Testing in California
California generally allows employers to test for cannabis and act on positive results, especially in safety-sensitive roles. A 2021 state law (AB 2188) restricts most pre-employment testing for off-duty cannabis use, but testing remains common and a medical card is not a blanket shield.
California's off-duty lawful-conduct law (Labor Code 96(k)) protects employees from adverse action for lawful off-duty conduct, but courts have held it does not bar drug testing or discipline for cannabis use in many cases.
About Tianeptine
Tianeptine is an atypical antidepressant that acts on opioid receptors at high doses and has been sold as a supplement in some markets. It is not part of standard employment panels.
At high doses it may cross-react on some opioid immunoassays; confirmation by mass spectrometry resolves the result.
Because it is not a standard analyte, a negative routine panel does not rule out use.
False positives & cross-reactivity
- High-dose tianeptine has been reported to interfere with some opioid immunoassays — confirmation resolves it.
