Problem/Objective: Study knowledge, behaviors, attitudes towards smoking, smoking restrictions, quitting and health related issues among medical and none medical.

Methods: Descriptive cross-sectional study on cohort of 400 employees of NCI medical 46.2% and non 53.8% using anonymous self-administered questionnaire... Nicotine dependence was estimated for cigarettes smokers using Heaviness of Smoking Index Waterpipe Smoking Index to estimate dependency. Logistic regression odds ratio and its confidence intervals were calculated to estimate risk.

Results: Medical group was significantly more knowledgeable (p<0.05) than, non, about smoking-related health hazards; no significant differences between them in their smoking behaviors, and the two groups did not differ regarding their attitudes toward smoking restrictions at the workplace. Non smokers in non-medical were significantly (p=0.041) more active than their medical counterparts in their attitude towards smoking colleague, by asking him to put out the cigarette or to smoke in another place. The non-medical had significant elevation (p=0.002) in their overall health problems related to smoking than their medical counterparts., peer pressure (55.2%) was the most common cause of starting cigarette smoking, and stress (38%). About 88% of them tried to quit before, 61% wanted to quit improving their health. Only 21% succeeded, 38% of them achieved cessation after more than three attempts. Water pipe smoker preferred to smoke at café.

Conclusions: Medical personnel in study, despite increased knowledge of health-related negative consequences of smoking, were not more likely than their non-medical to avoid or quit smoking, and they were less likely to ask smokers at workplace to put out cigarette or smoke elsewhere.
