Percentage of children who have used cannabis (hashish or marijuana) once or more over their lifetime (16 yr)

Hlutfall barna sem hafa notað kannabis (hass eða marijúana) einu sinni eða oftar yfir ævina (10. bekkur)

The percentage of children who have used cannabis once or more over their lifetime shall be calculated as the total number of children who answer "1-2 times", "3-5 times", "6-9 times", "10-29 times", "20-39 times" or "40 times or more" to the questions "How often (if at all) have you used the following substances over your lifetime? - Hashish" and "How often (if at all) have you used the following substances over your lifetime? - Marijuana" (numerator) divided by the total number of children who answer the questions (denominator). The result shall then be multiplied by 100 and expressed as a percentage. Information gathered from a report by ICSRA that conducted a public health survey of children aged 13 to 16. In the report the percentage of individuals in 10th grade that have used hashish or marijuana once or more over their lifetime. Response options were "never", "1-2 times", "3-5 times", "6-9 times", "10-29 times", "20-39 times", "40 times or more"

Hlutfall barna sem hafa notað kannabis einu sinni eða oftar yfir ævina skal reiknað sem heildarfjöldi barna sem svara "1-2 sinnum", "3-5 sinnum", "6-9 sinnum", "10-19 sinnum", "20-39 sinnum" og "40 sinnum eða oftar" spurningunni "Hve oft (ef nokkru sinni) hefur þú notað eftirtalin efni um ævina? - Hass" eða "Hve oft (ef nokkru sinni) hefur þú notað eftirtalin efni um ævina? - Maríjúana" (teljari) deilt með heildarfjölda barna sem svara spurningunum (nefnari). Niðurstaðan skal margfölduð með 100 og sett fram sem prósenta. Í lýðheilsukönnun R&G má finna hlutfallsfjölda þeirra í 10. bekk sem svöruðu því játandi að hafa hafa notað hass eða marijúana einu sinni eða oftar um ævina. Svarmöguleikar voru "aldrei", "1-2 sinnum", "3-5 sinnum", "6-9 sinnum", "10-19 sinnum", "20-39 sinnum", "40 sinnum eða oftar".
