Unlit cigarette pressure drop mm water gauge 54.0
Blend nicotine (dry weight basis) % 3.25
Total sugar (dry weight basis) % 14.5
N-nitrosonornicotine (NNN) ng/gram of tobacco 97
4-(N-methylnitroso amino)-1-(3-pyridinyl)-1-butanone (NNK) ng/gram of tobacco 43
N-nitrosoanabasine (NAB) ng/gram of tobacco 12
N-nitrosoanatabine (NAT) ng/gram of tobacco 151

  1. *The filter was removed from the tobacco rod for the heating experiments.
  2. **Coresta unit is defined by the flow of air (cm3 min−1) passing through 1 cm2 surface of the paper at a measuring pressure of 1.00 kPa (cm3 min−1 cm−2 at 1kPa).
  3. ***NFDPM stands for “nicotine-free-dry-particulate-matter”; a convention used to compare yields made from machine-smoked cigarettes.
