Tobacco and cigarette giving decreased sub-current smoke

摘要

Tobacco preferably contains powdery basic calcium phosphate, particularly, powdery calcium-defective basic calcium phosphate, adsorbed on or mixed with the tobacco, for decreasing the amount of side stream smoke rising from the burning site. In the case that tobacco is used in the form of a cigarette, the paper sheet surrounding the tobacco may contain powdery basic calcium phosphate.
