Medical and governmental authorities have defined abuse as the non-medical use of a substance. According to American Psychiatric Association 2000, abuse of a drug is referred to as a maladaptive pattern of repeated use that brings on significant adverse consequences, including the failure to fulfill obligations, repeated use in physically hazardous situations, as well as recurrent social, interpersonal, and legal problems. • There is a difference between abuse and dependence. When someone abuses a drug, that means they are using it without medical or legal consent. Dependence involves compulsive use. When someone is dependent on a drug, that means they actually crave the drug or that they literally need it.
