What is the difference between substance use and substance abuse?

Substance use and substance abuse are part of a spectrum regarding how individuals interact with drugs and alcohol. The distinction highlighted in the correct answer emphasizes that substance use generally refers to the casual or non-problematic consumption of substances, where individuals engage in usage that does not result in negative consequences or impairment. This might include social drinking or taking prescribed medications as directed.

In contrast, substance abuse involves consuming these substances in a harmful manner, leading to negative consequences in various aspects of life, such as health, personal relationships, and responsibilities. This could manifest through compulsive use, increased tolerance, negative health outcomes, or detrimental effects on one's social or occupational functioning.

Understanding this difference is crucial for recognizing the potential risks associated with substance consumption and also for identifying individuals who may need help. Therefore, the distinction made in the correct answer clarifies how the context and impact of substance use can vary significantly from how substance abuse affects an individual’s life.
