[Origins of addictive behavior: evidence from a study of stressful chilhood experiences].

A population-based analysis of over 17,000 middle-class American adults undergoing comprehensive, biopsychosocial medical evaluation indicates that three common categories of addiction are strongly related in a proportionate manner to several specific categories of adverse experiences during childhood. This, coupled with related information, suggests that the basic cause of addiction is predominantly experience-dependent during childhood and not substance-dependent. This challenge to the usual concept of the cause of addictions has significant implications for medical practice and for treatment programs.
