title: Psychoactive substance use and dependence among Spanish university students: prevalence, correlates, polyconsumption, and comorbidity with depression.
abstract: In this study, the prevalence of psychoactive substance use and dependence was estimated among students at a Spanish university, together with associated factors, polyconsumption, and comorbidity with depression, using a 554-member sample stratified by sex, degree year, and discipline. 86.5% had consumed some potentially addictive psychoactive substance in the past month, and 10.5% satisfied DSM-IV criteria for dependence on nicotine, alcohol, caffeine, or cannabis. Polyconsumers (90.4%) consumed an average 3.2 different substances. Current depression implied increased likelihood of having consumed tobacco or psychoactive pharmaceutical drugs in the past month, and DSM-IV symptoms of major depressive episode were shown by 8.6% of 58 substance-dependent participants, 8.7% of 540 past-month legal substance consumers, and 12.1% of 140 past-month illegal substance consumers.
