As of October 14, 2026, most California employers cannot penalize you for cannabis use that happened off the job and away from work, or for a drug test that finds only nonpsychoactive cannabis metabolites. The rule has important exceptions, including construction trades, federally required testing, and certain federal-clearance jobs. It also does not protect cannabis use or impairment at work.
Can you be fired for using cannabis in California?
For most covered California workers, Government Code section 12954 has applied since January 1, 2024. As of October 14, 2026, subdivision (a) makes it unlawful for an employer to discriminate in hiring, firing, or employment terms based on your off-duty, off-site cannabis use.
The same subdivision also protects a person from being penalized because an employer-required test found nonpsychoactive cannabis metabolites in hair, blood, urine, or another bodily fluid. In plain words, a metabolite is a leftover chemical your body makes after processing cannabis. It is different from a test designed to identify psychoactive THC.
This is why the result type matters. A positive result is not automatically the same thing as evidence of impairment at work. For a plain-language explanation of that distinction, see THC drug-test cutoffs.
What does AB 2188 and SB 700 protect?
As of October 14, 2026, section 12954(a) protects two related situations:
- Your use of cannabis off the job and away from the workplace.
- An employer-required test that finds only nonpsychoactive cannabis metabolites.
The law also allows an employer to rely on a scientifically valid preemployment screening method that does not screen for nonpsychoactive cannabis metabolites. That is the law’s distinction between a test aimed at psychoactive THC and a metabolite-only result.
There is another practical protection. As of October 14, 2026, section 12954(b) says an employer generally may not ask an applicant about prior cannabis use. Information about prior use found in criminal history is also covered, unless another state or federal law permits the employer to consider or ask about it.
Can California employers still drug test for marijuana?
Yes, testing can still occur in California. The question is whether the role or testing rule falls within an exception, and what the test is designed to detect. A “5-panel” label alone is not enough to answer how an employer will use a result; ask for the employer’s written drug-test policy and which analytes the test covers. This guide to types of THC drug tests explains why urine, hair, blood, and oral-fluid testing answer different questions.
For transportation jobs subject to federal Department of Transportation rules, the federal rule remains especially important. The Department of Transportation says a medical-marijuana recommendation is not a valid medical explanation for a DOT positive, and marijuana remains unacceptable for DOT safety-sensitive employees under those rules.
Which jobs are exceptions?
As of October 14, 2026, California Government Code section 12954 does not apply in every workplace. The main exceptions are below.
| Situation | What the California rule says |
|---|---|
| Building and construction trades | The protection in subdivision (a) does not apply to employees in these trades. |
| Federal testing, funding, licensing, or contracts | The law does not override state or federal laws requiring controlled-substance testing or specifying how testing must be done. |
| Federal background investigation or security clearance | The law does not apply to applicants or employees in positions requiring a federal background investigation or security clearance. |
| Use, possession, or impairment at work | The law does not permit cannabis possession, use, or impairment on the job, and it does not remove an employer’s rights or duties to maintain a drug- and alcohol-free workplace. |
Those exceptions can matter even when cannabis use was legal under California law. A federal requirement tied to the specific job can change the answer, so read the job posting and employer policy closely.
Can an employer see if you went to a dispensary?
Section 12954 is about employment decisions, cannabis-use questions, and drug-test results. It does not create a general answer here about what records a particular business, payment method, or government program may hold. If this affects your job decision, ask the employer which information it uses in hiring and keep the question focused on the written policy.
What if you failed a test, were asked about past use, or want to refuse?
If the issue is a metabolite-only result and you are not in an exception, save the test notice, job posting, written policy, and any messages about the decision. Ask HR for the basis of the action and whether the test distinguished psychoactive THC from nonpsychoactive metabolites. If you are in a union, contact your union representative. An employment lawyer can help assess the facts for your role.
A refusal, a failed result, and a hiring decision can each be handled differently under an employer policy or a federal requirement. Do not assume that refusing is better or worse than testing; ask for the policy before deciding. If a laboratory result is in dispute, this explanation of screening and MRO review can help you understand the usual terms used in the process.
There is no responsible “clean by” timeline to use as a plan for a urine test. Do not use products or methods marketed to alter a sample. Federal workplace-testing rules include specimen-validity procedures, and the practical next step is to address a result through the employer’s stated process.
Before you act
- Read the role description and the employer’s current written drug-test policy.
- Ask whether the position is covered by a federal testing, funding, contract, clearance, or safety requirement.
- Ask what test was used and whether the reported result was psychoactive THC or nonpsychoactive metabolites.
- If you were asked about prior cannabis use during an application, keep a record of the question and response.
This is general information, not legal advice. Employment deadlines can be short, so contact HR, a union representative, or an employment lawyer quickly when a job offer, discipline, or termination is at stake.
