Drug Testing Services We Offer in San Francisco, CA

San Francisco is a major port and the foremost tech industry hub in the United States. The city’s bustling tourism industry attracts more than 25 million annual visitors.

Despite San Francisco’s economic success, the city has struggled to curb illegal drug use. The early 2020s saw an increase in public drug consumption, which has unfairly impacted the area’s reputation.

To help employers and individuals, we offer a robust variety of drug testing services in San Francisco. Some of our most popular services in the area include:

Workplace Drug Testing Programs

In the tech industries, workplace drug use hampers innovation and lowers product quality. In the tourism industry, drug-using workers leave negative impressions on visitors, reducing the likelihood of return visits. And these impacts pale in comparison to the safety concerns stemming from drug use in manufacturing and transportation companies.

Our workplace drug testing services can identify employees who use drugs and enable you to craft effective prevention and training programs.

Caution is advised for non-regulated employers in San Francisco where random drug testing is restricted. This does not affect DOT required random testing.

Marijuana Testing For Employers in San Francisco, CA

Employment drug testing for marijuana in San Francisco and throughout California is now restricted due to the implementation of AB 2188, which took effect on January 1, 2024. This legislation reflects a growing trend in California aimed at safeguarding employees who consume legal marijuana during their off-duty hours. Furthermore, traditional workplace drug testing methods have been criticized for their inability to accurately assess impairment in the workplace. As a result, urine testing for marijuana has been limited, while oral fluid testing has been recommended. This method is capable of detecting the active component of marijuana, making it a viable option for employers, particularly in cases of reasonable suspicion or post-accident scenarios. Oral fluid drug testing provides insights into recent drug use and does not measure THC, a non-psychoactive metabolite of cannabis.

DOT-Compliant Testing

If you work in the transportation industry, you must drug test your employees regularly using Department of Transportation (DOT) approved tests.

Marijuana is prohibited in the DOT program and always part of the DOT drug testing panel. Lean more about DOT compliant drug testing services from National Drug Screening.

Common Drug Test Panels in San Francisco, CA

To detect drug abuse, companies in San Francisco need to employ a variety of drug tests and screening methods. Some of the most common drug panels we provide in San Francisco, CA, include:

10-Panel Drug Test

The 10-panel drug test screens for 10 commonly used illicit and prescription drugs, including but not limited to:

  • THC
  • Opiates
  • Benzodiazepines
  • Barbiturates
  • Amphetamines


For non-regulated companies using urine drug testing, marijuana should be eliminated from the drug testing panel. In order to included marijuana, switch over to oral fluid drug testing.

Urine Sample Drug Testing

The urine sample-based drug test is the most commonly used specimen collection method. This test generates highly accurate results quickly and is great at pinpointing recent drug use. However, it is unsuitable for detecting long-past drug use, as most drug compounds only remain in urine for about five days.

Oral Fluid or Saliva Drug Testing

For the detection of recent drug use, oral fluid testing is the preferred method. This straightforward collection process is usually conducted on-site by a representative of the employer. Oral fluid testing can be conducted either in a laboratory setting or through instant testing products. Additionally, for employees located in remote areas or those working from home, a remote proctored oral fluid testing option is accessible. In California, oral fluid testing is an excellent choice for those non-regulated companies wanting to continue testing for marijuana.

Hair Drug Testing

Companies with zero-tolerance drug policies often turn to hair-sample tests. Human hair retains drug compounds for months, making this test type ideal for identifying drug use that happened a while ago. Hair can be taken from the head, face, arms, legs or underarms for reliable hair drug testing.
