From 1898 through to 1910, heroin was marketed as a cough suppressant by trusted companies like Bayer -- alongside the company's other new product, Aspirin.From wikipedia:In 1895, the German drug company Bayer marketed diacetylmorphine as an over-the-counter drug under the trademark name Heroin. The name was derived from the Greek word "Heros" because of its perceived "heroic" effects upon a user. It was developed chiefly as amorphine substitute for cough suppressants that did not have morphine's addictive side-effects. Morphine at the time was a popular recreational drug, and Bayer wished to find a similar but non-addictive substitute to market. However, contrary to Bayer's advertising as a "non-addictive morphine substitute," heroin would soon have one of the highest rates of dependence among its users.
