How long it takes nicotine to leave body after you quit smoking? -
I smoked for 35 years,up to 2 packs aday when I quit
Nicotine metabolizes very quickly in the body, with a half-life of about two hours. Nicotine metabolites are longer-lived. The most stable nicotine metabolite is cotinin, which has a half-life of about 16 hours.

Cotinine disappears in 2-4 days.

Don-t confuse the longevity of nicotine and its metabolites in your body with how long the effects of smoking linger.
I heard some peopel say and much as 3 hours.
All the studies I read about quiting smoking say that the tar and nicotine tak up to 10 years to completely leave the body. You start noticing a change after a few days, and after about two weeks you start to notice a big difference.
believe it or not, it only take a week for it to be out of your system completely. the 3rd and 4th day are the hardest, because thats when your body starts to react from not having a daily dosage of nicotine in your system. you will always have a hard time iwith it on and off for months afterwards, but its a mental craving, nothing physical. if you can make it through the first 4 days you have it beat. after that you will feel it get so much easier. (just try to keep your stress level down though) thats the main cause for people to go back to smoking. fight the urge by excersicing or drinking alot of water and chewing gum.
I-ve heard 3-4 days. I wish you luck, hopefully you have the willpower to quit. My wife claims to -try- then forgets or just tries to hide the fact she doesn-t have the strength to quit.
It takes 6 months for your lungs to be entirely free of tar and nicotine.
i believe its 72 hours and after that its all in your head so if you can convince your mind you don-t need it anymore your home free....as with so many things in life its all in your head....good luck though cigs. are a nasty habit.
I quit smoking over five years ago and focused on getting fit. As I recall back then, I was told nicotine takes three days to leave your bloodstream, but it takes about one month to break the habit of holding a cigarette in your mouth or hands. It then takes 9 months for your lungs to become free of tar and about five years to get to the point where your body feels as if you had never smoked at all.
If I recall, It takes about 48 hours for nicotine to exit the system, from there on out, it-s all in your head
