Hazard Introduction

Effects of Tobacco on the Brain: Nicotine spreads throughout the body through the lung and oral mucosa. After entering the brain, nicotine can mimic the action of acetylcholine, a neurotransmitter, and bind to many nicotine receptors on the surface of neurons. Nicotine has a stimulating effect on the central nervous system, particularly in the "reward circuit". It can release more dopamine by activating relevant nerves. The Hamming and norepinephrine contained in tobacco can maintain high concentrations of dopamine, serotonin, and noradrenaline in neural synapses through continuous enzymatic activity. As the effects of dopamine, serotonin, and norepinephrine are strengthened, a person's level of alertness becomes higher, attention becomes more focused, and thus they are better able to alleviate anxiety and endure hunger. Tobacco can cause nausea, dizziness, and headaches

Tolerance and dependence: Frequent smoking can keep nicotine levels in the brain consistently high. Neurogen receptors are becoming increasingly insensitive to nicotine, and the stimulating effect on dopamine release is also weakening. The original amount of smoke can no longer satisfy the pleasure of smokers, and smokers develop tolerance to nicotine as a result. When smokers stop smoking for several hours (sleep time), the nicotine content in the body decreases and the neural receptors become abnormally sensitive. At this point, the activity of acetylcholine exceeds normal levels, causing the smoker to become irritable and eager to smoke. Smoking at this time can overstimulate neuronal receptors and promote the release of large amounts of dopamine. Through this phenomenon, we can understand why the first cigarette of the day can bring great pleasure to "old smokers", and smokers are thus trapped in a vicious cycle of increased smoking addiction

The first ambassador to use tobacco as a medicine - in 1560, when tobacco was not yet popular, Jean Nico, the French ambassador to Portugal, sent tobacco back to his country as a medicine for treating many diseases. Hundreds of years later, chemists finally revealed that the medication used to treat diseases in tobacco was a harmful substance and named it nicotine

Currently, smoking cessation products appearing on the market have not been able to truly solve the problem of quitting smoking. People always quit and relapse. Cigarettes contain more than 2540 components, which undergo complex physical and chemical changes after combustion. The smoke produced contains more than 400 carcinogens, as well as more than 10 substances that promote cancer development. Among them, the most harmful substances to the human body are radioactive substances such as nicotine, tar, carbon monoxide, cyanide, and polonium-210
