What are heavy use with serious life problems classified as?

Heavy use with serious life problems is classified as dependency. This classification indicates that an individual is experiencing significant issues related to their alcohol or drug use, which can manifest in various forms such as physical, psychological, social, or legal problems. Dependency implies a level of impairment and a need for the substance, often accompanied by a lack of control over use, which aligns with heavy usage patterns that lead to serious life difficulties.

The other classifications do not fit this scenario. Moderate use represents a level of consumption where a person does not experience significant problems associated with their use. Non-problematic use signifies that the individual is using substances without any adverse consequences, which is contrary to the scenario of serious life problems. Heavy and non-problematic use creates a contradiction, as the term "heavy use" inherently suggests problematic behavior that would typically be accompanied by serious issues. Thus, the identification of heavy use alongside serious life problems most accurately aligns with dependency.
