What do cigarettes do


Cigarettes are a form of tobacco product that have been around for centuries. They contain nicotine, tar, and many other chemicals that are detrimental to health. When someone smokes a cigarette, these chemicals enter the bloodstream and can cause a variety of health problems, both short-term and long-term.

In this article, we’ll discuss the dangers of smoking and why people should avoid smoking cigarettes.

Overview of Cigarette Use

Cigarettes are a type of tobacco product that consists of cured and finely cut tobacco leaves wrapped in thin paper. Smoking cigarettes is very common in many parts of the world, and has had a profound impact on public health, both positively and negatively. While smoking cigarettes can reduce stress, it also poses significant risks to physical health and well-being due to the chemicals contained in the smoke.

Cigarette use is also linked to numerous long-term health conditions such as cancer, stroke, emphysema, chronic bronchitis, heart disease, infertility, and low birth weights—all of which could have serious implications for life expectancy. In addition to physical health concerns, smoking cigarettes may cause or worsen mental illnesses such as depression or anxiety disorders.

When people smoke cigarettes they usually start with a few puffs from one cigarette evoking nausea or other unpleasant reactions followed by more frequent smoking. Over time bodies become accustomed to nicotine which can change brain chemistry among users creating psychological addiction along with physical dependency on nicotine over time.

The cigarette does not need to be lit for nicotine absorption; nicotine patches are available as an alternative form of consumption that avoids inhalation of any fumes. Additionally there have been attempts in the past at producing smokeless cigarettes which involve some form of aerosolized liquid containing nicotine without flame or smoke produced by burning tobacco as well as certain disposable devices called e-cigarettes or vapes that contain liquid nicotine cartridges known as Juuls or vape pens.

Types of Cigarettes

Cigarettes are available in a variety of types and brands, all with different levels of nicotine and other chemicals. The type of cigarette you choose can be an important factor when it comes to your health.

There are three main types of cigarettes: full-flavor, light, and ultra-light cigarettes. Full-flavor cigarettes, which typically have the highest nicotine content and the most tar, are usually considered to be the most harmful type. Light cigarettes have less nicotine and tar than full-flavor but still contain dangerous chemicals that have been linked to various forms of cancer such as lung cancer. Ultra-light cigarettes contain the least amount of nicotine and tar out of all three kinds but still contain the same dangerous chemicals found in full-flavor and light cigaretts.

No matter what type of cigarette you choose to smoke, they all contain toxins that can harm your health. Smoking any kind of cigarette can increase your risk for various cancers such as lung cancer, bladder cancer and oral/throat cancer as well as respiratory diseases such as COPD and emphysema. Quitting smoking is the best way to reduce these risks; however it is important to understand the different types available so you can make informed decisions about your own health.

Health Effects

Cigarette smoking is the leading preventable cause of death and disease in the United States. Cigarette smoking can have serious health effects, ranging from cancer and heart disease to respiratory and reproductive issues.

This section will discuss the short-term and long-term health effects of smoking cigarettes.

Short-term Health Effects

Cigarettes contain a wide range of toxic and carcinogenic chemicals that lead to a variety of short-term health effects. As soon as 20 minutes after smoking a cigarette, blood pressure and heart rate can increase. The smoker’s heart also pumps about 15-20% more blood than usual with each beat, placing extra strain on the circulatory system. These elevated levels of activity return to normal 40 minutes after smoking stops.

Other physical effects include headache, dizziness, nausea and reduced lung capacity which all occur soon after inhaling cigarette smoke. These can be accompanied by decreased appetite, increased stress levels and cravings for more nicotine during the withdrawal phase. Nicotine is highly addictive but additional compounds in cigarettes make them even more difficult to quit than many other addictive substances.

Smoke from a burning cigarette also affects those around the smoker, often called “secondhand smoke” or “environmental smoke”. Long-term exposure to secondhand smoke has been implicated as a cause of many serious illnesses including cancer and cardiovascular disease in non-smokers – even children – so it is important to eliminate smoking in public places whenever possible.

Long-term Health Effects

It’s no surprise that smoking cigarettes is terrible for your health – it’s well established that cigarettes can cause serious and long-term health problems. Smokers face an increased risk for major diseases, such as cancers of the lung, mouth, throat, esophagus and bladder.

In addition to this, smoking also increases the risk of:

  • Heart disease
  • Stroke
  • Chronic bronchitis
  • Emphysema
  • Cataracts
  • Gum disease
  • Type 2 diabetes
  • Impotence in men

There’s also evidence that smoking may increase the risk of rheumatoid arthritis, colorectal cancer and age-related macular degeneration. Even if you don’t smoke but have been exposed to secondhand smoke, you’re at an increased risk for diseases like coronary heart disease and stroke. Unfortunately, these risks remain even after quitting smoking.

The good news is that your body will start to heal itself within days after you stop smoking – eventually repairing much of the damage caused by years of smoking.

Secondhand Smoke

Secondhand smoke, also known as involuntary or passive smoking, occurs when a person breathes in smoke coming from the burning end of a cigarette, pipe, or cigar, as well as in the smoke exhaled by smokers. This kind of smoke is dangerous to both smokers and non-smokers alike.

Research suggests that secondhand smoke affects smokers even more than active smoking because particles suspended in the air linger longer after being released. Non-smokers are also at risk of experiencing physical and psychological health problems associated with long-term exposure to secondhand smoke. For example, non-smokers exposed to secondhand smoke have an increased risk of developing:

  • Lung cancer
  • Heart disease (e.g., stroke)
  • Respiratory infections such as asthma and chronic obstructive pulmonary disease (COPD)
  • Poor overall health status

These risks are present whether you are directly exposed to secondhand smoke or if you simply reside in close proximity with a smoker.

In addition to posing a serious threat for respiratory diseases and other illnesses, exposure to secondhand smoke can also weaken the immune system’s ability to ward off diseases such as tuberculosis and pneumonia. Even short-term exposure can cause persistent coughing and chest discomfort due to irritation caused by particulate matter from tobacco products.


One of the biggest implications of smoking cigarettes is addiction. Cigarettes contain nicotine, a highly addictive chemical that causes a person’s body to crave more after the first cigarette. Eventually, it can lead to physical withdrawal symptoms or cravings when a person abstains from smoking. Depending on the number of cigarettes smoked per day and the length of time smoking has been taking place, symptoms vary but can last anywhere between just a few minutes to days or weeks at a time.

In addition to physical addiction, psychological addiction can occur with smoking cigarettes as well. When people smoke regularly they may become accustomed to the routine and use cigarettes as an emotional crutch in times of stress or difficulty.


Quitting smoking is the most important thing you can do for your health. Cigarettes contain over 7,000 chemicals, including over 70 carcinogens, which can cause cancer. Quitting smoking can improve your overall health in many ways and reduce your risk of developing health problems, such as heart disease, stroke, and lung cancer.

Let’s take a look at how quitting smoking can help you become healthier:

Benefits of Quitting

Quitting smoking can reduce your risk of developing serious, long-term health problems and improve your overall quality of life. Some of the benefits of quitting smoking are immediate, while others will become apparent over time.

  • Immediate Benefits
  • Reduced risk of cardiovascular disease
  • Improved lung function
  • Lower blood pressure
  • Reduced risk of respiratory illnesses
  • Decrease in chance of fire hazards in the home
  • Reduced exposure to air pollutants
  • Long Term Benefits
  • Lower risk for cancers and other diseases associated with smoking
  • Improved taste and smell senses
  • Improved fertility rates amongst females who smoked before pregnancy
  • Reduced stress levels due to nicotine withdrawal

Quitting smoking is one of the best things you can do for your health. Even if you’ve been smoking for years, quitting will help reverse some damage to your body in a very short amount of time. You are never too old or too late to quit!

Strategies for Quitting

Quitting smoking is not easy, but it can be done. It requires extinguishing conditioned behavior, breaking ingrained habits, and managing symptoms of withdrawal. Evidence suggests that more committed and comprehensive quit attempts that involve multiple methods for overcoming nicotine dependence are more likely to result in success.

A few of the approaches used to help smokers quit include:

  • Self-help booklets
  • Telephone support hotlines
  • One-on-one counseling with a health professional
  • Nicotine replacement therapy (e.g., patches or gum)
  • Drug therapy (e.g., varenicline or buproprion)
  • Internet based cognitive behavioral interventions

Using multiple strategies can increase the likelihood of success: each smoker must find his/her own successful combination of strategies that will lead to long-term abstinence and reduced risk of relapse. It has been scientifically proven that individuals who completely stop cigarette smoking can improve their overall health and life expectancy within one to five years after quitting.


At their core, cigarettes are highly toxic and can cause severe damage to your health, from cancer and heart disease to lung disease. It’s important to remember that the risks of smoking reach beyond those associated with the primary product itself.

Second-hand smoke can be just as dangerous as smoking directly, presenting an even greater risk of adverse effects on a person’s health. Moreover, being around a smoke-filled environment constantly can adversely affect your respiratory system, leading to asthma and other illnesses.

Given the significant risks posed by cigarettes and tobacco products, it is strongly recommended that people think carefully before taking up this habit. If they already choose to smoke, they should be aware of steps they can take to reduce their risk of serious illness. This includes:

  • Limiting their exposure to second-hand smoke.
  • Making sure they have access to medical attention if needed.

Further education regarding tobacco products along with increased public awareness is paramount for reducing the number of smokers worldwide as well as providing effective options for those who cannot quit cold turkey or may benefit from topical medications or nicotine replacement therapy products such as gums or patches.
