Depression

Depression is one of the most common mental illnesses in the United States. Depression is defined by prolonged feelings of sadness, hopelessness, and despair leading to a loss of interest in activities once enjoyed, a loss of energy, trouble sleeping, and thoughts of death or suicide. It is estimated that around eight percent of the U.S. population suffers from depression. Depression is more common among women with around nine percent of women suffering from depression compared to five percent of men.

Mental illness and substance abuse

Data has shown that those who suffer from mental illness are more likely to suffer from substance abuse than those without mental illness. Around 15 percent of those with some mental illness (excluding serious mental illness) reported substance dependence or abuse, compared to five percent of people with no mental illness. Those with mental illness are more likely to use illicit drugs such as heroin and cocaine, and to abuse prescription drugs than those without mental illness.
