How Long Does It Take For Nicotine Cravings To Stop
I gave up smoking in 1970 but my feet are still addicted. They want to go into any tobacco store I pass. I still have to be very firm with them and order them to walk in the opposite direction.
But I did quit. With less damage than if I had continued. ...Read more

How long does it take for nicotine to leave your body (urine and blood stream) after you've stop smoking?
It varies: Nicotine metabolism is complex. Most nicotine is metabolized in the body to co-nicotine, and this is what is tested for. Nictotine is 1/2 gone after 2 hours, co-nicotine about 20. It takes about 5 1/2 lives for a drug to be "97% gone". 10 half lives for 99.9% another source says a urine test can be positive 7 to 20 days after smoking. ...Read more

Better question:: The more pragmatic question is whether you will benefit from ongoing nicotine replacement. About a third of patients who are tobacco dependent will live longer if they are maintained on nicotine replacement. Serum cotinine levels are the most accurate predictor but clinically if one has or had a history of craving for a cigarette within the first 1/2 hour of awakening - consider replacement. ...Read more
Hey doctor, so I am a smoker I quit for 1 month but I got back smoking 10-20 cigs a day. How long does it take for nicotine or cotine not to show.
Nicotine is rapidly: Converted to cotinine & is detectable in blood for 1-3 days. Cotinine is detectable in urine for up to 10 days. Nicotine/cotinine may stays in hair for 3+ months but the test is expensive & seldom done. It's easy to "cheat" on a urine drug test for tobacco. But, in the long run, the only person you're cheating by continuing to smoke is you! You cheat yourself out of a long, healthy life.... ...Read more
How long does it take for nicotine from chewing tobacco to be completely flushed from your system so that it cannot be detected? I need to take a nicotine test for a job and I need to know how far in advance I need to quit the stuff.
2-3 days: Nicotine is a short-acting drug, and is usually metabolized into cotinine which lasts for up to 72 hours. If you give it one week, your test should be negative. However, you should stay stopped - chewing tobacco damages your teeth, can cause oral cancer, makes your breath stink, and is a thoroughly nasty habit. Get some help if you need it - most ballplayers have stopped, usually with gum. ...Read more
2-3 days: nicotine is a very short-acting drug, and its main metabolite cotinine is too. After a single cigarette, levels will usually only be detectable for 24 hours, and most regular smokers will be detectable for 3 days or so. Depends on how it is tested, with oral swabs picking it up for longer, blood tests have a shorter window, urine is in the middle. Hair tests can go back months. How about stopping? ...Read more
Each cigarette: Contains about 1 mg of nicotine, and its half-life is about 2 hrs. It also is multicompartmental, meaning it can be "accumulated" in adipose tissue, detoxified to cotinine by cytochrome p-450 enzymes, so eliminaion entrely can be complicated by the direct half life, and then the leeching from the fat cells. It's complicated! ...Read more
24-48 hours: nicotine is usually not what is tested for, but its main metabolite cotinine. Nicotine is extremely short-acting - that is why people smoke 20 cigarettes a day (or about one an hour when awake). Cotinine lasts longer, and can be found in blood for 1-2 days and in urine for 2-3 days. Oral swabs can detect it potentially for slightly longer. ...Read more

After 20 yrs of smoking I am trying to quit. I am on day 4 without a cigarette. How long does it take for all the nicotine to be gone?
It's hard to be sure: Nicotine has relatively short half-life (30-min-120min) because it is broken-down by liver via oxidation process and thus disappears rather quickly--hence people feel need to smoke often. Chronic smokers will have nicotine in body for longer, but I would guess after 1 wk, there isn't much left to bother you. Traces of that can still be detected up to 2 months later. Congrats on quiting. Good luck. ...Read more

Doctors, what are the effects of nicotine withdrawal and how long does it take for the effects to happen?
Many effects and: A short time after last use. Nicotine is a short-acting drug, which is why people who smoke average 1-3 cigarettes per hour while awake (as opposed to heroin 3-4X/day). Withdrawal consists of anxiety, craving for tobacco, muscle tenseness, insomnia and irritability. It occurs within 4-7 hours after last dose, which is why very dependent smokers need a cigarette as soon as they wake up. ...Read more
I need to have back surgery I am down to 10 smokes a day how long will it take for nicotine to not show up and what's the best way to totally quit thos?
Great job: Great job and keep up the good work! Non smokers do tremendously better with elective spinal surgery than smokers. It is generally thought that nicotine stays in your system about 4-6 weeks after your last cigarette. Non nicotine meds would be better than medications containing nicotine to help quit; Chantix is just one example. Don't hesitate to seek help as well. ...Read more

Stop for 2 weeks: To be safe, you might want to stop smoking for a couple weeks. They are testing for cotinine which is a metabolite of nicotine. It has a long half life up to 40 hours. This tests shows positive for both active smokers and those who have quit but are using nicotine patch, gum, etc. Another test is used to identify active smokers. It is called anabasine and found in tobacco products. Try 2 wks off. ...Read more
After a cigarette:
The average smoker with 1 MG of nicotine, after an hour or two, a trace is still left. The nicotine is metabolized in the liver and there is nothing to interfere with the breaking down of the substance.
The metabolite of nicotine is eliminated in the kidneys, which can be detectable in the urine for at least a week in the typical smoker. Insurance companies may test for the metabolite. ...Read more
It can go on for: Some time, at least several weeks if not a month or more. If the cravings are severe, getting in the way of your life, or making it likely you will relapse to tobacco, I would strongly consider nicotine replacement therapy, either with patches in tapering doses (21 mg to 14 mg to 7 mg every 1-2 weeks), or just use gum/lozenges when they are bad. Congrats on quitting, and try to stay quit. ...Read more
