Drug Testing Services for Employers and Employees in Los Angeles, CA

There are many reasons why and scenarios in which employers want to drug test their employees in Los Angeles, CA. These include:

  • Random drug testing: Random drug tests help keep the workplace free of alcohol and drugs.
  • Pre-employment drug testing: The pre-employment drug test is a way to screen applicants before deciding to hire them.
  • Reasonable suspicion drug testing: Reasonable suspicion includes noticing odd changes in an employee's behavior, appearance, or body odor.
  • Post-accident drug testing: If an employee has an accident on the job, it's crucial to rule out (or determine) the involvement of drug and alcohol use.
  • Return-to-duty drug testing: Many employers require negative drug test results before the employee can return to the workplace.

DOT Drug Testing for Companies in Los Angeles, California

DOT drug testing is very strict, especially for individuals in safety-sensitive positions. Combined with the ever-changing laws around drugs and alcohol (and especially cannabis), this can make staying compliant very difficult.

The Types of Drug and Alcohol Testing We Offer at Our Los Angeles Testing Centers

We offer both urine drug test services and hair drug testing in Los Angeles, CA. In addition, we can conduct breath alcohol tests to screen for the presence of EtG (alcohol) in the individual's system.

Urine drug testing is quick and noninvasive, so employers often use it for employee drug testing.

Hair follicle drug testing is harder to cheat because a small hair sample is gathered by a trained and qualified collector. Hair drug testing also has a longer lookback window, making it ideal for identifying longer patterns of drug and alcohol use.

EtG alcohol testing specifically can be done via a hair sample, but breath alcohol tests are quicker and can determine current impairment.

We can provide instant results with POCT drug testing. Negative test results are reported back on the same day.

Drug Testing That Comes to You

If you need us to show up on-site, we offer mobile drug tests in Los Angeles, CA. A collector can meet you (or your employee) within two hours. This is particularly helpful when an employee experiences an accident while on the clock, and the involvement of drugs and alcohol needs to be ruled out.

California Drug Testing FAQs

Do employers in California need to comply with mandatory state-specific rules when drug & alcohol testing?
Yes. California has rules based on court rulings, rather than legislative action.
Is a Drug-Free Workplace policy required in California?
No, however, employers are strongly encouraged to have a written policy in place (Policy is specifically required to comply with the California’s voluntary law). Employers are also strongly encouraged to warn employees and applicants and get signed acknowledgments of the warning, that the use of medication from a foreign source may cause a positive drug test.
What are some compliance requirements in California?
Random testing is limited to safety-sensitive employees only. Employers are encouraged not to let an applicant begin work before the pre-employment drug test result is known.  A reasonable suspicion test unsupported by facts is an unauthorized random test. Requiring a drug test collection during off-duty hours may be prohibited. Employers based in San Francisco are limited in what they can and cannot do, due to a city ordinance.
Are employers in California able to use drug screening for any other claim defenses or state-specific financial benefits?
Yes. Employers may leverage an ‘Intoxication’ defense to a Workers’ Compensation Claim, based on a positive drug test result. A positive drug test may also make an employee ineligible for unemployment compensation. Employers wishing to leverage either of these benefits must voluntarily comply with very detailed program rules.
Does California authorize marijuana (THC) or cannabidiol (CBD) use?
Yes. California permits the personal adult use and the medical use of marijuana for patients that meet specific medical conditions. The laws do not specifically impact employment drug testing programs.
