Tobacco products are a range of commercially available items that have nicotine-containing tobacco as their sole or primary ingredient. In addition to cigarettes, common examples of these products include cigars, pipe tobacco and forms of smokeless tobacco such as chewing tobacco and snuff. Each year, a federally sponsored project called the National Survey on Drug Use and Health compiles information related to tobacco use in all American teenagers and adults. This information includes the number of people who initiate tobacco intake in any given 12-month time period.
