In order to evaluate the proportion of the provided education for young people who probably consumed drug, an epidemiological investigation was carried out in 3141 pupils; out these 2135 were boys and 1006 girls. Among the interviewed pupils, 316 (10.06%) admitted having already consumed at least once of drug. Among them, 258 boys (either 12,08%) already consumed drug against 58 girls (or 5,77%). This study evaluated the proportion of the consumers by age bracket. Thus, three age brackets were considered to range from [9-13 years, [13 - 19 years, and [19 - 22 years]. The results indicate that 578 pupils from 9 years old and less than 13 years, 27 (that is to say 4,67%) consume these substances. Among the 13 years old pupils to less than 19 years, 173 on a total of 1634 individuals consume drug (either 10,59%) and 12,49% of the pupils from 19 to 22 years are also consumers. The consumption of drug was also evaluated at its subjects surveyed by level of study. Thus, the distinction is made between the first cycle and the second cycle. On this subject, one notes that on 1575 subjects questioned with the first cycle, 150 (either 9,52%) admitted having consumed drug against 166 out of 1566 pupils questioned (or 10,60%) with the second cycle. Our studies have shown that age and level of education would influence drug use.
