How to understand addiction
Recognize that addiction is a disease, not a choice.
People used to consider addiction a sign of weakness, a lack of willpower, or poor morality. However, today addiction is considered a disease because of the way it affects the brain.
Approaching addiction in this way can make it easier for you to help an addict. People who become addicted to substances and/or behaviors require treatment to stop engaging in the addictive behavior, but the treatment is not always medical.
