In most California jobs, you cannot be fired for smoking weed on your own time and away from work. Protections that took effect January 1, 2024 added off-duty cannabis use to the activities shielded under the Fair Employment and Housing Act. But your employer can still fire you for being impaired on the job, and several categories of workers are cut out of these protections entirely.
The Basic Rule Under California Law
Assembly Bill 2188 added Section 12954 to the California Government Code. It makes it unlawful for most employers to fire, demote, discipline, refuse to promote, or otherwise penalize you because you use cannabis off the job and away from the workplace.1California Legislative Information. California Government Code 12954
Recreational or medical, it doesn’t matter. What matters is that the use happens on your own time and somewhere other than work. Meet those two conditions and your employer can’t hold it against you.
When Your Employer Can Still Fire You
The protection has limits, and they’re real ones. Section 12954 does not give you the right to possess or use cannabis on the job, and employers can still maintain a drug-free and alcohol-free workplace.1California Legislative Information. California Government Code 12954 If you show up impaired, you can be disciplined or terminated, the same as if you showed up drunk.
Post-accident drug testing is also still allowed. OSHA’s position is that testing after a workplace incident is permissible when the purpose is investigating the root cause rather than punishing an injury report.2Occupational Safety and Health Administration. Clarification of OSHA Position on Post-Incident Drug Testing The catch is that the test itself has to comply with California’s new rules on what it measures.
Why the Type of Drug Test Matters
AB 2188 didn’t ban workplace drug testing. It banned a specific kind of positive result from being used against you. Traditional urine and hair tests pick up non-psychoactive cannabis metabolites that stay in the body for days or weeks after use. Those metabolites say nothing about whether you’re impaired right now. Under Section 12954, employers cannot penalize you based on the presence of those leftover compounds.1California Legislative Information. California Government Code 12954
If an employer wants to screen for cannabis, the law pushes them toward tests that detect the active psychoactive compound (THC) or impairment tests measured against your own baseline. In practice, this has moved most employers to oral fluid testing, which picks up active THC and gives a closer read on recent use. Blood tests also detect active THC, though they’re more invasive and less common for routine screening.
The practical takeaway: if your employer runs a standard urine panel and fires you based on a positive result for cannabis metabolites alone, that decision likely violates Section 12954. Running the test isn’t illegal. Using metabolite-only results as the reason for firing you is.
Jobs That Aren’t Protected
Several categories of workers fall outside AB 2188 entirely. If you work in one of these roles, your employer can still test for cannabis metabolites and fire you for off-duty use.
- Workers in the building and construction trades are fully exempt from the law.1California Legislative Information. California Government Code 12954
- Positions requiring a federal background investigation or security clearance under Department of Defense regulations (32 CFR Part 117) or equivalent agency rules are excluded.1California Legislative Information. California Government Code 12954
- DOT safety-sensitive positions are subject to federal drug testing rules that state law cannot override. That covers commercial truck drivers, pilots, train engineers, school bus drivers, subway operators, aircraft maintenance personnel, ship captains, and pipeline emergency response workers.3U.S. Department of Transportation. DOT Notice on Testing for Marijuana
The DOT has been explicit that its drug testing rules for safety-sensitive transportation employees don’t change based on state cannabis laws or federal rescheduling discussions.3U.S. Department of Transportation. DOT Notice on Testing for Marijuana If you hold a CDL or work any DOT-regulated role, federal rules govern.
Federal Employees and Federal Contractors
Cannabis is still a Schedule I controlled substance under federal law, and that creates a separate set of problems if your job is tied to the federal government.
Executive Order 12564 requires federal employees to refrain from using illegal drugs, on duty or off duty. “Illegal drugs” is defined as Schedule I or II controlled substances possessed unlawfully, which includes cannabis. Federal agencies test employees in sensitive positions, and can test any employee on reasonable suspicion, after a workplace accident, or as part of a rehabilitation program. Employees who use illegal drugs and refuse counseling or fail to stop face removal from federal service.4U.S. National Archives. Executive Order 12564 Drug-Free Federal Workplace
Private companies with federal contracts have their own mandate. Under the Drug-Free Workplace Act, any contractor receiving a federal contract above the simplified acquisition threshold must publish a drug-free workplace policy, run a drug awareness program, and impose sanctions on employees convicted of workplace drug offenses.5Office of the Law Revision Counsel. 41 US Code 8102 If your employer holds federal contracts, that obligation can effectively override your state protections even if you don’t personally work on the federal project.
Applying for a Job and Old Cannabis Convictions
Senate Bill 700, which also took effect January 1, 2024, extended these protections to job applicants. Employers cannot ask about your prior cannabis use on applications or in interviews.6California Legislative Information. SB 700 Employment Discrimination Cannabis Use
SB 700 also covers cannabis-related information that shows up in a criminal background check. By default, an employer cannot use it against you. There’s an exception: if the employer is allowed to consider your criminal history under California’s Fair Chance Act or another state or federal law, the cannabis-related information becomes fair game.6California Legislative Information. SB 700 Employment Discrimination Cannabis Use Even then, the Fair Chance Act requires an individualized assessment linking the conviction to the actual duties of the job before an employer can deny you the position.7California Legislative Information. California Government Code 12952
Medical Cannabis Users
If you use cannabis for a medical condition, federal disability law doesn’t add a layer of protection. The Americans with Disabilities Act excludes people who use illegal drugs, and because cannabis is still Schedule I, the ADA does not require employers to accommodate cannabis use. Courts have applied this rule consistently, including in states where medical cannabis is legal.
AB 2188 fills much of the gap at the state level. It protects medical and recreational off-duty use equally, so your employer cannot fire you for using cannabis at home regardless of whether a doctor recommended it. What the law does not do is require your employer to change workplace policies or schedules to accommodate cannabis use. It prohibits retaliation for what you do on your own time. Nothing more.
If You’ve Already Been Fired
If you believe you were fired or otherwise penalized because of your off-duty cannabis use, you can file a complaint with the California Civil Rights Department. These protections are enforced through the same FEHA framework as other employment discrimination claims.
You have three years from the date of the last discriminatory act to submit an intake form to CRD. That deadline is firm. To file, you’ll need the basic facts of what happened, your employer’s name and contact information, any relevant documents, and the names of any witnesses. Complaints can be started through CRD’s online California Civil Rights System.8California Civil Rights Department. Complaint Process
You can also skip CRD’s investigation and go directly to court, but for employment cases you must first obtain a Right-to-Sue notice from CRD before filing your own lawsuit.8California Civil Rights Department. Complaint Process That notice can be requested immediately, without waiting for an investigation.
If CRD investigates and finds reasonable cause that your employer violated the law, remedies can include reinstatement, required changes to employer policies, mandatory training, and damages for emotional distress.9California Civil Rights Department. Discrimination in Employment Use of Cannabis FAQ If you file your own lawsuit, back pay and attorney’s fees may also be available under FEHA’s broader enforcement provisions.
