Study Notes
Health Effects of Tobacco
- Lung cancer incidence is significantly higher (10-fold) in asbestos workers who smoke compared to non-smokers.
- Approximately 30,000 to 60,000 cardiac deaths annually in the U.S. are associated with passive smoke exposure.
- Children in households with smokers face higher respiratory illnesses and asthma risks.
- Cotinine blood levels can measure passive smoke inhalation among non-smokers; median levels dropped over 60% due to public non-smoking policies.
- Almost one-third of heart attacks are linked to cigarette smoking, with long-term health repercussions outweighing brief pleasure from smoking.
- Tobacco smoke is a contributor to multiple cancer types, including the oral cavity, larynx, esophagus, pancreas, and bladder.
Alcohol Metabolism and Smoking
- Blood alcohol levels determine drowsiness, stupor, or coma: 200 mg/dL indicates drowsiness, 300 mg/dL stupor, and higher levels can cause respiratory arrest.
- Chronic alcoholics can tolerate blood alcohol levels up to 700 mg/dL due to accelerated metabolism.
- Alcohol metabolism primarily occurs via alcohol dehydrogenase, with high levels also engaging cytochrome P-450 enzymes.
Risks Associated with Smoking
- About 90% of lung cancers occur in smokers, and they are also at increased risk for several other cancers, including leukemia.
- Quitting smoking significantly reduces lung cancer risk, even if cessation occurs at age 60.
- Smokeless tobacco is a significant cause of oral cancers.
Lead Poisoning and Environmental Pollutants
- Lead exposure continues through contaminated air, food, and hazardous materials despite historical reductions from lead paint and gasoline.
- Children's primary risks come from flaking lead paint, where even small paint chips can lead to toxic lead levels.
- Symptoms of lead exposure vary: adults may experience headaches and memory loss, while children may suffer from encephalopathy and developmental issues.
Global Impact of Smoking
- Smoking-related deaths exceed 1 million annually in China, highlighting the global health crisis.
- Components of cigarette smoke, such as polycyclic hydrocarbons and nitrosamines, are potent carcinogens, contributing to lung cancer risk.
- The intensity of smoking is often measured in "pack years," linking higher exposure to increased disease risk.
