It has an important part in regulating mood and pleasure, both serving as a trigger for the synthesis of adrenaline and noradrenaline and acting as a neurotransmitter. When nicotine goes to the brain, it produces a rush of dopamine into the bloodstream, causing the user to become more relaxed and calm. In this respect, nicotine's chemical action is very similar to such other drugs as cocaine, amphetamines ,and morphine. In effect, each time a smokeless tobacco user puts a pinch of tobacco in his or her mouth or inhales some powder, he or she gets a powerfully reinforcing and rewarding chemical message from the brain that, over a short period of time, will cause physical and emotional dependence on tobacco. However, because the body quickly becomes used to nicotine through a process called "tolerance," users experience a gradual rise in the amount of tobacco they need to get the same physiological…
