Nicotine
2. One drop of nicotine (40 to 60 mg) can kill the average human.
3. Cigarettes in the US typically contain approx. 9 milligrams of nicotine, most of which is burned off during smoking, leaving the body to absorb about 1 milligram of it.
4. Nicotine enters the human body riding on particles of tar within cigarette smoke.
5. When nicotine enters the human body, the following are typical effects: increased blood pressure, heart rate and blood flow from the heart; narrowing of arteries; and a reduction in amount of oxygen in the blood (since the blood is tasked with carrying carbon monoxide).
6. After smoking, nicotine typically remains in the smoker's blood for six to eight hours.
7. Nicotine is named for the plant it's derived from, Nicotiana tabacum, which itself was named for mid-1500s French ambassador Jean Nicot. Nicot brought tobacco to Paris from Portugal, extolling its supposed medicinal properties.
8. Nicotine has a similar effect on the body as cocaine and heroin, activating the brain's reward system typically set off by addictive substances. Some studies have suggested nicotine may be even more addictive than cocaine and other illegal drugs.
9. Chewing tobacco often puts more nicotine into your bloodstream than cigarettes do. Further, people who use chewing tobacco often develop a high tolerance to nicotine and end up switching brands to those that contain more and more nicotine, and chew more often, to feel the desired effects.
10. When a smoker attempts to quit smoking, the nicotine withdrawal typically exhibits itself in several or all of the following: irritability, impatience, hostility, anxiety, depressed mood, difficulty concentrating, restlessness, decreased heart rate, and increased appetite or weight gain.
