Lu Lin footballer of Peking University Sixth Hospital said that the essence of tobacco addiction and dependence is nicotine dependence, which is a chronic and highly recurrent disease.
However, e-cigarettes are not recommended for the following reasons:
E-cigarette is a new product in recent years after all. The acceptance population and market are still uncertain, and the supervision and safety of e-cigarettes are still blank. Whether it is healthier than real cigarettes or has unknown hazards after long-term use is unknown, so the state does not support the purchase of e-cigarettes.
So I suggest giving up smoking.
Smoking cessation methods:
It is difficult and important to quit smoking in the early stage. Here are seven ways to quit smoking in the first five days:
(1) Drink 6- 1.8 glasses of water (about one liter of boiled water) between meals to promote nicotine excretion.
(2) Take a warm bath every day. If you can't help smoking, you can drench yourself immediately.
(3) Quit smoking for five days, have a full rest and live a regular life.
(4) Take an outdoor walk after dinner and take a deep breath 15-30 minutes.
(5) Drink milk, fresh fruit juice and cereal drinks instead of stimulating drinks.
(6) Try to avoid eating poultry food, fried food, candy and dessert.
(7) you can eat a variety of vitamin B groups, which can calm your nerves and eliminate nicotine.
After the first five days, you can keep quitting smoking successfully in the following ways:
(1) Brush your teeth or rinse your mouth after meals, wear clean clothes and don't smoke.
(2) Replace the habit of smoking with a pen or pencil.
(3) Stay in the library or other places where smoking is not allowed most of the time.
(4) Avoid going to bars and attending banquets, and avoid being with heavy smokers.
(5) Buy yourself a gift with the money saved by not smoking.
(6) Prepare to quit the habit of wanting to smoke within 2-3 weeks.

Effect of nicotine
I. Pharmacology
Nicotine acts on nicotinic acetylcholine receptors, especially autonomic receptor ((α 1)2(β4)3) and central nerve receptor ((α4)2(β2)3), the former is located in the medulla of accessory kidney and the latter is located in the central nervous system.
At low concentrations, nicotine can increase the activity of these receptors, and nicotine also has a small direct impact on other neurotransmitters. High concentration inhibition.
Second, the central nervous system.
Nicotine can combine with nicotine acetylcholine receptor, increase the amount of neurotransmitters, and increase dopamine in the brain. Nicotine actually creates a sense of emptiness in the brain. After increasing the concentration by smoking, it relieves the emptiness caused by the rapid metabolism of nicotine, gives people the wrong illusion that smoking can give people confidence and relaxation, and may eventually become addicted to smoking.
The smoke produced by tobacco burning contains monoamine oxidase inhibitors, which decompose monoamine neurotransmitters, dopamine, norepinephrine and serotonin.
Nicotine can positively regulate α4β2 nicotinic acetylcholine receptors in cerebellum and brain stem of long-term smokers.
Third, the peripheral nervous system
Nicotine can stimulate sympathetic nerve, which can affect the medulla of accessory kidney and release adrenaline by stimulating visceral nerve. The parasympathetic preganglionic fibers release acetylcholine, which acts on nicotinic acetylcholine receptors and releases adrenaline and norepinephrine into the blood.
Fourthly, the medulla of accessory kidney
When nicotine binds to nicotine receptors in adrenal medulla, it will increase the content of adrenaline in blood.
Through the results with the receptor, nicotine depolarizes the cells, and calcium ions flow in through calcium channels, prompting nerve cells to release adrenaline and norepinephrine into the blood by exocytosis, and the adrenaline in the blood increases, leading to faster heart beating, higher blood pressure and faster breathing, just like hyperglycemia.
Cotinine is a by-product of nicotine metabolism, which can remain in the blood for 48 hours and can be used as a substance to detect whether a person smokes.
