What is a common symptom of drug or alcohol abuse?

Feeling guilt about substance use is a common symptom of drug or alcohol abuse because individuals often experience emotional turmoil as a result of their actions related to substance use. This guilt can stem from various factors, such as neglecting responsibilities, affecting relationships, or compromising personal values. Even if someone continues to use the substance, these feelings can create a cycle of shame and further compulsion to use, as they might feel that the substance is the only thing providing temporary relief from their emotional pain. This emotional struggle is a significant indicator of problematic substance use and can lead to further psychological issues if not addressed.

In contrast, the other choices reflect positive outcomes or behaviors that are generally not associated with substance abuse. For example, success in managing stress and increased physical fitness are indicators of a healthy lifestyle, while positive interpersonal relationships reflect the ability to maintain healthy connections with others. These traits are often compromised in individuals struggling with substance abuse, making them unlikely symptoms of such use.
