Cannabis is still a federally controlled substance, so the Americans with Disabilities Act does not require accommodation of its use. FEHA does require employers to engage in a good-faith interactive process to find reasonable accommodations for the underlying medical condition behind a cannabis recommendation.5California Legislative Information. California Government Code Section 12940 That accommodation might include modified schedules or ergonomic changes, but it cannot involve on-the-job cannabis use, and the employer does not have to grant it if doing so would cause undue hardship.6Civil Rights Department. Reasonable Accommodation
If Your Employer Violates the Law
If an employer fires you, refuses to hire you, or otherwise penalizes you for off-duty cannabis use, you can file a complaint with the California Civil Rights Department (CRD). You have three years from the date of the discriminatory act to file.7California Legislative Information. California Government Code Section 12960 Once that deadline passes, the claim is gone.
You can start by submitting an intake form through the CRD online portal; a representative conducts an intake interview, and if your complaint qualifies, CRD prepares a formal complaint and sends it to the employer.8Civil Rights Department. Complaint Process Alternatively, you can skip the CRD investigation and file your own lawsuit. To do that, you first request a Right-to-Sue notice. Once you receive it, you have one year to file.9Civil Rights Department. Obtain a Right to Sue Requesting the notice means CRD will not investigate your complaint. It’s one path or the other.
A successful FEHA claim can produce back pay, front pay, reinstatement or hiring into the wrongfully denied position, emotional distress damages, punitive damages in cases of especially egregious employer conduct, and attorney’s fees and costs at the court’s discretion. The fee-shifting provision matters because it’s what lets many employment attorneys take FEHA cases on contingency. A prevailing employer can only recover fees if the court finds your lawsuit was frivolous or groundless, so the risk of filing a good-faith claim is relatively low.10California Legislative Information.
