【社会人文】减少尼古丁水平可有助于戒断吸烟

Addiction: Lowering Nicotine Levels May Help Cut Smoking

Published: November 20, 2007
Smokers who were given nicotine-reduced cigarettes for five weeks and then allowed to return to their regular brands ended up smoking less, according to the authors of a small study.

The study suggested that if the government required tobacco companies to lower the nicotine levels in cigarettes, more people might be able to quit and fewer might become addicted in the first place. The companies already make cigarettes marketed as low tar and low nicotine. But they do so, the researchers say, not by lowering the amount of nicotine but by engineering the cigarette so that, in theory at least, less nicotine and tar is inhaled.

“Because there is plenty of nicotine available in the tobacco of commercial low-yield cigarettes, it is easy for the smoker to alter puff rate and/or smoking intensity,” says the study, in the November issue of Cancer Epidemiology, Biomarkers and Prevention. The study was led by Dr. Neal L. Benowitz of the University of California, San Francisco.

By contrast, the cigarettes used in the study contained less nicotine. Twenty volunteers were given the cigarettes for four weeks, with the amount of nicotine in them dropping each week. Then the volunteers were told they could return to their own brands.

The researchers were mostly interested in seeing whether the smokers compensated for the reduced nicotine by smoking more or changing their style of smoking. They found that unlike with commercial low-yield cigarettes, this was not the case. “戒断吸烟”改为 “戒烟“较为合适 我来认领此篇文章,24小时内交稿 Addiction: Lowering Nicotine Levels May Help Cut Smoking

成瘾:低尼古丁含量可能有助于戒烟
作者进行了一项小群体研究,研究要求吸烟者连续5周吸入低尼古丁含量的香烟,然后换回其习惯的牌子,结果显示这些吸烟者吸烟减少了。

The study suggested that if the government required tobacco companies to lower the nicotine levels in cigarettes, more people might be able to quit and fewer might become addicted in the first place. The companies already make cigarettes marketed as low tar and low nicotine. But they do so, the researchers say, not by lowering the amount of nicotine but by engineering the cigarette so that, in theory at least, less nicotine and tar is inhaled.

这项研究提示,如果政府要求烟草公司降低香烟中的尼古丁含量,上瘾的人会减少,更多的人有可能会戒烟。烟草公司在市面上的销售的香烟一直标榜着低尼古丁和低焦油含量。但事实上,他们并不是真的通过降低尼古丁和焦油含量,而是通过改造香烟让吸烟者吸入尼古丁和焦油的量减少,这至少在理论上是成立的。

“Because there is plenty of nicotine available in the tobacco of commercial low-yield cigarettes, it is easy for the smoker to alter puff rate and/or smoking intensity,” says the study, in the November issue of Cancer Epidemiology, Biomarkers and Prevention. The study was led by Dr. Neal L. Benowitz of the University of California, San Francisco.

“癌症流行病学,生物标记与预防”十一月份刊登的一篇文章指出:“市面上出售的所谓低焦油和尼古丁含量的香烟中含有大量的尼古丁,因此,吸烟者很容易改变吸烟的频率和/或强度。”这项研究是由圣弗兰西斯科加州大学的Neal L. Benowitz博士领导完成的。

By contrast, the cigarettes used in the study contained less nicotine. Twenty volunteers were given the cigarettes for four weeks, with the amount of nicotine in them dropping each week. Then the volunteers were told they could return to their own brands.

与之相反,研究中所用的香烟尼古丁含量比较低。20个志愿者被要求吸入低尼古丁含量的香烟4周,测试表明他们体内的尼古丁含量每周都在下降。4周之后,这些志愿者被告知可以换回之前习惯牌子的香烟。

The researchers were mostly interested in seeing whether the smokers compensated for the reduced nicotine by smoking more or changing their style of smoking. They found that unlike with commercial low-yield cigarettes, this was not the case.

研究者们最感兴趣的是观察吸烟者在吸入低尼古丁含量香烟的时候,是否会通过吸得更多或者改变吸烟习惯以代偿这一变化。研究者们发现,与市面销售的香烟不同,参与试验的志愿者并未表出代偿性的改变。 成瘾:低尼古丁含量可能有助于戒烟
