(4) Heroin - opioid causing severe physical and psychological dependence. (5) Cocaine - stimulant producing intense euphoria and addiction.

Smoking health effects: Respiratory system - (1) Damages lung alveoli reducing oxygen absorption. (2) Increases mucus production causing chronic cough. (3) Increases risk of lung cancer, bronchitis, emphysema, asthma. Cardiovascular - (1) Nicotine increases heart rate and blood pressure. (2) Carbon monoxide reduces oxygen in blood. (3) Increases atherosclerosis and blood clots. (4) Heart attack and stroke risk increases. Other - (1) Weakens immune system increasing infections. (2) Reduces bone density increasing fracture risk. (3) Causes premature aging of skin. (4) Reduces fertility and harms fetus in pregnancy. (5) Second-hand smoke equally harmful.

Stress effects: Physical health - (1) Triggers fight-or-flight response releasing cortisol and adrenaline. (2) Increases heart rate and blood pressure. (3) Weakens immune system - susceptibility to infections increases. (4) Causes insomnia disrupting sleep quality and recovery. (5) Muscle tension leading to headaches and back pain. (6) Digestive problems - ulcers, irritable bowel syndrome. (7) Long-term stress causes cardiovascular disease and diabetes. Mental health - (1) Anxiety and panic attacks. (2) Depression and low mood. (3) Poor concentration and memory. (4) Irritability and mood swings. (5) Burnout and mental exhaustion. Management - Exercise, meditation, social support, counseling, adequate sleep.

Immunization - introduction of vaccine to stimulate immune response against specific pathogens. How it works - (1) Vaccine contains weakened or inactivated pathogen or its antigen. (2) Immune system produces antibodies against the pathogen. (3) Memory B cells and T cells develop long-term immunity. (4) Upon exposure to actual pathogen, immune system quickly recognizes and destroys it. (5) Prevents disease or reduces severity. Types - (1) Live attenuated - weakened pathogen (MMR, chickenpox). (2) Inactivated - killed pathogen (polio, hepatitis). (3) Subunit - specific pathogen proteins (flu, hepatitis B). (4) mRNA - instructs cells to make pathogen protein (COVID-19). Benefits - Prevents pandemics, reduces mortality, creates herd immunity.

Social health - ability to interact effectively with others and maintain meaningful relationships within society. Components - (1) Strong interpersonal relationships with family and friends.

(2) Limit alcohol consumption. (3) Avoid drug use. Regular checkups - (1) Monitor blood pressure, cholesterol, blood sugar. (2) Early detection of diseases enables treatment.

Public health initiatives: Disease control - (1) Vaccination programs create herd immunity and prevent epidemics. (2) Sanitation and clean water projects prevent waterborne diseases. (3) Disease surveillance systems detect outbreaks early. Health education - (1) Teaching nutrition, hygiene, disease prevention in schools. (2) Public campaigns on smoking, alcohol, drug dangers. (3) Maternal and child health education reducing mortality. Access to healthcare - (1) Clinics and hospitals in rural areas. (2) Subsidized or free medical services for poor populations. (3) Trained healthcare workers availability. Environmental health - (1) Air quality monitoring and pollution control. (2) Proper waste management. (3) Occupational safety standards. Community engagement - (1) Local participation in health planning. (2) Health awareness through community organizations. (3) Peer education programs. Results - Increased life expectancy, reduced disease burden, improved quality of life.
