Various theories suggest that human beings differ regarding their susceptibility to environmental stimuli, some of these theories have their origin in the field of developmental psychology. From an evolutionary perspective, it has been assumed that this susceptibility trait follows a normal distribution in the population, with a minority being…

Using alcohol, cigarettes, and marijuana during adolescence is associated with risks, yet there is no single cause for adolescent substance use. The etiology of substance use develops over time, across multiple levels of influence. Informed by developmental perspectives, in this review, we provide an overview of biological (e.g., genetic,…
