Is sneezing a side effect of giving up smoking?

Yes, sneezing can be a temporary side effect of quitting smoking. When you stop smoking, the cilia (tiny hairs) in your nose and throat start to grow back which helps to sweep away mucus and irritants more effectively. This increased activity, coupled with the body’s attempts to expel nicotine toxins, might contribute to an increase in sneezing during the initial nicotine withdrawal period for some individuals.
