RESULTS
In our study population, 1.45 percent of all individuals
sought care for mental or behavioral disorders due to psychoactive
substance use in 2001. Alcohol was involved in
the diagnoses of 88 percent of those individuals, sedatives
or hypnotics 9 percent, stimulants 7 percent, and opioids
6 percent. Fourteen percent of those individuals with a disorder
had used multiple substances. Clinical conditions constituted
a dependence syndrome for 91 percent and harmful
use for 13 percent of the individuals.
