In a separate two-year study, published in the journal Addiction, reducing the level of nicotine in cigarettes was not shown to help people quit the habit.

《瘾癖》杂志发表了一项耗时两年的研究，该研究表明减少香烟中尼古丁含量并不能帮助烟民戒烟。

Researchers recruited 135 smokers who were not interested in quitting, asking some to smoke cigarettes they were given and the rest to continue smoking their regular brand.

研究人员找来了135个没有戒烟念头的烟民，他们中一些人吸指定的烟，剩下的继续吸自己平时吸的烟。

Those in the experimental group were given cigarettes with progressively less nicotine in them over the course of 6 months, and then were asked to smoke the free, lower-nicotine cigarettes for 6 months.

在半年时间里，实验组中吸烟者拿到的香烟中的尼古丁含量是逐渐减少的。之后半年，他们吸不含或含有少量尼古丁的烟。

Participants were followed for another year after the 6 months of low-nicotine cigarettes. Researchers found that almost none of the 153 people -- who had not been interested in quitting in the first place -- had reduced or quit their smoking.

半年内只吸含有少量尼古丁烟的参与者又被追踪观察了一年。研究者发现这153个没有戒烟念头的烟民几乎无人减少了吸烟量或已戒烟。
