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.
After you quit smoking, a lot of good things happen to your body very quickly. Within just 20 minutes, your heart rate and blood pressure go down. Within 12 hours, the carbon monoxide levels in your body go back to normal. And within a couple of weeks, your circulation improves and youâre not coughing or wheezing as often. But some pretty unpleasant things happen right away, too. The symptoms of nicotine withdrawal include: 1  Anxiety. 2  Irritability. 3  Headache.
