          The popularity of e-cigarettes is increasing rapidly worldwide and advertisements for such products are becoming ubiquitous in the media. Health concerns and smoking cessation are the most commonly reported reasons for traditional tobacco smokers to shift to e-cigarettes. As a result, the global market for e-cigarettes is on the rise. However, they are still a potential cause for many diseases.


          This is a cross-sectional study carried out at Qassim University in Buraydah, Saudi Arabia. A prevalidated questionnaire was distributed to medical students in April 2018 to evaluate the experience, knowledge, and awareness of e-cigarettes among the participants.


          About one in ten students confirmed having smoked an e-cigarette. There was no significant relationship between e-cigarette users and demographic factors, such as gender, academic level, or age. However, the study showed a significant association between e-cigarette smoking and having an e-cigarette smoker among family members or friends. Most students 71.9% were not sure whether e-cigarettes were approved by the Food and Drug Administration (FDA) for smoking cessation. Only 23.3% of those surveyed believed that e-cigarettes can help in smoking cessation, whereas only 11% said that they would recommend it for a patient. On the contrary, 49.6% agreed that e-cigarettes are addictive. In response to another question, 92% reported receiving no education in medical school about e-cigarettes.


          Our study showed that medical students lacked knowledge about e-cigarettes. Therefore, more studies are needed to raise awareness about e-cigarettes, especially since the habit of using e-cigarettes is invading our society.

            Tobacco Smoking and Lung Cancer: Perception-changing facts.

            Tobacco smoking remains the most established cause of lung carcinogenesis and other disease processes. Over the last 50 years, tobacco refinement and the introduction of filters have brought a change in histology, and now adenocarcinoma has become the most prevalent subtype. Over the last decade, smoking also has emerged as a strong prognostic and predictive patient characteristic along with other variables. This article briefly reviews scientific facts about tobacco, and the process and molecular pathways involved in lung carcinogenesis in smokers and never-smokers. The evidence from randomised trials about tobacco smoking's impact on lung cancer outcomes is also reviewed.

              Cigarette Smoking and Electronic Cigarettes Use: A Meta-Analysis

              Increasing evidence indicates that cigarette smoking is a strong predictor of electronic cigarettes (e-cigarettes) use, particularly in adolescents, yet the effects has not be systematically reviewed and quantified. Relevant studies were retrieved by searching three databases up to June 2015. The meta-analysis results were presented as pooled odds ratios (ORs) with 95% confidence intervals (CIs) calculated by a random-effects model. Current smokers were more likely to use e-cigarette currently (OR: 14.89, 95% CI: 7.70–28.78) and the probability was greater in adolescents than in adults (39.13 vs. 7.51). The probability of ever e-cigarettes use was significantly increased in smokers (OR: 14.67, 95% CI: 11.04–19.49). Compared with ever smokers and adults, the probabilities were much greater in current smokers (16.10 vs. 9.47) and adolescents (15.19 vs. 14.30), respectively. Cigarette smoking increases the probability of e-cigarettes use, especially in current smokers and adolescents.
