For eleven years, Dr. Michael Segal has been treating PTSD patients – mainly IDF veterans – with medical cannabis. Segal describes the incredible improvements he has seen in his patients: “If you see a post-traumatic patient before and after cannabis, you see two different persons.” Segal compares this type of success in Israel to the lack thereof in the United States in order to emphasize how important it is to prioritize our veterans’ mental health.

Dr. Segal: My name is Michael Segal. I am a psychiatrist. I am head of a department in the psychiatric hospital of Israel, its name is Sha'ar Menashe. I am also belong to the Technion Faculty of Medicine in Haifa, and I have my clinical practice in Haifa, and I treat a lot of patients, actually most of them, with post-trauma.

Seth: Okay.

Dr. Segal: A private practice.

Seth: So, let's dive in on your private practice with PTSD. How long have you associated cannabis with PTSD?

Dr. Segal: 11 years. This time, way before Pesach in 2008, this was my first patient, he convinced me that is something different that I knew.

Seth: He convinced you?

Dr. Segal: With the results of the treatment he received the approval to take cannabis and he changed dramatically from his previous condition that it was one of the worse that I saw.

Seth: Now, things have changed over the past 11 years of course. At the time, how did this all occur? You as the doctor, you as the physician, had to sign off on this, or he ... How did it occur?

Dr. Segal: I treated a lot of patients who were IDF veterans that were injured in the army. They were sent to me by the Ministry of Defense. I began to treat them, actually I treat in the private practice, and I saw that all of them, but moreso all those there that were post-traumatic, improved.

Seth: Improved. From cannabis use.

Dr. Segal: From cannabis use. All of them were treated with combination of treatment, medication that was accepted. Just know [inaudible 00:03:40] like mood stabilizer, like sleep pills, or anti-anxiety, but it was inefficient. Also psychotherapy was inefficient and so on.

Seth: When you say inefficient, how did we actually come to cannabis? I understand you have been convinced since then, but when you say inefficient, what were you seeing that wasn't working? That wasn't-

Dr. Segal: Inefficient? The main inefficiency was related to the traumatic memories, to the flashbacks, to the core symptoms of post-trauma. The depressive state probably was slightly influenced and maybe a little bit sleep, but the core symptoms that they suffered didn't improve with any treatment they received.
