This paper was written in response to a request from the U.S. National Cancer Institute. The goal is to discuss some research directions related to establishing tobacco product standards under the Family Smoking Prevention and Tobacco Control Act, which empowers the U.S. Food and Drug Administration to regulate tobacco products. Potential research related to tobacco product ingredients, nicotine, and harmful or potentially harmful constituents of tobacco products is discussed.
Ingredients, which are additives, require less attention than nicotine and harmful or potentially harmful constituents. With respect to nicotine, the threshold level in tobacco products below which dependent users will be able to freely stop using the product if they choose to do so is a very important question. Harmful and potentially harmful constituents include various toxicants and carcinogens. An updated list of 72 carcinogens in cigarette smoke is presented. A crucial question is the appropriate levels of toxicants and carcinogens in tobacco products. The use of carcinogen and toxicant biomarkers to determine these levels is discussed.
The need to establish regulatory standards for added ingredients, nicotine, and other tobacco and tobacco smoke constituents leads to many interesting and potentially highly significant research questions, which urgently need to be addressed.
本文是应美国国家癌症研究所的要求撰写的。目的是讨论与《家庭吸烟预防和烟草控制法案》下建立烟草制品标准相关的一些研究方向,该法案授权美国食品和药物管理局监管烟草制品。本文讨论了与烟草制品成分、尼古丁以及烟草制品中有害或潜在有害成分相关的潜在研究。
成分(即添加剂)比尼古丁和有害或潜在有害成分受到的关注更少。关于尼古丁,烟草制品中低于此阈值的水平,如果依赖性使用者选择这样做,他们将能够自由停止使用该产品,这是一个非常重要的问题。有害和潜在有害成分包括各种毒物和致癌物。本文提出了香烟烟雾中 72 种致癌物的最新清单。一个关键问题是烟草制品中有毒物质和致癌物的适当水平。本文讨论了使用致癌物和毒物生物标志物来确定这些水平的问题。
需要为添加成分、尼古丁以及其他烟草和烟草烟雾成分制定监管标准,这导致了许多有趣且潜在非常重要的研究问题,这些问题急需解决。
