Before you book: if your job involves drug testing, review your employer's policy first — Texas's program doesn't include employment protections. If you qualify, a Texas-licensed physician registered in CURT will enter your low-THC prescription into the registry (no card, no state fee), and you can fill it by delivery or same-day pickup at a satellite location. TCUP is for permanent Texas residents; for patients under 18, a parent or legal guardian should attend.
