And Addiction Drug abuse is use of drugs or alcohol that cause consequences in the abuser s life.
Consequences can be physical, mental, family, relationship, work, legal, or financial in nature.
Many people also abuse nicotine, caffeine, and alcohol. Body builders may abuse anabolic steroids. Drug abuse can progress to addiction in susceptible individuals. When this occurs, drug use becomes the person s primary focus over his or her other life responsibilities, including health, work, and family. Some drugs also produce physical dependence and severe withdrawal, when use is stopped without medical supervision.
