Recreational use of benzydamine as a hallucinogen among street youth in Brazil.

OBJECTIVE To describe the recreational use of benzydamine, an anti-inflammatory drug, among street youth in Brazil. METHOD DESIGN a descriptive, cross sectional survey. SETTING 93 welfare services for the street youth in 27 Brazilian capitals. PARTICIPANTS 2807 street youth, 10 to 18 years old. MAIN OUTCOME MEASURES demographic characteristics, drug use pattern (lifetime use, use in the past 30 days, frequency, and characteristics of use in the past month) and effects of benzydamine through the use of a questionnaire. RESULTS 78 reported lifetime recreational benzydamine use (67 cases identified only in three capitals). Among the 30 respondents reporting drug use in the last month (the month preceding the survey), 66.7% (n = 20) used the drug on 4 or more days (in the month preceding the survey). The most frequently (50%) pleasure effects reported were hallucination and nonspecific sensory changes described as 'trips'. Unwanted effects were reported by 75% of respondents, they were especially nausea and vomiting (21.4%). In the majority of the cases, drug was obtained from drugstores without a medical prescription. CONCLUSION This study identifies the recreational use of benzydamine among street youth, mainly in the Northeast of Brazil, and also indicates the need for special controls on the dispensation of this substance.
