Substance abuse, dependence, and addiction constitute a significant public health concern worldwide, with high incidence and prevalence rates across diverse populations. According to the World Health Organization (WHO, 2018), an estimated 5.3% of the global population suffers from substance use disorders (SUDs). These disorders are characterized by a range of maladaptive patterns related to the use of substances such as alcohol, opioids, stimulants, and others, leading to clinically significant impairment or distress. The prevalence varies by geographic region, demographic factors, and socio-economic status, with higher rates observed among young adults and marginalized populations (Grant et al., 2017). Understanding the pathophysiology from an Advanced Practice Registered Nurse (APRN) perspective involves examining neurobiological mechanisms, including the role of neurotransmitter dysregulation in reward pathways, notably the mesolimbic dopamine system (Volkow & Morales, 2015). Substance use induces pleasurable sensations by increasing dopamine release, which reinforces repeated use and contributes to dependence. Chronic substance use further alters neural circuits, impairing executive function and decision-making, facilitating compulsive behavior characteristic of addiction. Physical assessment and examination of patients with substance use disorders should include comprehensive behavioral and physiological evaluations. Clinicians should look for signs such as needle marks, malnutrition, hepatic or cardiovascular manifestations, and behavioral indicators like agitation or confusion. Laboratory tests, including blood alcohol levels, liver function tests, and toxicology screens, aid in diagnosis and monitoring (SAMHSA, 2016). An evidence-based treatment plan encompasses pharmacologic interventions such as methadone, buprenorphine, or naltrexone for opioid dependence, along with behavioral therapies including cognitive-behavioral therapy (CBT), contingency management, and motivational interviewing. Patient education should focus on understanding the nature of addiction, risks of relapse, and strategies for maintaining sobriety. Continuous follow-up is crucial to evaluate treatment efficacy, employing tools like standardized scales (e.g., Addiction Severity Index) and regular physical assessments to monitor health status, engagement, and relapse prevention. Managing episodic, acute, and chronic phases requires tailored interventions—acute detoxification protocols, ongoing maintenance therapy, and long-term psychosocial support—aimed at reducing harm and restoring functional independence (Miller & Rollnick, 2013). Overall, a multidisciplinary approach integrating medical, psychological, and social support systems is vital for optimizing outcomes in individuals with substance use disorders.
