Opiate addiction causes lowered levels of what neurotransmitter?

Explanation:
Opiates hijack the brain’s natural opioid system, which relies on endorphins as the body’s own opioids. When opioids bind to mu receptors, they produce strong reward and analgesic effects, and over time the brain compensates by reducing its own endorphin production and/or receptor sensitivity. This downregulation leads to lower baseline endorphin activity when not using, contributing to withdrawal discomfort and a drive to continue using to restore that endorphin tone. While dopamine and other systems are involved in the overall addiction process, the neurotransmitter most directly linked to the opiate system and its withdrawal is endorphins.
