Heroin

Heroin

Heroin is a powerful and highly addictive opioid drug synthesized from morphine, a natural substance extracted from the seed pods of certain varieties of poppy plants.

It typically appears as a white or brown powder, but it can also be found as a sticky black substance known as “black tar heroin.“

It can be injected, snorted, or smoked.

The chemical composition is diacetylmorphine, with the molecular formula C21H23NO5.

This chemical structure allows it to rapidly cross the blood-brain barrier, where it is converted back into morphine.

In the brain, morphine binds to opioid receptors, leading to the suppression of pain and the release of dopamine, a neurotransmitter associated with pleasure and reward.

This combination of effects produces intense feelings of euphoria and relaxation.
