A cross-sectional study on a pool of undergraduate smokers and nonsmokers () was randomly selected from Notre Dame University, Lebanon. The study design is based on a questionnaire about the students’ smoking record exposure, cotinine saliva levels, and ventilatory lung function parameters. Despite the nonsmoking policies that have been recently established by universities, diffused smoking stations in proximity to classes and offices still exist, at least in the MENA region. Such an environment still imposes a remarkable effect on certain lung health parameters of nonsmokers exhibiting similar exhaled air per second (FEV1) to smokers with a value = 0.558 and normal flow of air (TV) with a value = 0.153. However, the maximum amount of air held in the lungs remained different with respect to sex and smoking status. These results imply a poor performance of nonsmokers mimicking partially the lung health parameters of smokers. It remains a pressing issue to increase awareness concerning the debilitating effects of secondhand smoking.
