This has been demonstrated by Kolb,Mychasiuk and Gibb(2013),who have shown that an injury suffered as a result of substance abuse during the neuronal maturation phase has a much poorer potential outcome than if it had been suffered during the synaptogenesis phase of development.Research undertaken by Streissguth,Landesman-Dwyer and Smith(1980)has demonstrated the negative consequences of the introduction of drugs or other substances into the body during periods of rapid neuronal development.Furthermore,Uroslevic,Collins et al.(2015)have proposed that adolescents experience an increased sensitivity of the Behavioral- Activation Approach system(BAS;see also Uroslevic et al.,2012)when presented with substances of abuse.This implies that adolescents with higher sensitivity neurobiological predispositions are at greater risk of substance abuse initiation and excessive alcohol consumption and,in turn,further suggests novel neurobehavioral methods for the identification of those individuals who may be at risk of further substance abuse problems in the future(Uroslevic,2015).Using a hypothesized path model to fit data from the 2011 Youth Risk Behaviour Surveillance System(YRBSS)in their analysis of the relationship between age,gender and bullying(both physical and online),Reed,Nugent&Cooper (2015)suggest that bullying in adolescence may be viewed as a social contagion and a social environmental risk factor that may lead to an increase in anti-social behaviour such as substance abuse.There is no universal definition of bullying.The first psychological definition of bullying was proposed by Olweus(1986,1993)who argued that“a student is being bullied or victimised when he or she is exposed, repeatedly and over time to negative actions on the part of one or more other students”.The repetition of aggression toward another person may be direct,e.g.name-calling or physical violence(see Richardson&Green, 2006),or indirect.Indirect(or relational)aggression,by comparison,is performed wit
