Alcoholics may have a distinct odor on their breath, clothes, or body due to the consumption of alcohol. This odor can be noticeable to others and may become a source of embarrassment or shame for the person struggling with alcoholism. Additionally, heavy alcohol use can affect personal hygiene, leading to body odor or bad breath. However, it is important to note that not all alcoholics will have a noticeable odor, and there can be many other factors that contribute to body odor or bad breath.
