The new coronavirus is not afraid of nicotine, which is mainly found in cigarettes, so some people have the sudden idea to kill the coronavirus by smoking, which is an impossible situation. Although a large amount of nicotine can kill the little white rabbits and other small life, but there is no role in killing germs, so nicotine will not kill the coronavirus, while smoking the temperature in the airway can not reach more than 56 ℃, so by smoking to achieve the role of high temperature to kill the coronavirus is impossible and unrealistic. On the contrary, long-term smoking will cause chronic inflammatory stimulation of the respiratory tract, resulting in the destruction of the barrier function of the respiratory tract, and its ability to resist germs decreases, so that coronaviruses are more likely to invade the body and cause the body to develop.
