I was in the Marine Corps for 11 years and did two combat tours before being medically discharged. After coming back home, I was put on 40 different medications over the course of five years. In 2012, after watching a documentary, I decided to try cannabis. I felt more relaxed after one joint than I had after tons of combinations of pharmaceuticals. I threw away my pills and my quality of life is better than it has been in years.
I think it is very important to note that cannabis is not a cure for PTSD, but in combination with therapy, it can open a whole new world for you.
