Which of the following is a sign of potential alcohol use disorder?

The presence of an inability to stop drinking despite experiencing negative consequences is a clear indicator of potential alcohol use disorder. This behavior reflects a loss of control over drinking habits, which is a key characteristic of addiction. Individuals facing this issue may continue to consume alcohol even when it leads to problems in various areas of their lives, such as health, relationships, or professional responsibilities.

In contrast, occasional social drinking, strict control over the frequency of drinking, and moderate use of alcohol do not typically signify addiction. These behaviors may reflect responsible drinking patterns that do not indicate a problematic relationship with alcohol. Thus, the inability to stop drinking regardless of adverse effects distinctly highlights a potential disorder that requires assessment and intervention.
