Cannabis smoking among school-age (11, 13, 15 y. o.) children.
Age groups are formed on the basis of forms 5, 7 and 9. The majority of students of these forms are 11...12, 13...14 or 15...16 years old. However, the research must also include the students who are repeating the year. As a prerequisite, 90% of the students must be of ±6 months the mean age of their age group, the remaining 10% must not be over the mean age of more than 12 months. The specification into age groups of 11, 13 and 15 years is in a way conditional because the cleaned files include also 12, 14 and 16 year old students in a certain amount.
Unit: percent
Disaggregated by: academic year, age, cannabis smoking, gender
Note: 2005/2006 academic year data is weighted. 2009/2010 academic year data is unweighted, but is representative.
