Addiction is a complex and severe social problem. Addiction is defined differently by different people, but in the current scientific literature around neuroscience, it is defined as the loss of control over the ability to manage rewarding activities such as eating, gambling, drug use, and sex, to mention a few. This loss of control reflects a transition from goal-directed to habitual behaviors, and scientists argue that as a result of this loss of control, other aspects of the addicted person's life begin to suffer. According to studies, addiction, whether to alcohol, cigarettes, or other substances, is a disease caused in part by our genes, and addiction, like other diseases having a hereditary component such as cancer and heart disease, runs in families (Neurobiology of Addiction, 2015).
