Alcohol and Drug Testing Laws in California: What Employees Should Know

Drug Testing Laws

If you’re working in California and feeling unsure about your rights when it comes to alcohol and drug testing, you’re not alone. Between new laws, shifting workplace norms, and the growing legalization of medical marijuana and recreational marijuana, it’s easy to feel overwhelmed. Let’s walk through what you need to know—whether you’re about to start a job, returning from treatment, or just trying to protect your privacy.

Can Employers Drug Test in California

Can Employers Drug Test in California?

Yes, but there are limits. California has some of the most employee-friendly drug testing laws in the country. While pre-employment drug testing is allowed, it can only be done after a conditional job offer has been made. So, if you’re a job applicant, your prospective employer can request a urine sample or other pre-employment drug screening, but only after they’ve offered you the job.

That said, California drug testing laws have changed, especially when it comes to cannabis. Thanks to a new law—AB 2188—employers are no longer allowed to discriminate based on nonpsychoactive cannabis metabolites, which means you can’t be penalized for marijuana use that happened days or weeks ago. Employers must focus on current impairment, not past use.

What About Random Drug Testing or Alcohol Testing at Work?

Generally speaking, random drug testing isn’t allowed in California unless you’re in a safety-sensitive job, like operating heavy machinery or working in public safety. Even then, your employer must have a valid reason to conduct drug tests.

As for alcohol testing or drug tests after a workplace accident, those are typically allowed if there’s reasonable suspicion—like if you’re visibly impaired or there’s been an incident on the job. Again, the goal here is employee safety, not punishment.

Can Employers Maintain a Drug-Free Workplace?

Yes—California employers still have the right to enforce a drug-free workplace policy, especially when it comes to illegal drugs, drug abuse, or being impaired on the job. So even if you use medical marijuana legally in your off hours, your boss can still take action if you show up to work high.

And while employers may test employees under specific conditions, they still have to follow all the federal law, state law, and local laws that protect your rights.

What Should You Do If You’re Concerned?

Can employers drug test employees? Yes.

If you’re currently navigating legal matters related to employment drug testing—or worried about a positive drug test—you don’t have to go it alone. It’s smart to consult legal counsel, especially if you think you’re being treated unfairly or your employer is not following California’s strict testing laws.

Also, keep in mind that the hiring process often includes some type of pre-employment testing, but once you’re on the job, your employer needs a clear reason to test you—like reasonable suspicion or post-accident drug testing.
