Review Questions

• How does heroin interact with the brain's reward system, and what implications does this have for addiction?
  • Heroin interacts with the brain's reward system by binding to opioid receptors, leading to an increase in dopamine levels that create feelings of euphoria. This intense pleasure reinforces drug-seeking behavior, making individuals more likely to continue using heroin despite negative consequences. The powerful impact of heroin on the reward pathway is a key reason why addiction develops so quickly and profoundly among users.
• Evaluate the effectiveness of naloxone as a harm reduction strategy in addressing heroin overdoses within communities.
  • Naloxone has proven to be an effective harm reduction strategy in preventing fatal overdoses from heroin by quickly reversing the effects of opioids when administered. It is often made available in community settings and can be administered by laypersons, increasing accessibility. While naloxone saves lives, it must be part of a broader strategy that includes treatment for substance use disorder and education on safe drug practices for it to be fully effective.
• Synthesize information about the rise of heroin use in relation to prescription opioid misuse and discuss its broader societal implications.
  • The rise of heroin use has been closely tied to the misuse of prescription opioids as users seek cheaper alternatives when prescriptions become harder to obtain or more regulated. This transition has led to a public health crisis characterized by increased addiction rates, rising overdose deaths, and greater societal costs related to healthcare and law enforcement. Understanding this relationship highlights the need for comprehensive strategies that address both prescription practices and the availability of illicit drugs like heroin.
