What is a key characteristic of psych addiction related to CNS stimulants?

A key characteristic of psychological addiction related to CNS (central nervous system) stimulants is the craving for the substance despite experiencing negative consequences. This craving is driven by the brain's reward system, which becomes reinforced by the pleasurable effects these stimulants provide, such as increased energy, euphoria, and heightened alertness. Over time, individuals may find themselves prioritizing the use of the substance over other important areas of their life, including relationships, work, and health, leading to detrimental effects. This aspect of addiction highlights the compulsive nature of the behavior, where the individual continues to seek out the drug even when it is clearly harming them, thus illustrating the powerful hold that psychological addiction can have.
