Most of the emphasis on the harmful effect of tobacco has been centered on cigarettes, but much less on chewing or " smokeless" tobacco, It has been proved beyond a doubt that smoking caused lung cancer and other fatal diseases. Chewing tobacco has been linked with throat and mouth cancer, a major concern. Chewing tobacco is also a source of nicotine, and addictive substance. Nicotine acts lie an injection of adrenaline, increasing pulse rate and blood pressure, which makes the heart work fasted an harder, so that the heart actually needs more oxygen, Chewing tobacco will result in increased levels of nicotine in the blood and the problems associated with its addictive qualities. Research on addiction indicated that nicotine works much like heroin, cocaine, and alcohol. When nicotine was give to volunteers intravenously (into veins), many of them could not tell the difference between the effect of nicotine and that of cocaine. Nicotine produced pleasurable sensations and physical dependency by affecting the brain and spinal cord.
It is important to remember that tobacco use (both smoking and chewing) has associated health risk and its use will prevent you from attaining your highest health potential.
