What Is the Fagerstrom Test for Nicotine Dependence?

The Fagerstrom Test for Nicotine Dependence (FTND) is a validated six-item questionnaire that measures the intensity of physical addiction to nicotine from cigarette smoking. It evolved from the Fagerstrom Tolerance Questionnaire (1978) and was revised in 1991. Clinicians use FTND scores to guide smoking cessation counseling and nicotine replacement therapy decisions.

How FTND Scoring Works

The test includes one yes/no item about current smoking plus six dependence questions. Yes/no items score 1 or 0 points. Multiple-choice items score 0 to 3 points depending on the answer. Total scores range from 0 to 10.

• 0 to 2: Very low dependence
• 3 to 4: Low dependence
• 5: Medium dependence
• 6 to 7: High dependence
• 8 to 10: Very high dependence

Higher scores indicate stronger physical dependence on nicotine and may suggest a need for structured quit support or medication.

When to Use This Calculator

Use the FTND if you currently smoke and want a quick self-assessment of nicotine dependence. If you do not smoke, the tool confirms that FTND does not apply.
