Quizplus · Accepted Answer

Dysregulation in the dopamine pathway is a major factor underlying drug cravings and addiction. Dopamine is a neurotransmitter that is involved in the brain’s reward system and plays a key role in motivating behaviors related to obtaining rewards. Drugs of abuse, such as cocaine and amphetamines, increase dopamine release in the brain, which is thought to be a key component of their addictive properties. Chronic drug use can lead to dysregulation of the dopamine system, resulting in decreased sensitivity to natural rewards and increased dependence on drugs to stimulate dopamine release.
