Set a quit date and stop completely that day instead of first cutting down
Gradually reducing a few cigarettes each day feels appealing. But at six months in the cited trial, 22% of people assigned to stop all at once remained abstinent, versus 15.5% assigned to taper. Set a date and stop that day.
What it takes
Free. Choose a calendar date and tell family and coworkers beforehand.
What you may gain
A UK trial randomized 697 smokers to abrupt cessation or a 75% reduction during the two weeks before their quit date. Both groups received nurse-led behavioral support and nicotine replacement before and after that date. At week 4, abstinence was 49.0% (95% CI 43.8–54.2) with abrupt cessation versus 39.2% (34.0–44.4) with reduction: RR 0.80 (0.66–0.93). At six months, rates were 22.0% (18.0–26.6) versus 15.5% (12.0–19.7): RR 0.71 (0.46–0.91). People who initially preferred tapering also had lower week-4 success than those preferring abrupt cessation, 38.3% versus 52.2%.
Context & considerations
The source notes disagreement: an earlier Cochrane review found little difference (RR 0.94, 95% CI 0.79–1.13; 10 trials, 3,760 people), but was withdrawn in 2019 and no longer updated. It therefore treats the trial above as the best current evidence, favoring abrupt cessation. Both trial groups began nicotine replacement before the quit date. Separately, preloading improved success by about 25% compared with starting on the quit date (RR 1.25, 95% CI 1.08–1.44; 9 trials, 4,395 people; moderate-certainty evidence). The suggested sequence is to set a date, begin a patch two weeks beforehand, and stop smoking completely on that day.
