In 2012, a European research study addressed trauma suffered by persons who witnessed legal assisted suicide in Switzerland.[1] The study found that one out of five family members or friends present at an assisted suicide was traumatized. These people,
experienced full or sub-threshold PTSD (Post Traumatic Stress Disorder) related to the loss of a close person through assisted suicide.[2]* * *
