A person can be legally eligible for the Texas program even when researchers do not yet know whether cannabis improves the consequences of that diagnosis. Traumatic brain injury is the clearest example of why eligibility and efficacy must be discussed separately.
Texas includes traumatic brain injury
Texas DPS lists traumatic brain injury among the qualifying conditions for permanent Texas residents. A registered physician must determine that the potential benefit of low-THC cannabis is reasonable in light of the risk.1
The diagnosis may involve very different realities, from persistent headaches after a concussion to severe physical, cognitive, and behavioral disability. A generic “TBI” label does not tell a clinician which symptom is being targeted or which risks are most important.
The research gap is substantial
A clinical review focused on TBI found sparse evidence and emphasized that patients often know little about proven benefits and the range of possible effects.2 Research about cannabis exposure at the time of injury also does not answer whether cannabinoids safely improve chronic post-injury symptoms.3
Claims about neuroprotection often come from laboratory or animal research. They should not be translated into a promise that cannabis repairs an injured human brain.
TBI can affect memory, attention, reaction time, mood, balance, and judgment. THC can affect some of the same functions, so a patient and clinician need a baseline and a way to recognize worsening.
Choose a measurable target and protect function
If a clinician considers a cannabinoid trial, the plan should focus on one symptom and protect rehabilitation goals. For example, a sleep target should not come at the cost of worse daytime balance or attention. A headache target should not obscure a new neurological warning sign.
- Review seizure history, psychiatric symptoms, falls, and substance-use history.
- Ask how the product could affect therapy participation, driving, school, or work.
- Include a caregiver when the injury affects memory or decision-making.
- Know which new symptoms require urgent neurological care rather than dose adjustment.
Getting a Texas prescription
If the registered physician approves, the prescription is entered in CURT. Texas does not mail a card, and patients do not self-register with DPS. The licensed dispensary verifies the prescription through the registry.4
The state physician search provides a noncommercial route to participating clinicians. Our Texas conditions guide covers the other approved categories.

Frequently Asked Questions
Does traumatic brain injury qualify in Texas?
Yes. TBI is a named qualifying condition, subject to Texas residency and a registered physician’s risk-benefit determination.
Does cannabis repair a traumatic brain injury?
No clinical evidence establishes cannabis as a treatment that repairs an injured human brain.
Why is extra caution important after TBI?
TBI and THC can both affect attention, memory, reaction time, balance, mood, and judgment, making individualized monitoring important.
