Alcohol related statisticsAlcohol related statistics Every day in America, another 28 people die as a result of
drunk driving crashes. In 2012, 29.1 million people admitted to driving under the
influence of alcohol - that’s more than the population of Texas.
High school students who use alcohol or other substances are five times more likely to drop out of school.
Kids who start drinking young are seven times more likely to be in an alcohol-related crash.
Car crashes are the leading cause of death for teens, and about a quarter of those crashes involve an underage drinking driver
Teen alcohol use kills 4,700 people each year - that’s more than all illegal drugs combined
On average, two in three people will be involved in a drunk driving crash in their lifetime

FoodFood
BeerBeer
The amount of food in your stomach does very little to reduce the effect alcohol has on the brain and liver.
However, food does coat the lining of the stomach and slows absorption into the blood stream.
Note: When alcohol is mixed with carbonated beverages the absorption rate is faster because gases are absorbed faster than liquids.
