What is the primary focus of substance abuse?

Substance abuse primarily refers to the overindulgence or excessive use of drugs, alcohol, or other psychoactive substances. This concept encompasses not just the amount consumed but also the impact those substances have on an individual's life. The activities associated with substance abuse often lead to harmful consequences, such as addiction, health problems, and impaired social functionality.

While factors like social and emotional health, financial stability, and physical training can all be affected by or contribute to substance abuse, they are not the main focus of the concept. Substance abuse is fundamentally about the consumption of substances and the consequences that arise from this behavior, making the emphasis on overindulgence in chemicals the most accurate and relevant understanding.
