What additional factors can affect a person's level of intoxication?

Psychology and experience significantly influence a person's level of intoxication. A person's mindset, expectations, and emotional state can affect how they perceive and react to alcohol consumption. For instance, if an individual believes that they can handle alcohol well or is in a celebratory mood, they may drink more than they usually would, leading to a higher level of intoxication.

Experience plays a role as well; individuals who drink frequently may develop a higher tolerance to alcohol over time, which means they may not feel the effects of alcohol as strongly as someone with less experience. This is vital for servers and sellers to understand, as it emphasizes the need for responsible service, taking into account the varying effects of alcohol on different patrons based on their psychological state and drinking history.
