Addiction is a complex, chronic condition characterized by compulsive engagement in rewarding stimuli despite adverse consequences. It can manifest through substance use, such as drugs or alcohol, as well as behaviors like gambling, shopping, or internet use. The neurobiological effects of addiction involve changes in brain chemistry and functioning, making it challenging for individuals to control their impulses and seek treatment. The impact of addiction extends beyond the individual, affecting relationships, work, and overall quality of life. Effective treatment often requires a comprehensive approach, including medical intervention, therapy, and support groups, to address both the psychological and physiological aspects of the disorder. Understanding addiction as a treatable condition can help reduce stigma and encourage individuals to seek help for themselves or loved ones.
