Information about medical students' lifestyles was obtained from 785 s
econd-year students from seven medical schools in Great Britain by a p
ersonally administered questionnaire. Fifteen per cent of the students
were non-drinkers. Among those who drank, 48% of the men and 38% of t
he women exceeded sensible weekly limits of alcohol consumption, and h
igh-risk levels of consumption were reported by 12% of men and 7% of w
omen. Cannabis had been used at least once or twice by more than half
the men and 40% of the women, and 10% reported regular use (weekly or
more often). Experience with other illicit drugs was also reported: am
phetamines (8% of students), LSD (7%), ecstasy (4%), amyl/butyl nitrat
e (10%) and magic mushrooms (7%). Nineteen per cent of the students ha
d used two or more different drugs. Experience with illicit drugs star
ted before entering university in more than a third of those who used
them. Comparison of the results with other student surveys suggests th
at the lifestyles of medical students differ little from those of othe
r student groups, but that alcohol and illicit drug consumption is inc
reasing in university students generally. Prospective studies are unde
r way to establish whether medical students change their lifestyles at
later stages of their course and after qualification.
