Table 4 shows the prevalence of college students whose
ASSIST-WHO scores suggest hazardous drug use for each
investigated drug by age. Student age was associated with
the development of the hazardous use of alcohol (p < 0.05),
marijuana (p < 0.001), inhalants (p < 0.01), hallucinogens
(p < 0.05), ecstasy (p < 0.01), AAS (p = 0.053), tranquilizers
(p < 0.01) and amphetamines (p < 0.05). This pattern of
results was also observed for the use of drugs in the 30 days
prior to the interview.
