Oral fluid drug testing identifies parent drugs, which has led many employers in California to transition to this method.

Additionally, some employers in California have removed marijuana from their testing panels.

Nonpsychoactive metabolites of THC are not producing a “High” as the drug has been previously ingested and metabolized in the body. California and San Francisco are ok with workers smoking pot on their own time.

Use Caution With Employment Drug Testing In San Francisco

For DOT regulated employees, always follow the DOT regulations which require testing for marijuana.  Additional exceptions to the California law AB 2188 restricting marijuana testing include

  • employees in building and construction trades,
  • positions requiring federal background checks,
  • and individuals under state or federal testing regulations.

Employers in San Francisco might consider eliminating marijuana from their Non-DOT testing panels. Another solution is to run drug testing with oral fluid specimens as opposed to urine and hair specimens.

Strong reasonable suspicion programs, with robust training, can assist employers with making the correct decisions when safety might be compromised. 

Prior to making any adverse employment decisions regarding a marijuana test positive, employers should have an interactive discussion with the employee to determine if the marijuana use may have been off-duty.
