Which intervention would primarily assist users in returning to a healthier state?

The intervention that primarily assists users in returning to a healthier state is tertiary prevention. This level of prevention is focused on managing and reducing the impact of an existing health condition or disease after it has occurred. In the context of substance use or addiction, tertiary prevention involves strategies aimed at rehabilitation, recovery programs, and ongoing support to prevent relapse, thereby helping individuals regain their health and functioning.

In contrast, primary prevention aims to prevent the onset of a problem or condition before it occurs, such as through education or lifestyle modifications to avoid substance use. Secondary prevention focuses on early detection and intervention in the early stages of a condition, such as screening for substance use disorders before they become severe. Cross-dependence refers to a situation where one substance can replace the physiological effects of another, which is not a treatment approach.

Tertiary prevention is critical for individuals who have already faced the consequences of addiction, as it emphasizes support and therapeutic interventions that help them restore their well-being and reintegrate into society.
