OBJECTIVE: to describe patterns of drugs, seroprevalences of HIV, hepatitis B (HBV), hepatitis C (HCV), syphilis and other health problems among coca paste users assisted at a drug treatment center in Argentina. METHOD: volunteers, eighteen-year-old and older assisted at the National Center for Social Re-education (CENARESO) during 2006-2007, who had consumed coca paste over the past 6 months previous to the interview and had never injected drugs, were selected. A structured questionnaire was used and blood was drawn to test HIV, HBV, HCV and syphilis. A sub-sample of thorax X-rays was analyzed. RESULTS: more than half of the 146 volunteers had smoked coca paste several times a week. The use of other drugs was frequently associated: sniffed cocaine 64%, cannabis 80,8%, and tranquilizers 44,5. Oral lesions and lost of weight were referred as health problems stemming from coca paste use. Out of the 146 volunteers, 4.3% resulted HIV-positive. Prevalences of infection for syphilis, HBV, and HCV were 2,7%, 5,5% and 5,5%, respectively. 16% was co-infected with one or more infectious agents.
