Heroin overdoses in the United States rose sharply from 2006 to 2015, but since 2016 the number of deaths has trended down. There were 9,173 heroin-related deaths reported in 2021. In the United States, heroin is sold illegally, so there is no control over the quality or strength of the drug. Also, it is sometimes mixed with other poisonous or dangerous substances, such as fentanyl.

Most people who died from an overdose in the United States from 1999 to 2019 were aged 35 to 54. Many people who use heroin also abuse prescription pain medicines and other drugs. They may also abuse alcohol. These combinations of substances can be very dangerous.
