Heroin is a semi-synthetic opioid substance of the morphinan class. It is a derivative of morphine, a natural product of the opium poppy (Papaver somniferum). Heroin is known for its highly addictive properties and it makes up a large portion of the illicit traffic in narcotics. Fatal overdose may occur when opiates are combined with other depressants, such as benzodiazepines, barbiturates, gabapentinoids, thienodiazepines, alcohol or other GABAergic substances.

Subjective effects include sedation, leading to “nodding off” and microsleeps, along with intense physical euphoria, pain relief, and respiratory depression that can be fatal. It also causes appetite suppression, dehydration, constipation, cough suppression, decreased libido, and cognitive euphoria characterized by emotional bliss and anxiety suppression. High doses can result in double vision, internal hallucinations, and nausea severe enough to cause vomiting.

Heroin was first synthesized from morphine by British chemist C.R. Alder Wright in 1874, and was introduced as a commercial product by the Bayer Company of Germany in 1898. Although the name “Heroin” is a trade name, it has since been widely adopted for many other recreational depressants that may or may not contain pure diacetylmorphine.
