Flavouring and other additives increase cigarettes’ addictiveness

US: Ingredients that help enhance the appeal of “light” and “low-tar” cigarettes may contribute to the addictiveness of smoking, a study suggests.

Researchers scoured more than 7 million tobacco industry documents to see how additives known as pyrazines were being used and found these ingredients were introduced after consumers in the 1960s rejected the first “low-tar” cigarettes as being flavorless.
