According to tobacco regulations, nicotine and tar contents must be stated on cigarette packets. But since there is no satisfactory measuring method for analyzing the values of nicotine and tar in cigar smoke, there is no corresponding demand on cigars and cigarillos. The reason that no standard measuring method has been found is that the products are available in many various forms and sizes and neither government officials nor the industry has been able to produce a model that works for all product versions.
However, values stated on cigarette packets do not measure the actual content in the cigarettes themselves but the values produced during smoking, which is measured in a standard smoke machine.
