The body system most involved in addiction is the nervous system, particularly the brain's reward system. This system releases neurotransmitters like dopamine in response to pleasurable activities, reinforcing behaviors that lead to addiction. Over time, repeated exposure to addictive substances can alter brain chemistry and function, leading to dependence and compulsive behaviors. Other systems, such as the endocrine and immune systems, can also be affected, but the nervous system is central to the addiction process.
