What best describes a common theme across substance-related disorders?

A common theme across substance-related disorders is the significant impairment in functioning that accompanies addiction. This impairment can manifest in various aspects of life, including personal relationships, occupational responsibilities, and overall health. The disorder often leads to a pattern of behavior where the individual continues to use the substance despite the negative consequences that arise, showcasing the severe impact it has on their daily functioning and quality of life.

While some may think of dependence as a purely physiological or psychological experience, the consequences of substance misuse typically lead to tangible harm in an individual’s life, reinforcing the notion that addiction is not merely about the substance itself but rather the broader implications of addiction on an individual’s life and their ability to function effectively within it.
