An anonymous reader writes with news of a study out of the University of Florida which found that alcohol is the biggest "gateway" drug, the use of which increases the likelihood of other drug use. Quoting: "In the sample of students, alcohol also represented the most commonly used substance, with 72.2 percent of students reporting alcohol consumption at some point in their lifetime. Comparatively, 45 percent of students reported using tobacco, and 43.3 percent cited marijuana use. In addition, the drug use documented found that substance use typically begins with the most socially acceptable drugs, such as alcohol and cigarettes, then proceeds to marijuana use and finally to other illegal, harder drugs. Moreover, the study showed that students who used alcohol exhibited a significantly greater likelihood — up to 16 times — of licit and illicit substance use."
