Constitution
American
Prohibition Law
In 1920, an improvement was added to the Constitution. It made drinking or selling alcohol a crime. But the new law did not stop people from drinking. Criminals produced or imported alcohol illegally and sold it almost everywhere. After a few years Americans realized the so-called Prohibition Law did not work. So in 1933, another constitutional change was made, canceling the improvement that made alcohol illegal. In recent years, Americans have taken other steps to deal with the problem of alcohol. One important action had been to increase the punishment for people who drive their automobiles after drinking alcohol. Many states now consider this a serious crime. Another important step has been to explain to children and students the dangers of alcohol. Many schools now offer special programs to teach young people about the problem.
