Medical Marijuana

Although several states across the country have legalized medical marijuana, Texas has no such regime. Anyone traveling to Texas carrying marijuana can be arrested and charged with possession or other offenses, regardless of whether they have a valid prescription. Medical marijuana is charged as either possession or possession with intent to distribute depending on the amount involved.

The cultivation of marijuana plants is also treated as possession or possession with the intent to distribute based on the total weight of the plants.

Medical Marijuana Prescriptions

Patients can obtain prescribed Low-THC cannabis when:  

  • They are permanent residents of Texas  
  • They have one of the medical conditions listed above 
  • A CUP registered physician prescribes the cannabis
  • The same qualified physician decides the benefits outweighs the risks

There is no age limit for prescriptions. Patients under 18, however, require the approval of a legal guardian.  

Getting a prescription can involve:  

  • A physician entering a prescription in the Compassionate Use Registry of Texas (CURT)
  • The patient or legal guardian going afterward to any licensed dispensary to get the prescription
  • The patient or legal guardian providing ID and patient’s, last name, date of birth, and last five digits of their Social Security Number

A physician’s qualifications to prescribe low-THC are outlined under Section A169.002 of Senate Bill 339. A physician is qualified to prescribe low-THC cannabis to a patient with intractable epilepsy when the physician:

  • is licensed in accordance with state law
  • dedicates a significant portion of clinical practice to the evaluation and treatment of epilepsy
  • is certified by the American Board of Psychiatry and Neurology in epilepsy, or neurology or neurology with special qualification in child neurology and is otherwise qualified for the examination for certification in epilepsy, or in neurophysiology by the American Board of Psychiatry and Neurology or the American Board of Clinical Neurophysiology

A physician described by Section A169.002 can prescribe low-THC cannabis to alleviate a patient ’s seizures if:

  • the patient is a permanent resident of Texas
  • the physician complies with the registration requirements of Section 169.004
  • the physician certifies to the department that:
    • the patient is diagnosed with intractable epilepsy;
    • the physician determines the risk of the medical use of low-THC cannabis by the patient is reasonable in light of the potential benefit for the patient; and
    • a second physician qualified to prescribe low-THC cannabis under Section 169.002 has concurred with the determination under Paragraph (B), and the second physician’s concurrence is recorded in the patient’s medical record

Medical Marijuana Defenses

Activists in Texas are working to advance a bill that would make marijuana use for medical purposes as advised by a doctor to be an affirmative defense for certain amounts of marijuana possession. An affirmative defense, if proven, would require the charges against you to be dismissed.

Currently, though, juries do not take into account why you were in possession of marijuana when deciding the case, just that you knowingly had possession.

Until a law passes to allow medical marijuana, the best defense is a lawyer experienced in the methods of investigation, search, and seizure. If law enforcement oversteps their bounds, evidence can be excluded from the trial which can cause their case to be unwinnable.

There are several likelihoods for marijuana possession charges including community service, a diversionary program, suspension of your driver’s license, probation, or jail time. The conviction may be dismissed from your record if you are able to successfully complete a deferred sentence.

Tarrant County Resources for Medical Marijuana

Texas Medical Marijuana ― This state website provides an overview of Texas medical marijuana laws including definitions, an explanation of CURT, and a marijuana law guide. You can also find information about the CUP that includes an overview, laws and regulations, and licensing and registration. When searching for registered physicians in CURT, you can visit the official CURT website provided by the Texas Department of Public Safety and should provide a search tool or database where you can find registered physicians authorized to prescribe low-THC cannabis.

Texas cancer patients and people with PTSD will soon be able to join state’s expanded medical marijuana program ― View an August 11, 2021 article from the Texas Tribune reporting that the Texas Compassionate Use Program planned to expand to include people with PTSD and cancer of all stages, allowing them to use “low-THC cannabis.” The state’s cannabis program was serving less than 6,000 people as of May, and the new law expanded to include veterans with PTSD and an estimated 114,000 Texans who have cancer, according to the Texas Department of State Health Services. The new Texas law not only expanded the state’s cannabis program but also doubled the percent of THC allowed in products to 1 percent.
