Raw opium contains some 20 alkaloid substances, one of which is morphine, in a typical yield of 10%. Morphine was first isolated in 1805 by Friedrich SertÃ¼rner, an apothecary's assistant in Paderborn, Germany, however its basic structure was not correctly determined until 120 years later.
Morphine and heroin are both derived from the opiate poppy. Heroin was first synthesized from morphine back in 1874, and was touted as a safe alternative treatment for morphine addiction. We now know that, once injected, heroin is converted by the body into morphine. So physiologically, they are the same thing.
