Why do teens drink? 66% cited stress and boredom, 25% said they drink to get high, and 31 percent said they drink alone. In 1989 3000 teens between the ages of 15 and 19 died in alcohol-related auto accidents. The favored drink among teenagers is wine coolers, but many choose beer because it is cheaper and easier to get. Students annually consume 35 percent of all wine coolers sold in the U.S. or 31 million gallons. They also consume 1.1 billion cans of beer, or 102 million gallons.
