What psychological factor can play a role in a person's intoxication level?

Mood is a significant psychological factor that can influence a person's level of intoxication. When individuals are in a positive or relaxed mood, they may be more likely to engage in drinking behaviors, sometimes consuming alcohol more quickly or in larger quantities. Conversely, if someone is in a negative mood, they might also drink excessively as a form of coping. Additionally, mood can impact how alcohol affects the body; for instance, emotional states can either amplify or dull the effects of alcohol depending on the individual's experiences and mental state. Understanding this relationship helps servers and sellers recognize how customers' emotional conditions can affect their alcohol consumption and safety.
