提到戒煙，有的人說應該一下子戒掉，有的人則贊成一點點戒。到底哪種方法更有效？英國牛津大學一項最新研究顯示，“快斷法”更為有效，比“慢斷法”的成功率高出25%。

It is a question that prompts much debate - what is the best way for a smoker to quit?
到底什么是最佳戒煙方式？人們對這一問題一直存在爭議。

Some people advocate the method of cutting down gradually to a point where you no longer need and desire the nicotine hit.
一些人提倡“慢斷法”，認為要一點點戒。

But, a new study has today quashed that theory, instead offering evidence that suggests the best way to give up is to go cold turkey.
而一項最新研究推翻了這一說法。研究顯示，“快斷法”更為有效。

Scientists confirmed that smokers who try to kick their habit bit by bit are less likely to succeed than those with the willpower to give it up in one go.
科學家認為，對戒煙者來說，“快斷法”更為有效，比“慢斷法”的成功率高。

"Cold turkey" describes the actions of a person who abruptly gives up a habit or addiction rather than gradually easing the process through gradual reduction or by using replacement medication.
Cold turkey指一個人短時間內很快戒除了某個習慣或者成癮的嗜好，而不是通過逐漸減量或使用替代藥物等手段逐漸戒除。

比如：

He quit heavy drinking cold turkey.
他沒靠任何幫助，斷然戒掉了酗酒的惡習。

熱門美劇《國土安全》第3季中，Brody被Saul的手下發現時已有毒癮，來看他們的對話：

-The guy’s a junkie, sir.
這家伙有毒癮。

-Has to be cold turkey. Where he’s going, we need him functional.
必須完全戒掉，無論如何都得讓他正常起來。
