How this instrument works
The Fagerström Test for Nicotine Dependence sums six items about a smoker's habits: time to the first cigarette after waking (0 to 3 points), difficulty refraining where it's forbidden (0 or 1), which cigarette would be hardest to give up (0 or 1), cigarettes smoked per day (0 to 3), smoking more heavily in the first hours after waking (0 or 1), and smoking even while ill in bed (0 or 1). The total runs from 0, no measurable dependence markers, to 10, every marker present at its strongest.
Heatherton, Kozlowski, Frecker, and Fagerström published the current six-item version in the British Journal of Addiction in 1991 as a revision of Fagerström's earlier eight-item Tolerance Questionnaire from 1978. The revision trimmed and reweighted items against how well each one tracked biochemical markers of nicotine intake, like blood cotinine and expired carbon monoxide, in the validation samples the authors studied — keeping what predicted physical dependence and dropping what didn't add much.
Two items carry more than a single point: time to first cigarette and cigarettes per day, each worth up to 3. Of those, time to first cigarette gets particular attention in the smoking-cessation literature as one of the single best individual markers of physical dependence, because it captures how urgently the body demands nicotine after the longest natural gap most smokers go through — a night's sleep. A smoker who needs a cigarette within five minutes of opening their eyes is telling you something the daily total alone won't: how fast withdrawal sets in once nicotine clears.
- Select Time to first cigarette after waking — within 5 minutes scores highest, after 60 minutes scores 0.
- Answer whether it's difficult to refrain from smoking in places where it's forbidden.
- Pick which cigarette would be hardest to give up — the first of the day, or any other.
- Select how many cigarettes are smoked per day, from 10 or fewer up to more than 30.
- Answer whether smoking happens more heavily in the first hours after waking.
- Answer whether smoking continues even when very ill and in bed most of the day, then read the total, 0 to 10.
Worked example — a score of 9 out of 10
A smoker lights up within 5 minutes of waking (3 points), finds it hard to refrain where smoking is forbidden (1), would hate most to give up that first cigarette (1), smokes 21 to 30 a day (2), smokes more heavily in the first hours awake (1), and still smokes when very ill (1): 3 + 1 + 1 + 2 + 1 + 1 = 9, landing in the 8-to-10 band most commonly labeled very high dependence.
Change only the cigarette count to more than 30 a day and every other marker stays present, and the total reaches the ceiling of 10: 3 + 1 + 1 + 3 + 1 + 1 = 10. At the opposite end, a smoker who lights up more than 60 minutes after waking, has no difficulty refraining anywhere, doesn't hate the first cigarette most, smokes 10 or fewer a day, doesn't smoke more heavily early on, and stops when ill scores 0 + 0 + 0 + 0 + 0 + 0 = 0, the floor of the scale.
Questions
Why does time to first cigarette count for up to 3 points?
Because it's considered one of the strongest single indicators of physical nicotine dependence in the smoking-cessation literature — it captures how quickly a smoker needs to top up nicotine levels after the longest gap most people go without, an overnight sleep. Lighting up within five minutes of waking signals a body that has already begun withdrawing, which is why this one item carries the same maximum weight as the entire cigarettes-per-day question.
What do Fagerström Test score bands mean?
A widely used convention reads 0 to 2 as very low dependence, 3 to 4 as low, 5 as moderate, 6 to 7 as high, and 8 to 10 as very high. This is a commonly cited scheme rather than the only one in circulation — some clinical references collapse the categories into four tiers instead of five — so the raw 0-to-10 total is the more portable number to record and compare over time.
How is this different from the original Fagerström Tolerance Questionnaire?
The 1978 Tolerance Questionnaire used eight items and a more complex scoring scheme. Fagerström and colleagues revised it in 1991, dropping two items that added little predictive value, keeping six, and adjusting the point weights to better match how well each item tracked biochemical measures of nicotine intake in their validation data. The result is the shorter, more widely used test this calculator scores.
Does a low score mean nicotine dependence isn't a concern?
Not necessarily. The test screens for physical dependence markers specifically — timing, quantity, and withdrawal-driven behavior — and doesn't capture psychological or behavioral dimensions of tobacco use, like smoking tied to stress, social settings, or habit rather than physical craving. A low total can still coexist with a smoker who finds quitting difficult for reasons this six-item instrument was never built to measure.
Who is the Fagerström Test meant to be used by?
It's a brief screening instrument used in clinical and research settings to gauge how physically dependent a smoker is on nicotine, often to help tailor cessation support such as nicotine replacement dosing. It's typically administered or interpreted by a clinician or researcher rather than used as a standalone self-diagnosis tool, since the score is meant to inform a conversation about treatment, not replace one.
Can the Fagerström Test be used for vaping or smokeless tobacco?
The original six items are worded around cigarettes specifically — count per day, timing after waking, and so on — so applying it directly to vaping or smokeless products stretches it past what it was validated for. Researchers have built adapted versions for other nicotine products, but this calculator scores the classic cigarette-based instrument as published in 1991.
