After smoking for a while, the pathways in a smoker's brain change so that the nerve cells need nicotine to function normally. For heavy smokers, if their brain is not topped up with nicotine they experience what I call 'nicotine hunger'. This adds to the situational cravings and can occur at any time.
People who use tobacco products get used to having a certain level of nicotine in their body. After you quit, cravings develop when your body wants nicotine. This may occur long after your body is no longer addicted to nicotine.
Cravings for nicotine can start 30 minutes after your last cigarette. Individual cravings usually pass in 3 to 5 minutes. You may get the most cravings 2 to 3 days after you stop smoking. You should stop getting cravings 4 to 6 weeks after you stop smoking.
When you quit smoking, you cut off the supply of nicotine to the brain receptors, causing them to adjust, reducing the amounts of nicotine in your body. When your brain notices the lack of nicotine, it sends signals that it wants more. This is nicotine withdrawal, which causes your cravings.
Cravings are still constant and someone who was an average smoker will experience at least 4-6 episodes per day.
Nicotine withdrawal symptoms set in between 4 and 24 hours after a person last vaped. The symptoms peak around day three of abstinence and then gradually subside over the following three to four weeks.
Types of Cigarette Cravings

Week 3 After Quitting Smoking
