This study examines which personal student background and college char
acteristics are associated with marijuana use. A self-administered sur
vey was mailed to a national representative sample of 17 592 students
at 140 American colleges. One of four (24.8%) students reported wing m
arijuana within the past year. Rates of use among the colleges ranged
from zero per cent at the lowest we schools to 54% at the highest use
schools. Multiple regression models, constructed to determine the coll
ege and student characteristics predicting marijuana we, suggest that
use was higher among students at non-commuter colleges and at colleges
with pubs on campus. Student characteristics associated with marijuan
a we included being single, white, spending more time at parties and s
ocializing with friends, and less time studying. Marijuana use was hig
her among students who participate in other high risk behaviors such a
s binge drinking, cigarette smoking and having multiple sexual partner
s, and among students who perceived parties as important, and religion
and community service as not important. The study points to the socia
l nature of drug use in college, and demonstrates that this behavior i
s of continuing concern for public health.
