A habitually addicted individual is someone who is addicted to the regular consumption of alcohol; they can no longer control it. States have different definitions of the term. Simply serving an individual many alcoholic beverages does not necessarily make them habitually addicted.
In Florida, for example, habitually addicted refers to a person whose habit of indulging in alcohol is so fixed that they cannot resist getting drunk anytime the opportunity is present; intoxication is excessive and frequent.
The courts indicated that victims may introduce circumstantial evidence to show that a vendor knew the person they served was habitually addicted. Obtaining this type of evidence can, however, may require a knowledgeable personal injury lawyer.
