A person who drinks alcohol is often referred to as a "drinker" or "social drinker." The term "drinker" is a broad and neutral description that can apply to anyone who consumes alcohol, regardless of the frequency or amount of alcohol they consume. Additionally, someone who occasionally drinks alcohol in social settings but not to excess may be specifically described as a "social drinker."
It's worth noting that when discussing alcohol consumption, it's important to recognize that individuals have different relationships with alcohol. Some people may choose not to drink at all (teetotalers), while others may drink in moderation, and some may struggle with excessive or problematic drinking (alcoholism or alcohol use disorder). Understanding and respecting these individual differences is crucial when discussing alcohol and its impact on people's lives.
