Substance Abuse

Substance abuse is a pattern of compulsive substance use marked by recurrent significant social, occupational, legal, or interpersonal adverse consequences, such as repeated absences from work or school, arrests, and marital difficulties.
Addiction is a state of psychological or physical dependence (or both) on the use of alcohol or other drugs. The term is often used as an equivalent term for substance dependence and is sometimes applied to behavioral disorders, such as sexual, internet, and gambling addictions. Cravings for substances and substance abuse may be treated with medications, therapy, or both.
