Pick a quit date and stop smoking on that day — don’t taper gradually
定一个戒烟日,到那天一次停掉,别先慢慢减
No cost at all. Just choose a date on the calendar and let family and coworkers know in advance.
Many people try to cut back a little each day until they reach zero. Yet after six months, only 15.5% of those who gradually reduced their intake stayed smoke‑free, compared with 22% of people who set a quit date and stopped all at once. So it’s better to pick a date and quit completely on that day.

4. Pick a quit date and stop smoking on that day — don’t taper gradually
Cost: No cost at all. Just choose a date on the calendar and let family and coworkers know in advance.
In plain terms: Many people try to cut back a little each day until they reach zero. Yet after six months, only 15.5% of those who gradually reduced their intake stayed smoke‑free, compared with 22% of people who set a quit date and stopped all at once. So it’s better to pick a date and quit completely on that day.
Benefit: In the UK, 697 smokers were randomly assigned to two groups. One group quit on a predetermined date; the other cut their cigarette use by 75% during the two weeks before that date. Both groups received nursing support and used nicotine replacement therapy around the quit date. At four weeks, 49.0% (95% CI 43.8–54.2) of the “quit‑on‑date” group remained smoke‑free, versus 39.2% (34.0–44.4) of the “taper‑first” group; the relative risk was 0.80 (0.66–0.93). By six months, 22.0% (18.0–26.6) of the quit‑on‑date group stayed quit, compared with 15.5% (12.0–19.7) of the taper‑first group; the relative risk was 0.71 (0.46–0.91). Even among people who preferred tapering, the quit‑on‑date approach yielded higher success rates at four weeks (52.2% vs. 38.3%).

Notes: This is a somewhat controversial topic. Cochrane previously published a review comparing these two methods; it concluded they performed similarly (RR 0.94, 95% CI 0.79–1.13, based on 10 trials with 3,760 participants). However, that review was withdrawn in 2019 and is no longer updated. The best current evidence comes from the trial described above, which favors quitting on a set date. Both groups in that trial also used nicotine replacement therapy before the quit date, an approach itself backed by evidence: early use raises success rates by roughly 25% (RR 1.25, 95% CI 1.08–1.44, based on 9 trials with 4,395 participants; moderate‑certainty evidence). Therefore, the recommended strategy is to pick a quit date, start nicotine replacement therapy two weeks beforehand, and then quit all at once on that day.

4. 定一个戒烟日,到那天一次停掉,别先慢慢减
成本: 不花钱。就是在日历上挑一天,提前告诉家里人和同事。
说人话: 很多人打算先每天少抽几根,慢慢减到零。可到了第六个月,定好日子一次停掉的人里 22% 没再抽,慢慢减的只有 15.5%。所以定一个日子,到那天一次停掉。
收益: 英国 697 名吸烟者随机分成两组。一组在戒烟日当天一次停掉,一组在戒烟日前两周先把烟量减掉 75%。两组都有护士的行为支持,戒烟日前后都用尼古丁替代品。第 4 周时,一次停那组 49.0%(95% CI 43.8–54.2,这是可信范围)没复吸,慢慢减那组 39.2%(34.0–44.4),相对风险比 0.80(0.66–0.93)。到第 6 个月,一次停那组 22.0%(18.0–26.6),慢慢减那组 15.5%(12.0–19.7),相对风险比 0.71(0.46–0.91)。原本就偏好慢慢减的人,第 4 周的成功率也低于偏好一次停的人(38.3% 对 52.2%)。

备注: 争议。Cochrane 原先有一篇专门比这两种办法的综述,结论是两者差不多(RR 0.94,95% CI 0.79–1.13,10 项试验、3760 人),但那篇已于 2019 年撤回、不再更新。所以眼下最好的证据是上面这项随机试验,方向支持一次停。另外那项试验里两组都在戒烟日之前就开始用尼古丁替代品,这个做法本身也有证据:提前用比戒烟日当天才开始,成功率高约 25%(RR 1.25,95% CI 1.08–1.44,9 项试验、4395 人,中等确定性证据)。所以合理的排法是先定日子,提前两周贴上,到日子一次停。
