Smoking and Nicotine Addiction
Cigarette smoking is highly addictive and is the leading cause of preventable deaths and diseases. In the United States alone, smoking is responsible for over 480,000 deaths annually, including 41,000 due to second-hand smoke. Tobacco use worldwide causes around 7 million deaths each year.
Smoking is linked to a range of health issues, including:
Cancer (such as lung and throat cancer)
Heart disease
Stroke
Gum disease
Asthma and other chronic lung conditions
Type-2 diabetes
In 2017, approximately 14% of U.S. adults smoked cigarettes, and studies show that nearly 70% of them wanted to quit. People with mental health conditions such as depression and anxiety are more likely to smoke, often using it as a coping mechanism. However, smoking does not provide a legitimate treatment for mental health issues.

The Causes and Consequences of Smoking
Nicotine addiction, also known as nicotine or tobacco dependence, often begins in adolescence. Many people who start smoking are influenced by friends or family members who also smoke. The earlier someone begins smoking, the greater their likelihood of becoming addicted to nicotine, which is the addictive substance in tobacco.
In the short term, nicotine may offer a temporary distraction from unpleasant emotions or stress. However, once a person becomes dependent on nicotine, they experience withdrawal symptoms—both physical and mental—that can last for days or weeks, making quitting extremely difficult. Despite knowing the severe health risks, many people continue smoking due to the strong addiction and dependence on nicotine.
The consequences of this addiction are far-reaching, affecting not only physical health but also emotional and social well-being. Quitting smoking, though challenging, is essential for reducing the risk of various serious health conditions.
How to Quit Smoking
Quitting smoking at any age can significantly improve a person’s health, and the earlier one quits, the greater the health benefits. There are various strategies available to help individuals break the smoking habit, including substitutes for cigarettes and supportive therapies.
Nicotine replacement products, such as nicotine gum, lozenges, or patches, are FDA-approved methods that can help manage withdrawal symptoms. These products work by providing the body with a controlled amount of nicotine, reducing cravings as the person gradually reduces their dependence on nicotine. When combined with behavioral treatments—such as self-help materials, counseling, group sessions, or cognitive behavioral therapy—these methods can significantly increase the likelihood of long-term success.
Additionally, medications like bupropion and varenicline are sometimes prescribed to help individuals remain smoke-free. These medications may improve the chances of quitting, though potential side effects like anxiety and depression should be considered before starting treatment.
Quitting smoking can be challenging, but with the right combination of support, therapy, and medications, it is entirely achievable and offers life-changing health benefits.
What to Know about Vaping
Vaping, often used by smokers as a substitute for traditional cigarettes, involves inhaling aerosolized nicotine and other chemicals through e-cigarettes. While e-cigarettes generally contain fewer chemicals than regular cigarette smoke, they still pose potential health risks due to substances like diacetyl (linked to lung disease), fine particles, and harmful metals like nickel, tin, and lead. Vaping devices, though often marketed as safer alternatives, are considered unsafe for teens and pregnant women. While e-cigarettes have shown some potential in helping smokers quit, they are not FDA-approved as smoking cessation aids, and research suggests that while vaping may be more effective than nicotine replacement therapy in the short term, users tend to continue vaping longer. Vaping has also been associated with respiratory illnesses, such as EVALI, a serious lung injury linked to poor-quality THC products used in vaping. Despite its rare occurrence, EVALI is a significant concern in the vaping community.
