Heroin, an opiate, raises the level of dopamine in the brain, and dopamine is one of four chemicals responsible for happiness.

Over half a million Americans tried heroin in 2013 — a 150 percent increase in about six years.

In 2013, more than 8,000 people in the U.S. died from heroin overdoses.

Cocaine, street methadone, barbiturates and alcohol rank high with causing dependence, right after heroin.
