Abstract
This article reviews the etiology of chemical use and abuse among children and adolescents as well as states the etiological pathways of youth drug behavior between initial, occasional and regular use. The authors also discuss determinants of the onset of chemical use such as the family; peers; early antisocial behavior; school; attitudes, beliefs and personality traits; and early initiation of use. They develop a theoretical premise based on the most current etiological research and offer a social development model that serves as a basis for prevention intervention.
