Nicotine is a dangerous and addictive drug that, once inhaled, will reach the brain in less than 15 seconds. Since nicotine affects the brain, the powerful chemicals can alter brain activity and have a significant impact on one’s mood. Nicotine has been linked to certain cancers and respiratory diseases. In fact, approximately 50% of all individuals who smoke will die of smoking related illnesses.
According to Healthline.com, “Nicotine can be absorbed through the skin, the lining of the mouth and nose, and the moist tissues lining the lungs.” Nicotine quickly enters the blood stream where it circulates toward the brain. Cigarettes are the fastest delivery mechanism of nicotine to the brain. Studies have shown that those who die of smoking related causes shorten their lives by over 10 years.
The Dangers of Smoking
According to the American Heart Association, “Nicotine causes a short-term increase in blood pressure, heart rate and the flow of blood from the heart. It also causes the arteries to narrow. The smoke includes carbon monoxide, which reduces the amount of oxygen the blood can carry.” Healthline.com indicates, “About 90% of lung cancers are linked to smoking. Smoking also causes such other lung problems as chronic bronchitis and emphysema, as well as worsening the symptoms of asthma.”
Nicotine Addiction
Once the powerful nicotine drug reaches the brain, dopamine is released. Dopamine is a chemical in the brain connected to feeling good. This release of dopamine creates pleasurable sensations that are felt literally seconds after first inhaling nicotine. Since nicotine affects brain activity, the body quickly adjusts to find a balance for the chemical imbalance created. Soon, the body increases the tolerance level for nicotine and more nicotine is needed to achieve the pleasurable sensations felt when smoking. (Healthline.com, 2009)
Can a Person Quit Smoking
Quitting smoking is an incredible challenge. When the body is not receiving the levels of nicotine previously introduced, the brain feels that sense of imbalance. There are notable physical withdrawal symptoms, some of which include:
- irritability
- depression
- anxiety
- sleeplessness
- decreased heart rate
- coughing
There are many programs, medications and alternative methods available to aid individuals who want to stop smoking. Unfortunately, there is not a high rate of success and the body will encounter the effects of withdrawal. The best way to quit smoking is to quit without substituting alternate forms of nicotine. Further, quitting smoking will reverse or reduce the health related issues on the body so trying to quit at any time is well worth the task!
