Alcohol is a very powerful, addictive drug that is damaging or even lethal in high doses. Many adults drink moderately and safely. Yet other people drink too much and get hurt. For teens, alcohol can be very harmful -- and it's illegal.
Check out the following Q&A to update your knowledge of alcohol and teen drinking. Share this information with a friend, especially if you know someone who is an underage drinker.
The scientific name for alcohol that people drink is ethyl alcohol or ethanol. Beer, wine, and liquor all contain ethyl alcohol. Other types of alcohol, like rubbing alcohol (isopropyl alcohol), are poisonous if consumed.
What Happens When You Drink Alcohol?
After you drink an alcoholic beverage like beer or wine, the alcohol enters your bloodstream from your stomach and small intestine. From there, it travels to your brain. There, it slows reaction time, makes you less coordinated, impairs your vision, and -- even at relatively low doses -- leads to unclear thinking and problems making good judgments.
Is Alcohol Addictive?
Yes, alcohol is highly addictive. About 18 million adults are addicted to alcohol. This means they need to drink alcohol in order to function normally, and their drinking causes problems in their lives.
Alcohol addiction can begin at any time in someone's life. But starting to drink when you are a teenager increases the risk for addiction. Teens who start drinking alcohol before age 15 are five times likelier to develop a later addiction to alcohol than those who begin drinking at age 21 or older.
Is One Type of Alcoholic Drink Safer than Another?
No. All alcoholic drinks contain alcohol, and all can be just as dangerous. The more alcohol you drink, the more you will be impaired. Beer, wine, and liquor all contain different amounts of alcohol. Beer is between 3% and 5% alcohol; wine is about 12%; and liquor usually is about 40% alcohol. One beer has about the same amount of alcohol as one glass of wine or one "shot" of liquor.
Why Do People Drink Alcohol?
Drinking alcohol is a social activity -- most people drink with friends. Because alcohol makes people feel less inhibited, they feel more at ease socializing when they drink. People also drink just because other people are drinking. For many people, it feels good to be doing what everybody else is doing. But drinking just because everybody else is drinking can lead to problems, especially if people are drinking too much.
On the other hand, many people enjoy the taste of alcoholic beverages. And when consumed by adults in small to moderate amounts, especially with meals, alcohol may be good for the heart.
