Effect of smoking on active male smokers across various age groups

The most common form of smoking in the world is cigarette smoking, which is one of the leading causes of lung cancer, blood pressure, emphysema, bronchitis, heart attack etc... In the present study, Fourier-transform infrared spectroscopy was used for analysis of saliva sample for the detection of markers for smokers. The analysis included 7 individuals. The samples were classified as 2 samples from smokers of group 10-25, 2 samples from smokers of group 25-40, 1 sample from smokers of group 40-60 and 2 samples from smokers of group 60 & above. Several interesting peaks have been identified as markers for smokers from saliva sample. Many peaks were significantly altered in absorption level of different age groups. The peaks at 754 cm, 1644 cm, 2136 cm, 3408 cm were altered differently in different age groups as compared to non-smokers. Our study indicates that a stable marker was possible for active smokers by analysing the spectral graph obtained from the FTIR technique. These parameters could be used for developing a spectral method of detection of active smokers along with predicting their duration of smoking by studying the effect of smoking in the different age groups.
