text: [Epidemiology of alcohol and drug abuse in Paraguay].
  The results of a prevalence study on use- and abuse- of psychoactive substances, among a population aged 12 to 45 in Paraguay are presented. Presence of the depressive syndrome as well as attitudes and beliefs related to the use of psychoactive substances were also investigated. A bilingual questionnaire was drafted--i.e. a Spanish version and a Guarani version due to the Paraguayans' bilingual characteristic--that yielded acceptable validity and reliability levels. A stratified random sample was applied, with a total of 2,504 questionnaires filled out. Weighted data are shown here as studied by sex, age-group, socio-economic level, and presence of the depressive syndrome. Substance/alcohol use patterns were found out to be widely tolerant about abusing legal substances such as alcohol, tobacco, and psychotropic drugs. As regards illicit substances use, inhalants head the list followed by marijuana at a close range.
