The main objectives of this paper were to estimate the consumption patterns of tobacco use among King Saud University (KSU) undergraduate students; and investigate different risk factors which may contribute to tobacco use among female students. A representative sample (n=7550) of the total KSU undergraduate student population of 69,498 (males and females) was selected, stratified according to college and gender. A modified version of the WHO/CDC Global Youth Tobacco Survey (GYTS) questionnaire was used for data collection. Overall smoking prevalence among KSU students was estimated at 14.5%, prevalence among male students (32.7%), and females (5.9%). Independent risk factors for smoking among males were found to be: age, father's smoking habits, and "friends' smoking habits"; while among females were: sister's smoking habits and "friends' smoking habits." The findings of this study re-emphasize the significance of peer pressure on smoking among university students of both sexes; influence of family members, usually of same sex. We need to foster gender-sensitive tobacco prevention intervention programs, to prevent youngsters of both sexes from taking up such habit. We also need to raise awareness of girls and young women, of the consequences of smoking in general, water-pipe in specific, on their own health, that of their spouses, families, and off-springs, many of whom could develop chronic respiratory disorders, as passive smokers in the beginning/potential smokers themselves, later on. All such efforts should be backed and supported by strong governmental commitment, to ensure success of their implementation accordingly.

Tobacco use is increasing among young people, especially in Gulf nations such as Saudi Arabia. The objectives of this study were to estimate the prevalence and behavioural patterns of tobacco use among undergraduate students at King Saud University, Riyadh, Saudi Arabia during the academic year 2008/09 and investigate factors that influenced their tobacco use. A cross-sectional study was done of a representative sample (n = 6793) of the undergraduate student population using a modified version of the global youth tobacco survey questionnaire. The prevalence of smoking was 14.5% among students, 22.2% and 2.2% among fathers and mothers and 43.1% and 14.8% for male and female siblings; 15.0% reported all or most of their friends smoked. The most important independent predictors of smoking were: friends' smoking (some: OR = 6.7 and all: OR = 54.9), sister's smoking (OR = 2.2), mother's smoking (OR = 2.1), single status (OR = 1.7) and age (OR = 1.18).

Psychoactive drug use is generally low in Iraq, tobacco being highest at an estimated 23.2%. Iraqi women report significantly less substance use than Iraqi men, which may be related to cultural gender norms. Discrepancy between self-report and 'knowing someone who uses a substance' suggests under-reporting in this population.
