The filters in your cigarettes may contain pig’s blood. Thats what I just read on the net, that Researches have confirmed pig haemoglobin, which is a blood protein, have been found in the filters. It’s being used in the filters to somehow reduce harmful chemicals from entering your lungs.
So far only one tobacco manufacturer in Greece confirmed the use of pig haemoglobin. Researchers have been demanding more transparency in what goes into making a cigarette, coz it may be a big deal for certain groups of people like Muslims, Jews and Vegetarians, but tobacco manufacturers aren’t too eager to share their secrets “that’s our business and a trade secret.”
