Post-traumatic stress disorder or PTSD is the overall term for several anxiety related reactions that occur after the patient is exposed to an event that causedPTSDpsychological trauma. The condition is especially common among military personnel who have recently gone through active duty, and even people who experience accidents or violent attacks. Most such patients become fixated on the original event, and have no control over reliving it over and over.

Post-traumatic stress disorder is a complex condition that requires extensive medical evaluation and treatment. If the doctor approves it however, medical marijuana may be used to reduce stress and anxiety among PTSD patients.
