What does the genetic model suggest about addiction?

The genetic model of addiction posits that certain individuals may have a genetic predisposition that increases their risk of developing addictive behaviors. This perspective is supported by research indicating that genetics play a significant role in how individuals respond to substances and their likelihood of developing addiction. Various genes can influence neurotransmitter systems, which are critical in the brain's reward pathways, making some people more susceptible to the reinforcing effects of addictive substances.

Furthermore, the model suggests that while genetics can contribute to an increased risk of addiction, they do not act in isolation. The interaction between genetic predispositions and environmental factors—such as family history, social environment, and life experiences—further shapes an individual’s risk for addiction. This understanding emphasizes the complexity of addiction as a multifactorial condition, where genetic, psychological, and social factors intertwine to influence behaviors.

The other perspectives either dismiss the role of genetics entirely or suggest an oversimplified view of addiction as being only environmental, which does not align with the nuanced understanding provided by the genetic model.
