In this article we will discuss the negative effects of nicotine on the body and overall health.

Nicotine smoke primarily affects lungs and heart and may cause different health problems related to these organs. Nicotine is a habit-forming substance because it destroys important enzyme in the brain that regulates production of neurotransmitter dopamine which is associated with pleasure. Without this enzyme, dopamine is over secreted and it causes you to crave cigarettes more. When a person smokes a cigarette, he or she usually feels relaxed and filled with energy but the long term effects on the body are pretty damaging to health.

Long Term Effects of Nicotine

Nicotine use leads to increased heartbeat and elevated blood pressure while it relaxes the mind. There are number of negative effects of nicotine on the body organs that smokers should keep in mind.

Effects of Nicotine on the Heart

It has been proven that nicotine use can cause heart attack and stroke. Nicotine causes arteries to constrict which contributes heart attack. Also, nicotine releases hormone epinephrine that is responsible for increased heart beat, high blood pressure and elevated sugar. This hormone also speeds up breathing rate because the heart has to pump more blood through the body. Blood flow to the brain is restricted due to nicotine which leads to increased risk of stroke.

Effects of Nicotine on the LungsSmoking impairs ability of the lungs to eliminate germs and dirt. Nicotine can cause persistent coughing and wheezing and lead to chronic obstructive pulmonary disease such as emphysema and chronic bronchitis. Nicotine also exacerbates asthma symptoms. Additionally, cigarette smoking is associated with around 90% of lung cancer cases.

Effects of Nicotine on the Immune SystemDue to nicotine use people are more susceptible to infections and inflammations because it affects production of specific type of white blood cells. These white blood cells fight against infections and without them function of the immune system is weakened.

Effects of Nicotine on the Teeth

Nicotine has damaging effect on the teeth and general dental health. Nicotine use causes yellowing of the teeth and thinning of the gums. Due to this, the root of the teeth is exposed to bacteria which can infect the gums. This may cause bad breath as well.
