1. Alcohol is toxic to the human body.

1. TRUE There is a limit to how much alcohol the human body can tolerate. When you drink too much, your blood alcohol level can rise to a point where it actually becomes poisonous.

3. Alcohol, food, and non- alcoholic beverages are all digested the same way.

3. FALSE Alcohol is not digested like other foods or beverages. It passes directly into the bloodstream through the tissue that lines the stomach and small intestine.

5. Alcohol doesn't affect your body's organs unless you get really drunk.

. FALSE When you have an empty stomach, alcohol is absorbed into the bloodstream through the small intestine within about five minutes. As soon as it's in the bloodstream, it takes about 90 seconds for it to be carried to all of the body's organs, including the brain. So you don't have to be drunk for your whole body to be feeling alcohol's effects.

8. Passing out can be life threatening.

8. TRUE If you drink so much that you pass out, it's because the alcohol has caused your brain to start shutting down, resulting in your loss of consciousness. The amount of alcohol it takes to make you pass out is dangerously close to the amount of alcohol it takes to kill you.

10. Even though alcohol is a drug, you can't overdose on it.

10. FALSE When you drink too much, that's the same thing as overdosing on alcohol. Alcohol is a depressant drug that slows the central nervous system, decreasing your heart and breathing rates and lowering your blood pressure. A dangerously high blood alcohol level can cause your heartbeat and breathing to stop altogether, which means you can die from drinking too much.

11. Your family history can influence your drinking habits

11. TRUE Children of alcoholics are three to four times more likely to become alcoholics themselves. So if you've got a family history of heavy alcohol use, you are at a greater risk of developing alcohol problems.

12. Every time you drink alcohol, you kill 10,000 brain cells.

12. FALSE Not exactly. It's unlikely that a single drink will kill brain cells. However, long-term, chronic drinking can cause permanent memory loss and brain damage. Almost 70% of people in treatment for alcohol-related problems suffer severe impairment of memory formation, abstract thinking, problem solving, and ability to concentrate.
