What behavior is indicative of substance use disorder as per the DSM 5?

Experiencing withdrawal symptoms is a key indicator of substance use disorder as defined by the DSM-5. Withdrawal symptoms occur when an individual who has developed a physical dependence on a substance reduces or stops its usage, leading to a range of physical and psychological symptoms that can be quite uncomfortable or distressing. This physiological response highlights the body's adaptation to the substance, and its removal can lead to a significant negative impact on the individual's ability to function normally. A hallmark of substance use disorder is the inability to stop using a substance despite these withdrawal symptoms, which further signifies the disorder's impact on an individual's life.

In contrast, using medication as prescribed typically does not indicate a substance use disorder, as this reflects adherence to a treatment plan rather than misuse. Occasional cravings may occur in non-disordered users as well, as craving can happen without leading to problematic use. Engaging in recreational activities is generally not associated with substance use disorder, and in fact, many individuals engage in healthy recreational activities while maintaining sobriety or responsible substance use.
