Why do you faint after a few days without smoking?

This situation is commonly known as drinking and smoking. Drunk smoking is caused by nicotine poisoning. Novices or people who can't smoke smoke too much at a time. Nicotine and carbon monoxide dissolved in the blood will cause toxic reactions to smokers, commonly known as drunk smoking. Its manifestations are dizziness, nausea, strong vomiting, sphincter relaxation, general weakness and incontinence. It usually lasts for more than ten minutes, and in severe cases, it will be life-threatening. Smokers are used to the stimulation of nicotine, so there will be no poisoning symptoms. However, if you quit smoking for a long time and then smoke again, you will also feel slightly dizzy.
