Both the Tobacco Control Act in the U.S. and Article 9 of the Framework Convention on Tobacco Control enable governments to directly address the addictiveness of combustible tobacco by reducing nicotine through product standards. Although nicotine may have some harmful effects, the detrimental health effects of smoked tobacco are primarily due to non-nicotine constituents. Hence, the health effects of nicotine reduction would likely be determined by changes in behavior that result in changes in smoke exposure.
Herein, we review the current evidence on nicotine reduction and discuss some of the challenges in establishing the empirical basis for regulatory decisions.
To date, research suggests that very low nicotine content cigarettes produce a desirable set of outcomes, including reduced exposure to nicotine, reduced smoking, and reduced dependence, without significant safety concerns. However, much is still unknown, including the effects of gradual versus abrupt changes in nicotine content, effects in vulnerable populations, and impact on youth.
A coordinated effort must be made to provide the best possible scientific basis for regulatory decisions. The outcome of this effort may provide the foundation for a novel approach to tobacco control that dramatically reduces the devastating health consequences of smoked tobacco.
美国的《烟草控制法案》和《烟草控制框架公约》第9条都使各国政府能够通过产品标准降低尼古丁含量,从而直接解决可燃烟草的成瘾性问题。尽管尼古丁可能有一些有害影响,但吸烟对健康的有害影响主要归因于非尼古丁成分。因此,降低尼古丁对健康的影响可能取决于行为变化导致的烟雾暴露变化。
在此,我们回顾了当前关于降低尼古丁含量的证据,并讨论了为监管决策建立实证基础时面临的一些挑战。
迄今为止,研究表明尼古丁含量极低的香烟会产生一系列理想的结果,包括减少尼古丁暴露、减少吸烟和降低依赖性,且不存在重大安全问题。然而,仍有许多未知之处,包括尼古丁含量逐渐变化与突然变化的影响、对弱势群体的影响以及对青少年的影响。
必须做出协调一致的努力,为监管决策提供尽可能最佳的科学依据。这一努力的成果可能为一种全新的烟草控制方法奠定基础,从而大幅减少吸烟对健康造成的毁灭性后果。
