- Genetics: There is a strong genetic component to substance use disorders. Studies have shown that people who have a family history of substance use disorders are more likely to develop these disorders themselves.

When people use substances, they release dopamine, a neurotransmitter that is associated with pleasure. Over time, the brain can become dependent on these substances to produce dopamine, leading to addiction.
