Patterns of alcohol consumption, smoking and illicit drug use in British university students: interfaculty comparisons.

The use of tobacco, alcohol and illicit drugs was investigated by questionnaire in 3699 second year students in ten UK universities. Patterns of use varied considerably between different faculty groups. Tobacco use was most prevalent in arts, social science and biological science students, among whom 36-39% of men and nearly one third of women were regular smokers, and least in female veterinary students (5%). Alcohol consumption was greatest in biological science students: 23% of those who drank exceeded 'hazardous' levels compared with 10-16% in all other faculties. Prevalence of cannabis use was highest in arts and social science students of whom 27% reported regular weekly use compared with 9-22% in other faculties. Experience with other illicit drugs was greatest among arts, social science and physical science students, of whom 64-71% reported experience at least once or twice, and least among veterinary students (42%). Identification of different lifestyles may help to direct appropriate health information to particular student groups.
