How Is Addiction Hereditary?

Addiction can have a genetic component, meaning that it can run in families. Research has shown that certain genes can make a person more susceptible to addiction, and individuals with a family history of addiction may have a higher risk of developing an addiction themselves. However, genetics is not the only factor in addiction, and environmental factors such as upbringing, exposure to drugs or alcohol, and social and cultural influences also play a role. Therefore, having a genetic predisposition to addiction does not necessarily mean that a person will develop an addiction.
