Oerter retired from athletics after the 1968 Olympics. He later eyed a comeback and took anabolic steroids in 1976 under medical supervision in order to put on muscle mass. However, he stopped the course as this affected his blood pressure and failed to give much improvement on the field. After this he advised athletes to avoid such drugs and focus on training and technique instead. He was critical of the increase of drug use and the subsequent testing in track and field, stating that it had destroyed the culture of athlete camaraderie and that the banning of athletes such as Ben Plucknett was merely scapegoating by international officials.
