In brief: Less than a day
The nicotine will be gone inside of a day and the tars will be cleaned up by the body's defenses in even less time than that.
Don't go for a second cigarette!

In brief: Varies
Carbon monoxide will be gone after 4 months when all of the red blood cells it covered are replaced by new ones.
Nicotine will be gone within a few hours. Heavy metals with stay with you forever until you get chelation therapy to remove them--but for one cigarrette i would not bother. Other toxins as in pesticides may take other variable times to be expelled ; www.Medacpc.Com.
