Research in human behavior rarely lends itself to the scientific rigors which allow for definitive cause and effect answers even if they exist. Perhaps no facet of human life has a simple origin, and certainly that is true of behavior which involves all levels of personality function and social interaction such as occurs in drug abuse. Drug abuse undoubtedly is overdetermined behavior with multiple etiological factors in a constantly fluxuating interaction. Most observers agree that drug abuse by the youth has become a major problem, but differences arise when the sociological and psychological factors of etiology are discussed. The many concepts of etiology are more or less products of the individual observer\u27s orientation and past experience, and therefore, they rarely are subject to cross validation
