What is the difference between substance use and substance use disorder?

Substance use and substance use disorder represent different concepts in the realm of addiction and psychological health. Substance use refers to the consumption of alcohol or drugs, which can vary in frequency, amount, and context. It may be casual or recreational and does not necessarily lead to negative outcomes. On the other hand, substance use disorder is characterized by a problematic pattern of substance use that leads to significant impairment or distress. This can manifest through various criteria, such as an inability to control use, continued use despite harmful consequences, or a strong craving for the substance.

The distinction lies in the severity and impact on an individual's life. While substance use can be part of normal social activities and may not always have negative ramifications, a substance use disorder implies that the individual's relationship with the substance has become problematic and harmful, affecting their daily functioning, relationships, and overall well-being. This differentiation is crucial for treatment and support strategies, as recognizing someone with a substance use disorder allows for targeted interventions to address the specific challenges they face.
