What behavioral pattern is indicative of substance/chemical dependence?

The behavioral pattern indicative of substance or chemical dependence is consistent, periodic intoxication. This pattern suggests that an individual frequently engages in substance use to the point of intoxication, which can disrupt their daily life and responsibilities. Dependence often involves a psychological and physical reliance on the substance, leading the individual to prioritize substance use over other activities or responsibilities.

In contrast, intermittent usage with long breaks may indicate occasional use rather than dependence. Frequent social interactions without substance consumption reflect a healthy engagement in social activities that do not rely on alcohol or drugs, suggesting a lack of dependence. Minimal consumption to maintain functionality might indicate an unhealthy relationship with a substance, but it does not necessarily represent the regular, problematic use associated with dependence as seen in consistent, periodic intoxication. Thus, the described behavior in option B most clearly aligns with the patterns seen in individuals diagnosed with substance dependence.
