There is evidence that addiction can have a genetic component, meaning that a person may have an increased risk of developing an addiction if they have a family history of addiction. Studies suggest that genetic factors may be responsible for 40-60% of a person’s susceptibility to addiction. However, genetics is not the only factor that contributes to addiction. Environmental factors, such as exposure to drugs or alcohol and stressful life events, can also play a significant role in the development of addiction. It is important to note that having a family history of addiction does not necessarily mean that a person will become addicted, but it may increase their risk.
