The use of smokeless tobacco (moist snuff and chewing tobacco) can cause oral cancer and precancerous oral lesions (leukoplakia) and is a risk factor for cardiovascular diseases and nicotine addiction. Despite these adverse effects, smokeless tobacco is used commonly in the United States by young people, especially male high school students. Officials in Florida requested CDC assistance in analyzing six moist snuff products to measure three factors that affect their nicotine dose: pH, nicotine content, and moisture content. This report summarizes the results of the analysis, which indicate that the pH, amount of nicotine, and moisture vary widely among brands.
使用无烟烟草（湿鼻烟和嚼烟）会导致口腔癌和口腔癌前病变（白斑），并且是心血管疾病和尼古丁成瘾的一个风险因素。尽管有这些不良影响，但在美国，年轻人，尤其是男性高中生，却普遍使用无烟烟草。佛罗里达州的官员请求美国疾病控制与预防中心协助分析六种湿鼻烟产品，以测量影响其尼古丁剂量的三个因素：pH值、尼古丁含量和水分含量。本报告总结了分析结果，结果表明不同品牌产品的pH值、尼古丁含量和水分含量差异很大。
