This cigarette calculator will help you estimate your lifetime exposure to cigarettes. Do you know how many cigarettes you smoke daily? Do you remember for how many years, months, or maybe weeks you have been smoking? Let's count!

Smoking increases the risk of premature death and health complications and lowers life expectancy. Moreover, there are more and more smoking-related cancers discovered. Some research state that for every 15 cigarettes, a smoker's DNA alter irreparably.

We try our best to make our Omni Calculators as precise and reliable as possible. However, this tool can never replace a professional doctor's assessment.

Is cigarette smoking an addiction?

Tobacco is highly addictive as it affects the pleasure and reward systems of the brain.
What are the symptoms of being addicted to tobacco? Among others:

  • You cannot stop smoking it, even though you try.
  • You have shaky hands, sweat a lot or have heart palpitations when trying to quit (withdrawal symptoms).
  • You feel the need to smoke after a meal, when you are stressed due to work, etc.
  • You keep on smoking even though you are already experiencing some health consequences.

How does the cigarette calculator work?

First, you have to either know how many cigarettes or how many packs you smoke a day. Then input how long you have been smoking for - in years, months, weeks, or even maybe days. And that's it! The result is the total number of cigarettes you have smoked in your life - a rough estimation of course.

Let's take a look at Joe.
Joe smokes five cigarettes daily, so one-fourth of a pack every day. He started at the age of 20; now, Joe is 45 years old and has been smoking for the past 25 years.
How many cigarettes has he smoked so far?

5 cigarettes/day x 25 years = 45,656 cigarettes

What are the risks of smoking?

Smoking is closely associated with an increased risk of contracting numerous diseases and conditions, such as:

  • Lung cancer;
  • Larynx cancer;
  • Bladder cancer.

As well as:

  • Coronary heart disease;
  • Stroke.

In some types of lung cancer, at least 80 percent of cases can be attributed to smoking. If you want to calculate the risk of suffering from lung cancer, you can estimate it with our lung cancer risk calculator. It depends on the number of "pack-years", the number of years you have been smoking multiplied by the number of packs of cigarettes smoked daily. For that calculation, use the pack year calculator.

Don't forget that smoking affects not only your health, but also the health of your family and friends. Did you know that passive smoking is almost as dangerous as active smoking? Cancer, COPD, and other lung diseases are caused not by nicotine but mostly by tar and other chemicals, easily inhaled by second-hand smokers. Take a look at our smoking recovery calculator and see how much your life might improve by after quitting.

Apart from the health consequences, smoking significantly reduces your daily budget. Want to know how much? Check it out with our quit smoking and save calculator. Just imagine what you could buy yourself in ten years if you quit now. Are you running a company and wonder how much you're paying your employees to smoke?
