Cigarette Filters
Most consumers perceive filtered cigarettes as safer than non-filtered cigarettes. Filters dominated the market by the 1960s and filter cigarettes’ market share climbed from 0.5% in 1950 to more than 98% today. Filter manipulation has been instrumental creating lights and ultra light cigarettes.

1976 Filtration: More Nicotine and Tar
“In most cases, however, the smoker of a filter cigarette was getting as much or more nicotine and tar as he would have gotten from a regular cigarette. He had abandoned the regular cigarette, however, on the grounds of reduced risk to health.”
Ventilation and Lung Cancer
Since the rise in popularity of “low-tar” and ventilated brands that are particularly easy to inhale, the location of lung cancer has moved outward toward the lung’s periphery. Adenocarcinoma is a common tumor in that location compared to small cell and squamous cell tumors that occur in the center of the lungs.
