“These smokers have higher levels of nicotine and possibly other tobacco toxins in their body, and they may be more addicted than smokers who refrain from smoking for a half hour or more,” said Dr. Muscat. "It may be a combination of genetic and personal factors that cause a higher dependence to nicotine.”

Tobacco use causes about 90 percent of lung cancer death in men and 80 percent in women. Tobacco use is attributed to many other types of cancer as well, including mouth, throat and tongue cancers, pharynx, larynx, esophagus, bladder, stomach, cervix, kidney and pancreatic cancers, and acute myeloid leukemia.

A 2011 National Research Council report shows the U.S. life expectancy is now lower than most every other industrialized country and cigarette smoking is to blame. While smoking rates among Americans continue to decline—now 23.5 percent for men and 17.9 percent for women, according to the Centers for Disease Control and Prevention— the number of people who smoked during the mid-1950s was around 57 percent. The impact of smoking several decades ago is reflected by our current life expectancy rate, the council report says.
