Heroin was discovered at St Mary's Hospital, London, in 1874(1). It was discovered by C.R. Alder Wright(2).
At first researchers felt that Heroin (Diamorphine) didn't have any significant advantage over Morphine. It wasn't used as a medicine until a German company Bayer, marketed it as heroin in 1898(3).
It was named Heroin after the German word for "heroic"(4). It was marketed as a new cough medicine(5).
Heroins non use quickly changed after that. The American Medical Association in 1906 recommended Heroin for bronchitis, pneumonia, whooping cough, laryngitis, and hay fever. Other early literature said Heroin was also good for angina pectoris, heart failure, aortic aneurysm, dysphagia, cancerous stomach, influenza, multiple sclerosis, gynecological diseases, inducing labor and narcosis, high blood pressure, diabetes, hiccups, depression, and psychosis (6 ).
