More College Kids Smoke cigarettes Pot Now Than Smoking cigarettes.

Very few college students use heroin, the researchers noted, and use of the drug over the past five years on campuses was lower than in the late 1990s and early 2000s. nonmedical usage of tranquilizers decreased from almost 7 % in 2003 to 3.5 % in 2014, and rates useful of LSD and other hallucinogenic medications in 2014 were just over 2 % and 3 %, respectively. College students’ use of club drugs and bath salts have become low. And though drinking prices remain high even, rates of drunkenness fell in 2014. According to the study, the proportion of students who said that they had alcohol at least once during the past month fell from 82 % in 1981 to 67 % in 2000 also to 63 % in 2014. The proportion who said that they had gotten drunk in the last month also fell, from 48 % in 2006 to 43 % in 2014.We made no assumptions regarding missing data; all proportions had been calculated as %ages of the patients with available data. Statistical Analysis We performed statistical evaluation using SAS software, edition 9.1 . We calculated descriptive statistics for all study variables. We survey data for continuous variables as medians and for categorical variables as %ages . We estimated the age-centered population-admission rates.13 We performed a univariate evaluation for in-hospital mortality, using the chi-square test, Fisher’s exact check, or Wilcoxon rank-sum check, as appropriate.
