Results: 92% of students denied the abuse of drugs, and 10% believed that drugs had a positive effect on people’s mood. 27% believed that curiosity is a factor that causes the attraction to drugs. 4% of students reported  going to places with a high risk considering drugs of abuse. Students discussed drugs more with their friends, family, and teachers in order 9% do not introduce their friends to their parents. Pearson correlation coefficient test showed significant and positive correlation between age (p<0.004), number of family members (p<0.05), and birth order (p<0.05) with total attitude score and pro-social behaviors.
