Neurocognitive risk and protective factors for addiction The area of neurocognitive inquiry into drug abuse is relatively new, but it proceeds from a long history of studying addiction as a cognitive and neurochemical process. We intend to study opiate addiction from the perspective of impulsivity, and hope to find areas of the brain that may be protective for addiction, or conversely create a propensity for addictive behaviour. In this study we have chosen to focus mostly on measures of impulsivity. The reasoning behind this is that many studies have shown that impulsivity can predict drug use and addiction. Evidence abounds for this analysis of the role of impulsivity in addiction. This includes a review of many studies that concludes that "impulsivity is a vulnerability marker for drug addiction" (Verdejo-Garcia Et al, 2008). In addition it has been shown specifically that "heroin and cocaine users show less ability to delay gratification than controls or alcoholics" (Kirby
