How Nicotine Affects the Body?

Nicotine can affect your body in many ways. When nicotine is inhaled through cigarette smoke, it is absorbed rapidly into the blood. It affects the brain in 10 seconds. Nicotine can trigger chemical reactions that can boost pleasure and concentration.

These feelings are found to be short-lived. They subside within minutes. When it is taken for the long term, it can affect many parts of the body, such as the brain, skin, heart, and lungs.

  • Brain:

Nicotine can change the chemistry in your brain. This may lead to the development of many psychological disorders, like bipolar disorder and major depressive disorder.

  • Skin:

Nicotine constricts blood vessels. This may prevent the nutrients from reaching the skin. This causes wrinkles and premature aging.

  • Heart:

Nicotine can increase the heart rate and blood pressure. Apart from this, it can narrow the arteries. This may further cause an increased risk of a heart attack.

  • Lungs:

Smoking nicotine can limit your lung capacity in the long run. This causes chronic obstructive pulmonary disease (COPD) later.

How Long Does Nicotine Stay in Your System?

Nicotine may be detectable for a few hours to a few months after its use. It enters the bloodstream quickly. Then it is metabolised in the liver and breaks down to its byproducts, like cotinine. Liver detoxification helps in the removal of nicotine.

Nicotine has a half-life of two hours. This means that half of the nicotine is gone from your body in two hours after its use. Even then, its byproducts tend to stay back in your system for a longer duration. This again may vary from one person to another.

Nicotine and cotinine (its byproduct) can remain in your body for a few hours to several days. Among a few individuals, traces may remain beyond these days. How long the nicotine stays in your system again depends on certain factors, like the type of nicotine product, frequency of use, and how your body processes it.

Which Factors Affect How Fast Nicotine Leaves Your Body?

Many factors affect how fast the nicotine is processed in our bodies. These include:

  • Genetics:

In some individuals, due to genetic variations, nicotine may stay for a long time. Those with slow metabolism due to variations in genes keep the nicotine in their body for a long time.

  • Age:

When age increases, your body slows down the processing of nicotine. This effect may be different from person to person.

  • Sex:

Women with hormonal changes, particularly those who are pregnant, or those who take birth control pills, tend to clear nicotine faster than men from their bodies.

  • Body mass:

Your weight and body mass index (BMI) affect how fast your body processes your nicotine.

  • Frequency of use:

Those who use nicotine more frequently tend to build up nicotine levels when compared to those who use nicotine occasionally.

  • Type of tobacco product used:

If smokeless tobacco is used, this causes long-lasting nicotine in the body when compared to other types of tobacco used.

What Actually Helps Nicotine Leave Your System Faster?

Many ways help flush nicotine from the body. These include:

  • Drinking plenty of water helps remove toxins from the body, including nicotine. Nicotine is removed through urine. Hence, drinking plenty of water makes a person urinate more and allows nicotine to be removed through urine.

  • Eating foods that stimulate liver enzymes. These enzymes help remove nicotine faster. Foods such as garlic, onion, egg yolk, and vegetables can stimulate liver enzymes, and hence, there is an increase in bile production.

  • When vitamin C supplements are taken, they help increase the speed of metabolism. When the speed of metabolism increases, it removes the nicotine faster. Naturally rich in vitamin C are oranges, strawberries, papaya, and kiwi.

  • Doing cardio exercise helps in raising heart rate and sweat. Nicotine is removed through sweat as well. Hence, doing exercise can speed up the removal of nicotine from your body.

  • Visiting a sauna or being in a hot climate can cause sweating. As nicotine is removed through sweat, this method can be used to remove nicotine fast.
