Some patients can get over nicotine cravings within a few days, others it takes weeks and some never get over the cravings. It all depends on the individual and how their body reacts to stopping.

- After 20 minutes the body starts changing.
- After 12 hours the blood level drops and becomes normal.
- After 48 hours taste and smell start improving.
- After 72 hours the bronchial tubes start relaxing.
- After 12 weeks circulation starts to improve.
- After three months the risk for a heart attack drops.
- After 9 months coughing and sinus issues decrease.
- After 15 years coronary heart diseases decrease.

There are medications, patches and programs to help with patients that are trying to stop nicotine cravings. While it might not happen over night with the majority of people it can still be done.
