In TTFC assessment, severe tobacco use is defined as tobacco use within how many minutes after waking?

<5mins

Time to first cigarette (TTFC) is a measure of nicotine dependence. The shorter the TTFC, the higher the dependence. Smoking within five minutes of waking reflects the strongest morning craving and is classified as severe dependence. The other intervals indicate progressively lower dependence: five to fifteen minutes is high but less severe, thirty to sixty minutes is lower, and more than sixty minutes shows the least morning dependence.
