Drinking is a self-indulgence that only offers short-term pleasure. It is an individualistic behaviour that reduces the drinker's interest in others, while conversely increasing their desire for more alcohol. Alcoholism has been known to ruin marriages and end relationships, but it can also destroy a person's character and reputation. In some cases, drinking can lead to chaotic social behaviour that can even cause a person to break the law. In most cases of divorce, alcohol is usually involved as substance abuse has been blamed as one of the major causes of marital problems and family breakups.
