Exposure and screening numbers can be useful when they are treated as context rather than judgment. Fagerstrom Test for Nicotine Dependence Calculator summarizes the specific behaviors or amounts entered into one transparent result.

What this calculator does

Fagerstrom Test for Nicotine Dependence Calculator uses Do you currently smoke?, How soon after waking do you smoke?, Difficult to refrain where smoking is forbidden?, Which cigarette would you hate most to give up?, Cigarettes per day, Smoke more frequently during first hours after waking?, and Smoke even when ill in bed? to calculate Fagerström nicotine-dependence score. It is built around the exact fields displayed in this plugin rather than a generic version of the topic. Substance-use calculators can organize exposure or screening information, but they cannot determine impairment, withdrawal safety, diagnosis, or prognosis on their own. When there is risk of overdose or dangerous withdrawal, clinical care takes priority over the score.

How to use it

Complete the requested fields, including Do you currently smoke?, How soon after waking do you smoke?, Difficult to refrain where smoking is forbidden?, Which cigarette would you hate most to give up?, Cigarettes per day, and Smoke more frequently during first hours after waking?, then finish the remaining items shown in the calculator. Confirm that each yes/no, category, date, or score option is applied exactly as labeled. Keep amounts, dates, and questionnaire answers within the same exposure or screening timeframe requested by the tool.

How the calculation works

For current smokers, the Fagerström score adds the embedded points for time to first cigarette, difficulty refraining, the cigarette hardest to give up, cigarettes per day, heavier morning smoking, and smoking while ill. The calculator labels 0–2 very low, 3–4 low, 5 medium, 6–7 high, and 8–10 very high dependence. If “not currently smoking” is selected, it returns zero.

Example

Using the sample values prefilled in this calculator, the primary result is 3 points (Low dependence). This worked example shows how the plugin’s own default inputs flow through the implemented method; replace them with the correct patient, laboratory, imaging, or personal values before interpreting a result.

How to interpret the result

Higher scores reflect stronger cigarette nicotine dependence in the questionnaire model. The categories help communicate dependence intensity and can support cessation planning, but they do not predict who can or cannot quit.

Limitations and notes

The Fagerström score describes cigarette nicotine dependence and does not measure the full severity of tobacco-use disorder or include vaping and other nicotine products. Treatment choice also depends on prior quit attempts, preferences, contraindications, and behavioral support.
