Fagerstrom Test for Nicotine Dependence Calculator

The Fagerstrom Test for Nicotine Dependence calculator was created to assess the intensity of an individual's physical addiction to nicotine. It is based on the Fagerstrom Test for Nicotine Dependence (FTND) — a questionnaire that was developed by Karl-Olov Fagerstrom and then modified by Todd Heatherton. Read the article below to learn more about the Fagerstrom score and its interpretation.

We try our best to make our Omni Calculators as precise and reliable as possible. However, this tool can never replace professional medical advice.

The Fagerstrom Test for Nicotine Dependence is based on Fagerstrom Tolerance Questionnaire, which was created by Karl-Olov Fagerstrom in 1978. The questionnaire was modified in 1991 when the revised version – the Fagerstrom Test for Nicotine Dependence – was presented.

FTND provides an ordinal measure of nicotine dependence related to cigarette smoking. You can calculate the entity of nicotine addiction with our HSI calculator (heaviness of smoking index).

It contains 6 questions that are related to the following:

• Quantity of cigarette consumed (the pack year calculator can help you quantifying this amount);
• Urge to use; and
• Dependence.

The Fagerstrom Test for Nicotine Dependence can be used by a doctor to assess the intensity of physical addiction to nicotine, e.g., when documenting indications for prescribing medication for nicotine withdrawal.

Cigarettes are highly addictive because they contain nicotine. Cigarette smoking is associated with many health problems, including lung cancer, chronic obstructive pulmonary disease, and heart disease. It doesn't matter how long you have smoked for — quitting smoking can improve your health. If you are fighting with nicotine addiction, check our smoking recovery calculator, which will show you the process of recovery after smoking cessation, and the smoking cost calculator, which will estimate your potential savings if you decide to quit smoking.

Each "Yes"/"No" question scores 1 or 0 points, respectively, whereas multiple-choice questions can score from 0 to 3 points. Therefore, the total Fagerstrom score can range from 0 to 10 points.

We present the interpretation of the results (Fagerstron scale) in the table below:

As you can see, the higher the total Fagerstrom score, the more severe the physical dependence on nicotine is.

To assess your Fagerstrom test score, begin with the initial question — "Do you currently smoke?".

If your answer is negative, that's great — you are not nicotine dependent 🙂. If your answer is positive, the Fagerstrom Test for Nicotine Dependence will be displayed. As we have mentioned above, it consists of 6 questions, and, for each question, you should choose the option which describes your response best. Based on your answers, you will see your total score and the interpretation of the results, both at the bottom of the calculator.
