“Marijuana is often used as compassion add-on therapy for treatment-resistant PTSD.

This open-label study evaluates the tolerance and safety of orally absorbable Δ9-tetrahydrocannabinol (THC) for chronic PTSD.

RESULTS:

There were mild adverse effects in three patients, none of which led to treatment discontinuation. The intervention caused a statistically significant improvement in global symptom severity, sleep quality, frequency of nightmares, and PTSD hyperarousal symptoms.

CONCLUSIONS:

Orally absorbable Δ9-THC was safe and well tolerated by patients with chronic PTSD.”
