This is reflected in an individual pathologically pursuing reward and/or relief by substance use and other behaviors.<ref>,

Risk Factors

There are several factors that can increase the risk of developing an addiction, including:

• Genetic susceptibility: Genetics account for about half of a person's likelihood to experience addiction. Those with parents or siblings who have struggled with addiction are statistically more likely to develop an addiction.<ref>,

Prevention

Prevention strategies aim to reduce risk factors and increase protective factors. This can be done through:

• School-based prevention programs: These have been proven to reduce the risk of alcohol, tobacco, and other drug use.<ref>,

The prognosis of addiction varies and is largely dependent on the individual's commitment to recovery and adherence to treatment. Some people are able to overcome addiction and lead normal lives, while others may struggle with relapses.<ref>,
