烟草依赖仍然是全世界过早发病和死亡的主要可预防原因之一。烟草和烟草烟雾中存在超过 8,000 种化合物，但我们不知道其中许多对吸烟者有什么影响（如果有的话）。主要兴趣是尼古丁，以及有毒和致癌作用，并且已经阐明了烟草烟雾的几种主要和次要成分，这些成分负责吸烟对健康的负面影响。吸烟者自己报告了吸烟带来的各种积极影响，包括对抑郁、焦虑和精神敏锐度的影响。吸烟也被证明对帕金森病有保护作用。是否有关于因尼古丁而吸烟的积极影响的主观报告，烟草烟雾的某些其他成分，还是它们是吸烟提供的尼古丁戒断症状缓解的表现？这篇小型综述总结了目前已知的烟草烟雾成分可能对吸烟者产生积极影响的情况。

Tobacco dependence remains one of the major preventable causes of premature morbidity and mortality worldwide. There are well over 8,000 compounds present in tobacco and tobacco smoke, but we do not know what effect, if any, many of them have on smokers. Major interest has been on nicotine, as well as on toxic and carcinogenic effects and several major and minor components of tobacco smoke responsible for the negative health effects of smoking have been elucidated. Smokers themselves report a variety of positive effects from smoking, including effects on depression, anxiety and mental acuity. Smoking has also been shown to have protective effects in Parkinson’s Disease. Are the subjective reports of a positive effect of smoking due to nicotine, of some other components of tobacco smoke, or are they a manifestation of the relief from nicotine withdrawal symptoms that smoking provides? This mini-review summarises what is currently known about the components of tobacco smoke with potential to have positive effects on smokers.
