Dangers Of Smoking With Nicotine

One of the main dangers of smoking is due to Nicotine. Nicotine is found naturally in tobacco. It has no odor and no color. It is, however, both physically and psychologically addictive, and it causes those who use it to want to smoke one cigarette after another.

Nicotine enters the body as tiny droplets resting on particles of tar in cigarette smoke. Inhaled into the lungs, the drug passes quickly into the bloodstream, reaching the brain within about 10 seconds. In another 5 to 10 seconds the nicotine has spread to all parts of the body.

The nicotine raises both the heart rate and blood pressure. The smoker quickly feels more alert and relaxed. In less than 30 minutes, however, about half of the nicotine has left the bloodstream, and the smoker starts feeling less alert, more edgy.

So he or she reaches for another cigarette to get a new “hit” of nicotine. Over time, the smoker starts needing more cigarettes throughout the day to satisfy the craving.
