Deck,
Sorry, I did not mean to down play the addictive effects of nicotine. Nicotine is an extremely, if not one of the most addictive substances and one of the hardest addictions to break. If it were not, we would not all be here today!
Nicotine is also a harmful substance. When smoked in a cigarette, it is distributed through the body via the blood stream in approximately seven seconds and crosses the blood-brain barrier causing a variety of effects in the body. Nicotine acts on the brain to increase adrenaline which in turn causes constrictions in blood vessels increasing heart rate, blood pressure, respiration and blood glucose levels. When smoked in cigarettes, nicotine also rapidly increases dopamine levels in the body producing feeling of relaxation, calmness and alertness.
When used as a therapeutic; in the case of NRTs, controlled levels of nicotine are released into the body and make their way into the blood stream more gradually and steadily throughout the day.
In response to Faith�s question, if your using the patch, does it change any of the health benefits of quitting, the answer is no, not really except for those that are directly related to nicotine. Many of the harmful effects of cigarettes are not caused by nicotine but by the many other substances and chemicals that are in cigarettes such as carbon monoxide, tar, formaldehyde, benzene and arsenic. Nicotine is the substance that causes the addiction to cigarettes so you are all on the right track here fighting the Nicodemon to rid your bodies of the many other harmful substances found in cigarettes. Many of the health benefits described above are still seen even when using an NRT.
