In response to increasing evidence implicating cigarette smoking as a cause of lung cancer in the 1950s, tobacco manufacturers introduced filtered and “lower-tar” cigarettes to allay consumer concerns, knowing they did not actually reduce health risks. Puncturing ventilation holes of varying sizes and numbers into the filter to dilute inhaled smoke became the optimum way to reduce tar yield.1
Despite these changes, smoking remains responsible for 80% to 90% of lung cancer diagnoses and 5-year survival is 18%, highlighting the importance of prevention.2 Lung cancer screening with low-dose computed tomography has been shown to improve mortality, and tobacco treatment is a required component of effective screening. We investigated the association of filter status, tar level, and menthol flavor with lung cancer outcomes in the National Lung Screening Trial.
That's interesting but I suppose not surprising. What did surprise me though is the fact light cigarettes were targeted at people wanting to quit smoking, marketing it as an alternative to quitting. Wow.
All a clever marketing ploy to keep the addiction going, the amount of nicotine in them the same just maybe a lower tar level. They are constantly trying to keep their business model alive and working. See my next post.
