[Health promotion and education in secondary schools: knowledge on drugs abuse]

To prevent behaviours at risk for the use of substances that induce dependence, some meetings have been planned with children primary school, age in which it's still possible to prevent the contact with drugs and children are more receptive. Two questionnaires have been given to the students, a pre-test before the interview, to value their knowledge about drugs, and a re-test after the interview, to value if the knowledge objectives suggested had been reached. After meeting the students seemed to be more informed because there were statistically significative differences between the percentages of the correct answers of the pre-test and the re-test.
