Effects of Smoking on Brain: Things You Need to Know

According to CDC, about half a million Americans die prematurely each year due to smoking or exposure to secondhand smoke.

Tobacco is one of the leading causes of preventable death in the United States. Apart from death rates, tobacco use can increase the Risk for heart disease, lung disease, cancer, stroke, and many other health conditions. Smoking also harms your Brain.

In this blog, you can find the effects of smoking on the brain along with the benefits of quitting.

Impact of nicotine on your brain

Most people understand the impact of smoking on the heart and lungs, but its impact on the brain is lesser-known to people.

Nicotine also mimics several neurotransmitters that send signals to the brain. It is similar in shape to the neurotransmitter acetylcholine that signals the increases in the brain. Nicotine also activates the dopamine signals that create a pleasurable sensation. The brain begins to compensate for the increased signaling activity by reducing the number of acetylcholine.

Nicotine also stimulates the pleasure centers of the brain and mimics dopamine. Your brains start to associate nicotine use while feeling good. Nicotine in cigarettes changes your brain. It leads to withdrawal symptoms when you try to quit. If this happens, you might experience effects including strong craving for nicotine, irritability, and anxiety.

Unfortunately, if symptoms strike, many people try to reach for other cigarettes to ease the effects of withdrawal.

Below are few common side effects of nicotine and smoking on the brain:

Cognitive decline 

It happens naturally when you start getting older. You may also become more forgetful or may not be able to think as quickly as you did when you were younger. If you smoke, you may experience faster cognitive decline than non-smokers.

Increase in risk of dementia

People who smoke often have an increased risk of dementia. It is a condition that affects behavior, judgment, language skills, thinking abilities, and memory. It may also cause personality changes.

Loss of brain volume

The longer you smoke, the higher you are at the risk of greater age-related brain volume loss. A 2017 study suggests that smoking can negatively affect the structural integrity of subcortical brain regions. It also shows that smokers compared to non-smokers had higher amounts of age-related brain volume loss in several areas of the brain.

High risk of stroke

Smokers are likely to suffer from a stroke than non-smokers. Data by CDC show that smoking increases the risk of a stroke by two to four times in both women and men. The risk also increases if you smoke a higher number of cigarettes.

Increases the risk of cancer

Smoking induces many toxic chemicals into the body and brain. These chemicals can cause cancer. Repeated exposure to tobacco, genetic changes in the brain, throat, or lungs may increase the risk of developing cancer.

Are e-cigarettes good?

Even though the research on an e-cigarette is not apt, we know so far that it can impact negatively on your brain and overall health.

National Institute on Drug Abuse states that e-cigarettes that contain nicotine are likely to produce similar changes in the brain as cigarettes.
