Responses by the public to the question of whether drugs was the United States' most important problem ranged from under 5% to over 60% during the 9 years from 1985 to 1994. Time series analysis showed that changes in this opinion could be explained by the press describing drugs as a crisis. Other types of drug discussion contributed negligibly. In the reverse direction, public opinion about drugs was a weak but significant contributor to press coverage.
