Nicotine can make people addictive or dependent (one of the hardest addictions to quit), people often have difficulty restraining themselves, and repeated use of nicotine also increases heart speed and blood pressure and reduces appetite. Large doses of nicotine can cause vomiting and nausea, and in severe cases, death.

Nicotine is often found in tobacco, which makes it impossible for many smokers to quit their cravings.

So why do some people smoke more than they get poisoned? There are many people who smoke more than a box of cigarettes (20 cigarettes) every day, and the nicotine content greatly exceeds the lethal amount of people, but there are very few deaths from acute poisoning, because some of the nicotine in tobacco is neutralized by the toxic formaldehyde in the smoke, and most of them are not continuous smoking, and these nicotine are intermittent and slow into the human body. In addition, 50% of the nicotine in the cigarette is diffused into the air with the smoke after ignition, 5% is thrown away with the cigarette butt, 25% is destroyed by combustion, and only 20% is absorbed by the body.
