The PM investigators [18] reported a few minor differences in the biological activity of the rats exposed to cigarettes with the additives, but dismissed these differences as following no clear pattern, suggesting they are due to statistical inference. The overall conclusion, reported in the paper's abstract is that the data [from a 90-d inhalation study] indicate that the addition of the 333 commonly used ingredients, added to cigarettes in three groups, did not increase the inhalation toxicity of the smoke.
