nicotine dependence can appear within days to weeks of the onset of occasional use, often before the onset of daily smoking. The existence of three groups of individuals—rapid onset, slower onset, and resistant—distinguishable from one another by their susceptibility to nicotine dependence, is postulated.
Try nicotine replacement products or ask your doctor about other medications. Remind yourself that cravings will pass. Avoid situations and activities that you used to associate with using tobacco products. As a substitute for smoking, try chewing on carrots, pickles, apples, celery, sugarless gum, or hard candy.
Usually if you smoke more than 10 cigarettes a day, or have a cigarette in the first half hour after waking up, you have a nicotine addiction that is significant enough to give you some real trouble when quitting.
Generally, nicotine will leaves your blood within 1 to 3 days after you stop using tobacco, and cotinine will be gone after 1 to 10 days. Neither nicotine nor cotinine will be detectable in your urine after 3 to 4 days of stopping tobacco products.
Frankly, caffeine has no real health risks - and it's no nearly as addictive as nicotine. Whether in the form of electronic cigarettes, tobacco cigarettes, or chewing tobacco - nicotine is a harmful substance physically and mentally.
Nicotine is absorbed into your bloodstream and goes to your adrenal glands just above your kidneys. The glands release adrenaline which increases your blood pressure, breathing, and heart rate. Adrenaline also gives you a lot of good feelings all at once.
Physical cravings: Your body's reaction to nicotine withdrawal can be felt physically. 2 Physical cravings are usually experienced as a tightness in the throat or belly, accompanied by feelings of tension or anxiety. Psychological cravings: These are triggered by everyday events.
Nicotine is a toxic substance. It raises your blood pressure and spikes your adrenaline, which increases your heart rate and the likelihood of having a heart attack.
Withdrawal occurs as a result of dependence, when the body becomes used to having the drug in the system. Being without nicotine for too long can cause a regular user to experience irritability, craving, depression, anxiety, cognitive and attention deficits, sleep disturbances, and increased appetite.
The withdrawal timeline is also different for everyone, but according to a 2015 study, symptoms like these set in between 4 and 24 hours after the last use, peak on day 3, and typically subside during the following 3-4 weeks.
Most people should expect to experience some of the following vaping withdrawal symptoms such as headaches, mood swings, anxiety or irritability, to start within about 24 hours of the last vape.

Are e-cigarettes less harmful than regular cigarettes? Yes—but that doesn't mean e-cigarettes are safe. E-cigarette aerosol generally contains fewer toxic chemicals than the deadly mix of 7,000 chemicals in smoke from regular cigarettes. However, e-cigarette aerosol is not harmless.
Compared to smoking cigarettes, which kills 6 million people around the world every year, nicotine on its own is less harmful.
While you're smoking: Nicotine disrupts sleep – and smoking can also raise the risk of developing sleep conditions, such as sleep apnea. But since nicotine is a stimulant, smoking can mask your exhaustion. After all, if you're feeling sleepy, a hit of nicotine can wake you up and make you feel alert the next day.
Nicotine acts as both a stimulant and a depressant to the central nervous system. Nicotine first causes a release of the hormone epinephrine, which further stimulates the nervous system and is responsible for part of the "kick" from nicotine-the drug-induced feelings of pleasure and, over time, addiction.
Smoking, anxiety and mood
It's a common belief that smoking helps you relax. But smoking actually increases anxiety and tension. Smokers are also more likely than non-smokers to develop depression over time.
Blood testing
There are several tests that can be used to measure cotinine levels. Blood testing is very accurate and can detect both nicotine and cotinine. It's also the most expensive and invasive testing method, so it's less frequently used than the other methods.
Nicotine shows up in blood tests, as do its metabolites, including cotinine and anabasine . Nicotine itself may be present in the blood for only 48 hours, while cotinine may be detectable for up to three weeks. After blood is drawn in a lab, results can take from two to 10 days.
