During what phase do behavioral indicators such as decreased activities and poor performance become evident?

The Dependency/Addiction Phase is characterized by significant changes in an individual's behavior as the substance use escalates and becomes a central focus of their life. During this phase, numerous behavioral indicators emerge, including decreased participation in everyday activities, declining performance at work or school, and a general neglect of responsibilities. These changes are often symptoms of the addiction itself, as the individual may prioritize obtaining and using the substance over other aspects of their life.

In contrast, the other phases highlight different aspects of substance use. The Regular Use Phase may not show such pronounced indicators, as individuals might still function relatively normally, despite the onset of habitual use. The Acute Phase refers to an immediate period of substance use, where effects are often temporary and intense, while the Withdrawal Phase focuses on symptoms that arise when a person stops using a substance. During withdrawal, behaviors indicating poor performance may occur, but they stem from the physiological impact of discontinuation rather than the ongoing psychological and behavioral patterns seen in the Dependency/Addiction Phase.
