Heroin binds to and activates specific receptors in
the brain called mu-opioid receptors (MORs). Our bodies contain
naturally occurring chemicals called neurotransmitters that bind to
these receptors throughout the brain and body to regulate pain, hormone
release, and feelings of well-being.
The greatest increase in heroin use is seen in young adults aged 18-25.

When MORs are activated in the reward center of the brain, they
stimulate the release of the neurotransmitter dopamine, causing a
sensation of pleasure.

The consequences of activating opioid receptors with externally
administered opioids such as heroin (versus naturally occurring
chemicals within our bodies) depend on a variety of factors: how much is
used, where in the brain or body it binds, how strongly it binds and
for how long, how quickly it gets there, and what happens afterward.
