Cocoa powder added as tobacco flavorant would not significantly increase the phenol yield of smoke, but may affect the higher fatty acid content. 

In the NCI study of the third set of experimental cigarettes (1332), the cigarette MSS composition and biological properties (mouse skin-painting studies) of four cigarette samples were compared. These included three samples to each of which had been added individually a specified amount of glycerol (Code No. 80), sugar (Code No. 81), and cocoa (Code No. 82).
