The NHANES study determined that smoking can be linked to greater risk of olfactory alteration. [21]  Research has identified squamous metaplasia and change in the morphology of the olfactory receptor neurons in smokers, as well as a higher level of apoptosis of these neurons in smokers than in controls. In addition, there is evidence that the volume of the olfactory bulb is reduced in smokers. [22]
