Hi, guys! A smoker here. Does anyone heard about using a zeolite in cigarettes/cigarette filters? Recently heard about studies of reducing the harmful ingredients in cigarettes by adding zeolite. Is this alredy a thing, and does any brand use it? Also what do you think about it? I looked up some researches myself, but it will be nice to get some more information. Please keep the "kys"s and "faggot"s to the reasonable minimum.
