Poignant video below from a young veteran of the Iraq War from Wisconsin who speaks calmly and rationally about the horrors of war and the terrible things he witnessed, his resulting post-traumatic stress disorder (PTSD), and how marijuana has helped both him and many of his fellow veterans deal with the stresses of combat. In the video, he urges the passing of state legislation that would allow him and his fellow warriors to be legally treated with medical marijuana for their psychological symptoms.
