What's drug abuse, misuse of drugs, drug addiction
1, Definition of drug abuse
Drug abuse is the use of illicit drugs, or the abuse of prescription or over-the-counter drugs. The abuse of legitimate drugs can be done by using the drugs in a manner or in quantities other than directed, or for purposes other than legitimate purposes.
Drug abuse has a wide range of definitions related to taking a psychoactive drug or performance enhancing drug for a non-therapeutic or non-medical effect. All of these definitions imply a negative judgement of the drug use in question. Some of the drugs most often associated with this term include alcohol, amphetamines, barbiturates, benzodiazepines, cocaine, methaqualone, and opium alkaloids. Use of these drugs may lead to criminal penalty in addition to possible physical, social, and psychological harm, both strongly depending on local jurisdiction. Other definitions of drug abuse fall into four main categories: public health definitions, mass communication and vernacular usage, medical definitions, and political and criminal justice definitions.
