However, it was demonstrated that this was not exclusively a psychological reaction to trauma — there was a biological element as well.

The relationship between addictive behavior and early stressful experiences were observed at the biological level. Childhood trauma can induce a genetic susceptibility to addiction through complex processes instigated by the stressful experience. As a result, the first exposure to drugs can catalyze a genetic alteration which encourages the development of addictive behavior. Teenagers with specific genetic predispositions were especially susceptible to addiction, a finding corroborated by both nonhuman primate and human studies.

The study suggested that, while childhood trauma was a major contributing factor in addiction, it was mediated by healthy experiences later in life. For example, close relationships during adolescence can provide a protective element against addiction, as can participation in team sports.
