In the real world there is no nature vs. nurture argument, only an infinitely complex and moment-by-moment interaction between genetic and environmental effects

The hardcore drug addicts that I treat, are, without exception, people who have had extraordinarily difficult lives. The commonality is childhood abuse. These people all enter life under extremely adverse circumstances. Not only did they not get what they need for healthy development; they actually got negative circumstances of neglect. I don’t have a single female patient in the Downtown Eastside of Vancouver who wasn’t sexually abused, for example, as were many of the men, or abused, neglected and abandoned serially, over and over again. That’s what sets up the brain biology of addiction. In other words, the addiction is related both psychologically, in terms of emotional pain relief, and neurobiological development to early adversity.

For a person with ADD, tuning out is an automatic brain activity that originated during the period of rapid brain development in infancy when there was emotional hurt combined with helplessness. At one time or another, every infant or young child feels frustration and psychological pain. Episodic experiences of a distressing nature do not induce dissociation, but chronic distress does — the distress of the sensitive infant with unsatisfied attunement needs, for example. The infant has to dissociate chronic emotional pain from consciousness for two reasons. First, it is too overwhelming for his fragile nervous system. He simply cannot exist in what we might call a state of chronic negative arousal, with adrenaline and other stress hormones pumping through his veins all the time. It is physiologically too toxic. He has to block it out. Second, if the parent’s anxiety is the source of the infant’s distress, the infant unconsciously senses that fully expressing his own emotional turmoil will only heighten that anxiety. His distress would then be aggravated — a vicious cycle he can escape by tuning out.
