Heroin was first used in as a cough suppressant and a non-addictive substitute
for morphine in 1898. Then an addictive potential was reconized and was
prohibited in the U.S. Heroin produces a "rush" or "high" immediately after
it is taken. It also increases energy. Heroin is usually taken into
the bloodstream by a needle. In the 70's heroin needles were
often shared, causing HIV or AIDS.
