What does substance misuse refer to?

Substance misuse refers to the excessive or inappropriate use of drugs or alcohol that can lead to negative consequences in one's life, including health problems, social issues, and conflicts in personal relationships. This definition aligns with the concept of conflict avoidance, as individuals may use substances as a coping mechanism to escape from problems or stressors. Misuse often results in an inability to manage life's challenges effectively, leading to behavioral patterns that can exacerbate existing issues.

The other options describe scenarios that do not align with the definition of misuse. Responsible use signifies moderation and control, occasional use without issues implies that the use does not impact one's life negatively, and complete abstinence does not involve substance use at all. Thus, these choices do not capture the essence of substance misuse as it's characterized by excessive consumption and the complications that arise from that behavior.
