Quantified human smoking behavior among various disease categories.

The present study reports the various quantified aspects of smoking behavior among patients (N = 244) with seven primary diagnostic categories; namely, neoplasms, endocrine, blood, circulation, respiratory, digestive, and GU. The study results indicate that patients with neoplasms and respiratory patients had longer puff durations than those in the other diagnostic categories. Patients with circulatory problems took longer to smoke a cigarette than patients with other diseases. Furthermore, patients with neoplasms tended to have higher tar delivery per cigarette than patients with other diseases. Finally, endocrine patients had the highest level of nicotine delivery per cigarette, with neoplasms and respiratory patients at the lowest level. These findings suggest a need for quantifying smoking behavior among patients of different disease categories in further studies.
