Nicotine Detox-How long should it last. As was mentioned at the beginning of this article, the intensity of the physical cravings will normally start waning after 3 days. A period of 2 weeks should be a sufficient time period for your body to have readjusted itself to living without nicotine.
The first effects of nicotine withdrawal will be felt within 6 hours of having your last cigarette. However the peak time for these nicotine withdrawal side effects will be the second and third day post-smoking cessation. From then on depending on the factors I mentioned earlier on, nicotine withdrawal will begin to diminish over a 2 â 3 week period. So in effect, you could say on average that nicotine withdrawal will last about 3 weeks. However, it could be shorter in some people and in heavy smokers who have smoked for 20 years or longer, the nicotine withdrawal could last for up to 2 months. So you now have a rough idea of how long nicotine withdrawal does last. Most people will fall in between those withdrawal timelines.
