Substance Abuse or Chemical Dependence
What is substance abuse or dependence?
Substance abuse (alcohol or other drugs)
Substance abuse is a recognized health disorder. It refers to the abuse of illegal or legal substances. Alcohol is the most common legal drug of abuse. Substance abuse causes serious problems at work, school, in relationships, and with the law.

What causes substance abuse or dependence?
The cause of substance abuse and dependence is unclear. It probably involves a mix of genetics, environment, and emotional factors. However, while the first use of drugs or alcohol is voluntary, continued use quickly changes how the brain feels pleasure. Using drugs repeatedly changes the structure of the brain so that a person no longer has control. Substance abuse is a disease that results in the compulsive need for the drug.
