California Constitution Privacy Provisions
The privacy protections in California's Constitution and case law impact drug testing. The need to test should be balanced with an individual's right to privacy. Pre-employment and reasonable suspicion drug testing are generally allowed. Random tests are only allowed if an employee is in a safety-sensitive position. There is no definition of safety-sensitive. Considerations include whether the employee is in a position affecting public safety or security, and the degree, severity, and immediacy of harm posed to the employee, other employees, and the public if the employee were to be impaired.
If the employee’s inability to perform his or her job would have an immediate disastrous consequence upon the security or safety of the public, coworkers, or the employee, random testing would likely be permissible. An employee working as a firefighter, policy officer, or security guard is generally considered to be in a safety sensitive position. An employee who works with chemicals or heavy machinery could also be considered to be in a job that is safety sensitive. In Smith v. Fresno Irrigation District, a California court found that a construction-maintenance worker position was safety sensitive because the worker operated power tools and heavy equipment near coworkers and also had to crawl through a half-mile pipe to make repairs. Conditions in the pipe presented a high potential for injury, especially if a drug-impaired employee would become disoriented.
Marijuana testing
As of January 1, 2024, employers may not discriminate against employees based on off-duty use of marijuana. This will impact marijuana testing, although some exceptions apply. In general, employers may not discriminate in hiring, termination, or any term or condition of employment, or otherwise penalize a person, based on a drug test that has found the person to have nonpsychoactive cannabis metabolites in hair, blood, urine, or other bodily fluids. The law does not apply to an employee in the building and construction trades or to applicants or employees hired for positions that require a federal government background investigation or security clearance in accordance with federal regulations. The law does not preempt state or federal laws requiring marijuana testing.
Alcohol and drug rehabilitation
Employers with 25 or more employees must accommodate employees who wish to participate in a substance abuse treatment program, provided the accommodation does not place an undue hardship on the employer. Employees are not entitled to time off with pay for these purposes although the employee may use accrued sick time. Employers must make a reasonable effort to safeguard employees' privacy.
Van and small bus drivers
Under the Public Utilities Code, drivers transporting 15 or fewer passengers are subject to pre-employment, random, and post-accident tests. Employee education and supervisor training is also required under the regulations. Details are outlined in the Public Utilities Code, Sections 1032.1 and 5374(a)(1)(I) and (b).
Unemployment compensation
An individual may be disqualified from receiving unemployment compensation benefits if the individual is discharged for chronic absenteeism due to reporting to work while intoxicated, using intoxicants on the job, or for gross neglect of duty while intoxicated when any of these incidents was caused by an irresistible compulsion to use or consume intoxicants.
Workers’ compensation
Employers are not liable for compensation if an employee's injury is caused by intoxication by alcohol, or the unlawful use of a controlled substance.
Drug-Free Workplace Act
The California Drug-Free Workplace Act of 1990 requires all state contractors and grantees to implement a drug-free workplace policy and establish an employee drug awareness education program. It is similar to the federal law.
San Francisco City Ordinance
A San Francisco city ordinance prohibits random drug testing but allows testing for reasonable suspicion if the employee is in a position to harm someone due to being impaired.

Under the Improve Tracking of Workplace Injuries and Illnesses final rule, the Occupational Safety and Health Administration (OSHA) prohibits employers from using drug testing, or the threat of drug testing, to retaliate against an employee for reporting an injury or illness.
Employers may conduct post-incident drug testing if there is a reasonable possibility that employee drug use could have contributed to the reported injury or illness.
