Drug of abuse is illegal drugs or prescription drugs (such as oxycodone or valium) for non-medical purposes. The non-medical purposes of prescription drugs include taking drugs for longer than prescribed by doctors, or using them for purposes other than prescribed by doctors. If the drug is taken according to the doctor's instructions, it is not drug abuse.
