Substance use disorders (SUDs) 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.
Over time, more and more of the substance is needed to activate the same level of reward, causing the brain’s circuits to become increasingly imbalanced–eroding a person’s self-control and ability to make sound decisions, while producing intense impulses to seek and use the substance.
This is what it means when scientists say that addiction is a brain disease.
The good news – SUDs are preventable and treatable, and brain scans show that once an individual is in recovery, brain tissue can get better.
The animated series aims to expand public understanding about addiction and replace the myths and misinformation that keep substance use disorders (SUDs) from being treated like any other medical condition.
Educational episodes run two-to-three minutes and are meant to be consumed like “snack-packs” of key scientific information.
“ADDICTION” is animated by artist Patrick Smith and produced by the Addiction Policy Forum.
The content of each episode is the result of close collaboration between scientists, patients and families impacted by addiction, and members of our team.
A special thanks to the National Institute on Drug Abuse (NIDA) for the science highlighted in the series.
