What is heroin?


Heroin (diacetylmorphine) is an illegal, highly addictive semi-synthetic opioid derived from morphine. It is known for its euphoric effects and is commonly abused recreationally. Heroin use can lead to severe health complications, addiction, and overdose.

Historical context

Heroin was first synthesized in 1874 by English chemist C.R. Alder Wright. In the early 20th century, it was marketed by Bayer as a cough suppressant and non-addictive alternative to morphine. However, its addictive potential quickly became apparent, leading to its criminalization in many countries, including the United States in 1924.

How long does heroin stay in your system?

Heroin has a short half-life of about 2 to 6 minutes, as it quickly metabolizes into morphine. However, the morphine produced has a half-life of about 2 to 4 hours. It takes approximately 10 to 24 hours for morphine, which is the primary metabolite of heroin, to be completely eliminated from the body.

Heroin is not available in medical formulations, as it is an illicit substance. It is usually found as a white or brown powder or as a black sticky substance known as "black tar heroin."

Warning: Consuming illicit drugs, including pressed pills, may result in unintended fentanyl exposure, leading to potentially fatal consequences. Exercise caution and consider using fentanyl testing strips to identify the presence of this dangerous substance in street drugs.
