Hermann Göring, Hitler's closest aide, had served in the Luftstreitkräfte during World War I and suffered a severe hip injury during combat. He became seriously addicted to the morphine that was prescribed to him in order to relieve the pain which resulted from this injury and the gunshot wound, variously described as a thigh or groin injury, that he sustained while taking part in the 1923 Beer Hall Putsch in Munich. In 1925, after consulting his wife, he entered a Swedish mental hospital for detoxification and treatment. When Göring was captured near the end of the war, he was found to be addicted to dihydrocodeine and was subsequently weaned off it.
