I smoked a cigarette for the first time today. How long will it take for iit to get out of my system?

See below. The nicotine will be gone in six to twelve hours. Cotinine levels will be around longer.
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!
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.
