Study Notes
Blood Alcohol Level and Impairment
- A blood alcohol level of 0.05 percent or higher causes some driving impairment
- In all U.S. states, a blood alcohol level of 0.10 percent or higher constitutes driving under the influence
Alcohol Metabolism
- Alcohol is metabolized at a relatively constant rate depending on the drinker's body weight
- A 150-pound person metabolizes approximately three-quarters to one ounce of alcohol per hour
Prevalence of Alcohol Use in the United States
- In 2004, about 50.3 percent of Americans aged 12 or older (an estimated 121 million people) reported being current drinkers of alcohol
- Approximately 16.9 million Americans (6.9 percent of the population) reported heavy drinking in 2004
Effects of Alcohol on Cognitive and Motor Functions
- Moderate doses of alcohol impair physical coordination and mental agility, affecting tasks like driving a car.
- Larger doses alter perception, causing staggering, blurred vision, and symptoms of drunkenness.
Individual Reactions to Alcohol Consumption
- People react differently to alcohol, with some becoming emotional or amorous, while others become aggressive and hostile.
Risks of Excessive Alcohol Consumption
- Extremely high doses, typical during binges, can cause depression of the central nervous system.
- This can lead to cessation of bodily functions, including breathing, and potentially result in death.
