In terms of annual prevalence, more than twice as many students drank as used tobacco, but daily use of tobacco was 15 times higher than daily use of alcohol. Table 4.6 summarizes the annual prevalence of the six most frequently used drugs, in order of use. These figures represent a more immediate and shorter-term picture of students' substance use patterns than the annual prevalence figures noted above, and accordingly the percentages are lower than the annual prevalence figures. Alcohol, tobacco, and marijuana were the most frequently used drugs, followed by amphetamines, hallucinogens, and cocaine. Consequences Table 4.8 lists the self-reported consequences of alcohol and other drug use during the last year.
Several findings are relevant to the academic environment.
Note that 37.0 percent of the students reported activities under the influence of alcohol or other drugs that they later regretted, 30.5 percent had a fight or argument, and 13.2 percent reported being physically hurt or injured as a consequence of substance use. By gender, 14.7 percent of the men believed that they had a substance abuse problem as compared to 7.7 percent of the women, and 17.1 percent of the men had been in trouble with police or other campus authorities compared to only 7.7 percent of the women. A substantial contrast exists between the 34.8 percent of students who had driven under the influence and the 1.2 percent who had been arrested for drunk driving. Alcohol Use and Academic Performance Table 4.9 describes the relationship between the average number of drinks consumed per week and grade average. As can be seen, the heaviest drinkers obtained the lowest grades.
