Is medical marijuana legal in Texas?
A narrow version is. The Texas Compassionate Use Program allows registered physicians to prescribe low-THC cannabis, defined in Tex. Occ. Code §169.001 as products with no more than 10 milligrams of THC per dose, for a list of conditions that since 2025 includes chronic pain, traumatic brain injury, Crohn's disease and terminal illness. Smoking is excluded, home growing is not allowed, and everything outside the program is still charged under the ordinary drug laws.
- Texas has prescription low-THC cannabis, not a general medical marijuana program.
- The 2025 expansion added chronic pain, TBI, Crohn's and other inflammatory bowel disease, and terminal or hospice patients.
- The cap is 10 milligrams of THC per dosage unit, prescribed as a 90 day supply with up to four refills.
- An out-of-state medical card protects nothing in Texas.
- Ordinary possession is still a crime, from a Class B misdemeanor at 2 ounces of flower to felonies for any THC concentrate.
The gap between what people believe about medical marijuana in Texas and what the statute says is where criminal cases come from. This page states the current rules, as written, after the Legislature's 2025 expansion. Peter M. Barrett has defended drug cases in Dallas County since 1994, with more than 150 jury trials. See our Dallas drug crime defense page.
What the Compassionate Use Program actually is
Under Occ. Code §169.003, a physician registered with the state may prescribe low-THC cannabis to a permanent Texas resident diagnosed with one of the listed conditions, where the physician certifies the benefit outweighs the risk. A prescription covers a 90 day supply and may include up to four refills. The products come only from state-licensed dispensing organisations, and "medical use" is defined to exclude smoking, though vaporised administration is not smoking under the statute's own definition.
Who qualifies now
| Qualifying conditions, §169.003(a) | Since |
|---|---|
| Epilepsy and seizure disorders | The original 2015 program |
| Multiple sclerosis and spasticity | Early expansions |
| ALS, autism, cancer, incurable neurodegenerative disease, PTSD | 2019 to 2021 expansions |
| A condition that causes chronic pain | The 2025 expansion |
| Traumatic brain injury | The 2025 expansion |
| Crohn's disease or other inflammatory bowel disease | The 2025 expansion |
| Terminal illness, or hospice and palliative care | The 2025 expansion |
| Conditions in an approved state research program | Statutory route for additions |
The chronic pain addition is the big one: it moves the program from rare diseases toward the population most other states serve. If you have wondered whether you qualify now, the honest answer is that far more Texans do than in any earlier year of the program.
What a prescription protects, and what it does not
| Situation | Protected? |
|---|---|
| Low-THC product from a Texas licensed dispensary, valid prescription | Yes, lawful under the program |
| Flower bought anywhere, with any medical explanation | No. Possession is charged under §481.121 |
| Out-of-state medical card, product from Oklahoma or Colorado | No. The card has no effect in Texas |
| THC vape pens, edibles, dabs outside the program | No, and concentrates are felonies at any amount |
| Hemp-derived products at or under 0.3 percent delta-9 THC | Legal to sell, but lab results decide, not labels |
The possession ladder for ordinary marijuana runs from a Class B misdemeanor at two ounces or less, through a Class A to four ounces, a state jail felony to five pounds, and on up (Health & Safety Code §481.121). Concentrates sit outside that ladder entirely and grade far worse, which is covered in the penalty groups guide. The wider landscape, hemp, delta-8 and the rest, is in is weed legal in Texas.
If you are charged anyway
- The stop and the search decide most possession cases before the substance does: see motions to suppress.
- The lab report is the case. Since hemp legalisation, the State must prove the THC concentration, and testing backlogs and methods are contestable.
- A medical story is mitigation, not immunity. A genuine condition and treatment history shape charging decisions and outcomes even where the program's protection does not apply.
- Watch the paraphernalia and DWI edges. A lawful prescription does not authorise driving while intoxicated, and THC DWI cases are their own fight.
Common questions
Can I get medical marijuana for chronic pain in Texas?
Yes, since the 2025 expansion. A condition that causes chronic pain is now on the qualifying list in Occupations Code section 169.003, prescribed by a registered physician as low-THC cannabis, capped at 10 milligrams of THC per dose.
How strong is Texas medical cannabis?
The statute defines low-THC cannabis by dose: no more than 10 milligrams of tetrahydrocannabinols per dosage unit. That is a per-dose cap rather than the old percentage-by-weight rule, and prescriptions issue as a 90 day supply with up to four refills.
Can I smoke medical marijuana in Texas?
No. Medical use is defined to exclude smoking. The definition does allow administration by vaporised or aerosolised inhalation, which the statute expressly says is not smoking.
Does my out-of-state medical marijuana card work in Texas?
No. Texas law gives no effect to other states' cards or products. Marijuana purchased legally in Oklahoma, New Mexico or Colorado becomes contraband at the Texas line, and prosecutions from exactly that fact pattern are routine on the highways into Dallas.
Is possession still a crime if I clearly use it medically?
Outside the program, yes. Two ounces or less of flower is a Class B misdemeanor, and concentrates are felonies at any amount. A documented medical condition matters at the negotiation and punishment stages, but it is not a defense to the charge itself.
