Heroin
Heroin was first made in 1898, by the Bayer Company in Germany. At first, it was used as a cough medicine and a painkiller. People thought that heroin would help decrease morphine and opium addiction. But after twelve years, doctors realized that people became strongly addicted to heroin. In 1914, the United States passed the Harrison Act. This was the first of many attempts to control the use of narcotics.
