students (36.2%) reporting ever having smoked a cigarette. However, 421 students (20.5%) also reported having smoked cigars in the past month, and 548 (26.7%) reported hookah use in the past month. With respect to other drug use, 837 (40.7%) of students reported ever using cannabis, 132 (6.4%) reported ever using sedatives, 217 (10.6%) reported ever using stimulants, 77 (3.7%) reported ever using cocaine, and 93 (4.5%) reported ever using opioids. Table 3 shows the intercorrelations between the substance use variables. Ever use of alcohol was most highly correlated with ever use of cannabis and cigarettes. Higher frequency/quantity of alcohol use was associated with increased likelihood of using other substances. Ever use of cigarettes was more highly correlated with use of illicit drugs other than cannabis than ever use of alcohol was at this age. Use of cigarettes or cannabis were about equally correlated with use of other illicit drugs. Additionally, use of any of the other illicit drugs was most strongly correlated with use of other forms of illicit drugs.
