The new knowledge generated by the researches change our way of life and our culture as well. A clear example of that is the association between the smoking habit and the lung cancer, identified in 1965 by Professor Austin Bradford Hill. Along all these years, our society has incorporated such knowledge to its common sense, changing the way we think and the way we behave.
Nowadays the cigar advertisements are regulated and smoking is forbidden in public spaces. There are many benefits brought by this behavioral change to our society: reduced incidence of heart attacks, cerebral vascular accidents (CVAs) and diseases associated to exposure to passive smoking among children.
