**Core Concept**
The maintenance of substance dependence involves the use of medications to manage withdrawal symptoms, cravings, and prevent relapse in individuals with a history of substance use disorder. This approach aims to reduce the risk of overdose, improve quality of life, and facilitate long-term recovery.

**Why the Correct Answer is Right**
The correct answer involves medications that act on the brain's reward system, neurotransmitter pathways, or opioid receptors to reduce cravings and alleviate withdrawal symptoms. For example, methadone, buprenorphine, and naltrexone are commonly used medications in the maintenance of opioid dependence. Methadone and buprenorphine are opioid agonists that activate opioid receptors, while naltrexone is an opioid antagonist that blocks opioid receptors. These medications help reduce withdrawal symptoms and cravings, making it easier for individuals to maintain sobriety.
