Physiological Results Of Nicotine

Nicotine is one of the more than 4,000 substances present in cigarette smoke. It is an addictive drug that affects the brain, heart and lungs of the smoker.


Nicotine increases the level of dopamine in the brain. Researchers believe this leads to pleasurable sensations causing physical addiction similar to that of heroin.


Immediately after smoking a cigarette, a person's adrenaline levels dramatically increase. This leads to rapid heartbeat, rapid shallow breathing and increased blood pressure.


The circulatory system is affected by nicotine. Nicotine causes blood vessels to constrict. Nicotine also raises the "bad" blood cholesterol, LDL. As a result smokers have an increased risk of heart attacks and strokes.


Enhanced memory and attention spans are a result of nicotine ingestion. Nicotine also raises metabolism, which leads to weight loss. Smokers on average weigh 6 to 9 lbs. less than nonsmokers of similar height and age. Nicotine also increases blood sugar levels, which can contribute to weight loss.


Nicotine withdrawal causes confusion, fatigue, irritability and depression which lasts between 3 and 21 days.
