Background: The present study was designed to determine the risk factors that lead to bango abuse among secondary school student and drivers in Assiut province.
Subjects and Method: urine samples were taken from 1000 volunteers after filling a questionnaire, 500 students from different secondary schools and 500 drivers in Assiut province. The risk factors that lead to bango abuse among drivers and students were determined through the questionnaire. Screenings of the samples were done by using Thin Layer Chromatography (TLC) and then positive samples confirmed by high performance liquid chromatography (HPLC).
Results: prevalence of bango abuse was 12% in drivers of the studied group. Bango abuse concentrated in age group of 21- 31Y/O by 51.7% and in those driving microbus, van and half van by 30%, 28.3% and 23.3% respectively. Abuse was more among cigarette and shisha smokers by 83.3% and 100% respectively. Also it was found that bango abuse is more prevalent in cases with 5 - 15Y work experience (58.3%of cases). In students, it was found that bango abuse was prevalent in 11.6%, concentrated in male students by 100%, and in those with daily fund more than one pound (44.8%). The abused students tend to be more aggressive toward their friends and their family members (by 65.5% and 96.6% respectively).
Conclusion: bango abuse leads to deterioration of the academic achievement, and may be associated with antisocial and violent behavior, which may be a leading cause to develop crime.
