Smoking is a habit, usually easy to pick up but extremely difficult to let go. Several youths in their prime find smoking a “cool” indulgence and in most cases do not draw any direct pleasure from it. With time though, they become addicted to the nicotine and in the process grow as older smoking. With it come the health risks such as cancer, lung disease, stroke, heart attack, gum disease among others. Other undesirable outcomes have long been associated with smoking. In retrospect, it is of vital importance that individuals should quit smoking. It begins by the individual admitting that the practice is dangerous, health-wise and therefore must quit. The next step is draw a plan on when and how to stop smoking. The individual should develop activities that would replace time spent during smoking. Either, a change of character will be paramount for the individual to do away with things that remind them of the smoky past. Finally, quitters who need additional pharmaceutical therapy may seek such therapy with the assistance of qualified physicians.
As you can imagine, cigarette smoke contains many impurities that are inhaled in great numbers directly into the lung. For this reason, the alveolar spaces of the smoker contain numerous scavenger cells (macrophages) that are filled with engulfed (phagocytized) particles of impurities and debris, as illustrated in Picture of scavenger cells in a smoker's alveolus Under the microscope, with this high magnification, you can actually see the black and brown engulfed particles in the alveolar scavenger cells. Indeed, smoker's lung may have so much of this particulate material that the lung looks gray-black to the naked eye. Most of the time, you don't need a microscope to tell if someone is or was a heavy smoker. A naked eye examination of a smoker's lung will usually reveal an enlarged gray-black lung with enlarged air spaces (the emphysema, as you saw in Figure 4 and will see again in Figure 8).
