Background and objectives: Drug misuse among young people has become a major worldwide health concern. The present study analyzes substance misuse and its social and personal consequences in young university students. Materials and Methods: Screening of alcohol misuse was based on the Alcohol Use Disorder Identification Test (AUDIT), while screening of substance-related risks and problems was performed with the Car, Relax, Alone, Forget, Friends, Trouble (CRAFFT) score. Results: The population was composed of nursing students at the University of Valencia (Valencia, Spain) (n = 185). More than 50% of the surveyed students reported alcohol intake based on the CRAFFT scale; 31.4% were classified as having "risky alcohol use", and 19.5% met the criterion for hazardous drinking based on the AUDIT score. In turn, 34.1% of the sample reported marijuana/hashish intake based on the CRAFFT scale. A gender effect was only observed for marijuana/hashish use, which was significantly (p < 0.001) higher in male students. No other gender differences were observed. In the logistic regression analysis, only age was identified as a protective factor for obtaining a reduced risk score with both the AUDIT and the CRAFFT. Among the social and personal consequences of drug misuse, the inability to "stop drinking once you have started" or the inability to "remember what happened while consuming" was significantly associated with an increased frequency of alcohol consumption (OR 20.93, p < 0.0001 and OR 13.68, p < 0.05, respectively). Conclusions: Our findings are consistent with emerging social concerns about drug misuse in the university population, including nursing students as future healthcare professionals.
