Analyses of the smoke from cigarettes made from borate-treated tobacco have shown a significant increase in the levels of phenol, o-cresol, m-, p-cresol, and benzo[a]pyrene.

The profile for untreated tobacco indicates that there are two distinct modes of phenol formation. Addition of borate to the tobacco suppresses phenol formation at lower temperatures and greatly enhances its formation at higher temperatures. The modes of formation of the cresols do not appear to be markedly altered by the addition of borate to tobacco.
