The book highlights how inherited predispositions can significantly impact addiction, emphasizing that it's not simply a matter of willpower but a complex disease influenced by genetics. Notably, research indicates that genetic variations can alter neurobiological pathways related to reward and impulse control, making some individuals more susceptible to addiction.
The book progresses from basic genetics to specific genes implicated in addiction, drawing from twin studies and genome-wide association studies. It examines gene-environment interactions, acknowledging that factors like childhood experiences and social environment can either exacerbate or mitigate genetic risks.
Furthermore, it delves into the ethical and social implications of genetic research on addiction, such as concerns about genetic discrimination and privacy. By translating complex scientific findings into accessible language, ""Genetics and Addiction"" bridges biology, psychology, and life sciences, offering valuable insights for students, healthcare professionals, and anyone interested in understanding the genetic landscape of addiction.
