Before you book: active-duty service members can't participate under military law, and TCUP requires permanent Texas residency. Veterans: bring your records, including any PTSD documentation. 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'll fill it through a licensed dispensing organization with your government photo ID. For patients under 18, a parent or legal guardian should attend.
