Can I be fired for using medical marijuana? - Texas

In Texas, medical marijuana patients do not have employment protections under state law. Even if you are legally registered in the Compassionate Use Program and using low‑THC cannabis as prescribed, employers can still enforce their own drug‑free workplace policies. That means you may be disciplined or terminated if you test positive for THC, regardless of your patient status. Texas law does not require employers to accommodate medical marijuana use, and cannabis remains illegal at the federal level, which further influences workplace rules.
