What is alcohol?

Ethyl alcohol, or ethanol, is an intoxicating ingredient found in beer, wine, and liquor. Alcohol is produced by the fermentation of yeast, sugars, and starches.

How does alcohol affect a person?

Alcohol affects every organ in the body. It is a central nervous system depressant that is rapidly absorbed from the stomach and small intestine into the bloodstream. Alcohol is metabolized in the liver by enzymes, however, the liver can only metabolize a small amount of alcohol at a time, leaving the excess alcohol to circulate throughout the body. The intensity of the effect of alcohol on the body is directly related to the amount consumed.

Why do some people react differently to alcohol than others?

Individual reactions to alcohol vary, and are influenced by many factors, including but not limited to

• Age.
• Gender.
• Race or ethnicity.
• Physical condition (weight, fitness level, etc).
• Amount of food consumed before drinking.
• How quickly the alcohol was consumed.
• Use of drugs or prescription medicines.

What is a standard drink in the United States?

A standard drink is equal to 13.7 grams of pure alcohol or

• 12-ounces of beer.
• 8-ounces of malt liquor.
• 5-ounces of wine.
• 1.5-ounces or a "shot" of 80-proof distilled spirits or liquor (gin, rum, vodka, whiskey, etc).

Is beer or wine safer to drink than liquor?

No. One 12-ounce beer has about the same amount of alcohol as one 5-ounce glass of wine, or 1.5-ounce shot of liquor. It is the amount of ethanol consumed that affects a person most, not the type of alcoholic drink.

What does moderate drinking mean?

There is no one definition of moderate drinking, but generally the term is used to describe low-risk or responsible drinking. According to the Dietary Guidelines for Americans, drinking in moderation is defined as having no more than 1 drink per day for women and no more than 2 drinks per day for men. This definition is referring to the amount consumed on any single day and is not intended as an average over several days.

No, alcohol use slows reaction time and impairs judgment and coordination, all skills needed to drive a car safely. The more alcohol consumed, the greater the impairment.

What does it mean to be above the legal limit for drinking?

The legal limit for drinking is the alcohol level above which an individual is subject to legal penalties (e.g., arrest or loss of a driver's license).

• Legal limits are measured using either a blood alcohol test or a breathalyzer.

• Legal limits are typically defined by state law, and may vary based on individual characteristics such as age and occupation.

All states in the United States have adopted 0.08% (80 mg/dL) as the legal limit for operating a motor vehicle for drivers aged 21 years or older. However, drivers under age 21 years are not allowed to operate a motor vehicle with any level of alcohol in their system.

How do I know if it's okay to drink?

The current Dietary Guidelines for Americans recommend that if you choose to drink alcoholic beverages, you do not exceed 1 drink per day for women and 2 drinks per day for men. These guidelines also specify that there are some people who should not drink alcoholic beverages at all, including

• Children and adolescents.
