Chapter 5: Health-Compromising Behaviors: Alcoholism and Smoking

Health-compromising behaviors share common features including emergence during adolescent vulnerability windows, strong ties to peer influences and identity formation, and gradual progression from experimentation to habitual use or addiction. These behaviors often function as maladaptive coping mechanisms for stress and psychological distress. Substance dependence develops through repeated use and involves tolerance, craving, and withdrawal syndromes. Alcoholism and problem drinking represent distinct phenomena: alcoholism involves physical addiction with withdrawal symptoms, while problem drinking causes substantial harm without necessarily meeting addiction criteria. Approximately 79,000 deaths annually result from alcohol-related causes, with significant economic burden. Two critical vulnerability periods exist for problematic drinking: adolescence through early adulthood and late middle age. Treatment approaches range from self-recovery through natural maturation to formal interventions including detoxification, cognitive-behavioral therapy, stress management, and medications that block alcohol's rewarding effects. Success rates correlate strongly with socioeconomic stability and social support, ranging from 68 percent in stable populations to substantially lower rates in disadvantaged groups. College-specific interventions emphasize self-control development rather than abstinence messaging, employing normative feedback and lifestyle modification. Smoking represents the leading preventable cause of mortality, claiming approximately 443,000 lives annually. Nicotine's powerful addictive properties stem from neurochemical effects on dopamine and acetylcholine regulation. Smoking demonstrates synergistic effects with other health risks, multiplying danger when combined with factors like high cholesterol or depression. Adolescent smoking initiation involves social contagion and identity formation processes. Treatment involves nicotine replacement strategies and behavioral interventions, though relapse rates remain high due to the abstinence violation effect. Prevention through behavioral inoculation during school years and social engineering approaches such as taxation, litigation, and workplace bans represent evidence-based strategies for reducing smoking prevalence and exposure to secondhand smoke.
