The Hijacker - Addiction Series (Episode 1)

(3:17 minutes)

Substance use disorders (SUDs), what some refer to as addiction, affect tissue function in two main parts of the brain: the limbic system (responsible for basic survival instincts) and the prefrontal cortex (where decision-making and impulse control live).

Substance use activates the dopamine process in the survival center much more powerfully than natural rewards like food or sex. When repeated it can hijack the brain, making it think that the substance is the most important thing for survival.

The good news – SUDs are preventable and treatable, and brain scans show that once an individual is in recovery, brain tissue can get better.
