Nicotine is what addicts and keeps people using tobacco products, but it is not what makes tobacco use so deadly. It is this mix of chemicals—not nicotine—that causes serious disease and death in tobacco users, including fatal lung diseases, like chronic obstructive pulmonary disease (COPD) and cancer

Tobacco contains a toxic mix of more than 7,000 chemicals

How Nicotine Affects Individual:

Addiction:

Nicotine can lead to addiction because nicotine can change the way the brain works, causing cravings for more of it. Some tobacco products, like cigarettes, are designed to deliver nicotine to the brain within seconds, making it easier to become dependent on nicotine and more difficult to quit.

Adolescent Brain Development:

Young people are the most at risk for nicotine addiction because their brains are still developing.

In fact, the younger a person is when they start using tobacco, the more likely they are to become addicted and hinder brain development such as increased impulsivity and mood disorders.

Pregnancy and Fetal Health:

If pregnant women use tobacco products, nicotine can cross the placenta and result in multiple adverse consequences. These outcomes may include but are not limited to: premature labor; low birth weight; respiratory failure at birth; and even sudden infant death syndrome (SIDS).

FDA Research :

Cigarette smoking causes more deaths each year than AIDS, alcohol, illegal drug use, homicide, suicide, and motor vehicle crashes combined

  • 163,700 deaths from cancer;
  • 160,600 deaths from cardiovascular and metabolic diseases, and;
  • 113,100 deaths from pulmonary diseases

What does Nicotine do to your brain?

Most people understand how smoking affects the lungs and heart, but what’s less known is the impact that nicotine has on the brain.

  • Nicotine also activates dopamine signals, creating a pleasurable sensation
  • Nicotine also stimulates the pleasure centers of the brain, mimicking dopamine, so your brain starts to associate nicotine use with feeling good.
  • The nicotine in cigarettes changes your brain, which leads to withdrawal symptoms when you try to quit. When this happens, you may experience a variety of side effects including anxiety, irritability, and a strong craving for nicotine.
  • They also suffer from Cognitive decline typically happens naturally as you get older. You may become more forgetful or not be able to think as quickly as you did when you were younger.
  • Smokers also have an increased risk of dementia, a condition that can affect memory, thinking abilities, language skills, judgment, and behavior. It may also cause personality changes.
  • The longer you smoke, the higher your risk of greater age-related brain volume loss.
  • Smoking increases the risk of a stroke by two to four times in both men and women.

National survey data show 68% of current adult smokers in the United States want to quit, and although about 55% of adult smokers have attempted to quit in the past year, only 4 to 7 % were successful.

Why do quit attempts fail? Research shows that nicotine, a highly addictive chemical found in the tobacco plant, keeps people smoking even when they know it could shorten their lives and want to stop.

How Smoking affects your Health :

  • Smoking is a cause of type 2 diabetes mellitus and can make it harder to control. The risk of developing diabetes is 30–40% higher for active smokers than nonsmokers.
  • Smoking can increase your risk for cataracts (clouding of the eye’s lens that makes it hard for you to see).

After Effects when you Quit Smoking:

  • Within 2 to 5 years after quitting smoking, your risk for stroke may reduce to about that of a nonsmoker’s.
  • If you quit smoking, your risks for cancers of the mouth, throat, esophagus, and bladder drop by half within 5 years
  • Ten years after you quit smoking, your risk for dying from lung cancer drops by half.
  • Quitting smoking cuts cardiovascular risks. Just 1 year after quitting smoking, your risk for a heart attack drops sharply
