Medical Marijuana for PTSD

Medical Marijuana Therapy Overview

What is medical marijuana?

Medical marijuana has been used to aid in the treatment of post-traumatic stress disorder (PTSD), anxiety and insomnia.  In September 2021, the State of Texas acknowledged and approved the legal use of medical marijuana for PTSD.  It may work even when other medications have failed.

What does medical marijuana treat?

Medical marijuana helps individuals with PTSD, cancer, seizure disorders, spasticity, multiple sclerosis, autism, and amyotrophic lateral sclerosis.

How medical marijuana works

Doctors don’t know exactly how medical marijuana works in PTSD, but they have some ideas. Medical marijuana is thought to affect cannabinoid receptors in the nervous system, and these receptors alter the release of chemicals that are seen with PTSD and anxiety.


Please note you will not be prescribed medical marijuana on your first appointment. Our providers will assess your suitability during your initial evaluation to determine the most suitable treatment plan for your PTSD, which may or may not include a prescription for medical marijuana.

Who is medical marijuana suitable for?

Contraindications are certain heart problems, pregnancy or breastfeeding, or certain prescription medications.  These should be discussed with your provider to evaluate the risks and benefits of medical marijuana for your personal situation.

How is medical marijuana obtained in Texas?

The Texas Compassionate Use Program (CUP) allows certain physicians to prescribe medical marijuana for specific medical conditions.  The patient must be a resident of Texas with one of the above conditions.  Prescriptions are sent to an approved dispensary by a physician registered with the CUP program.

Is medical marijuana safe?

Medical marijuana is safe when done in consultation with specific types of physicians.  The risk of overdose with medical marijuana is very low, and the physician will discuss risks and benefits with your conditions and medications.  It is important to discuss your health history with the physician prior to beginning medical marijuana.
