The estimated annual health care costs of smoking/obesity are a combination of junk science and junk economics — i.e., if you smoke and you get sick or die, then your sickness/death is assumed to be entirely attributable to your smoking. Moreover, end of life costs add up for virtually everyone.
“Annual health care costs are roughly $96 billion for smokers and $147 billion for the obese, the government says. These costs accompany sometimes heroic attempts to prolong lives, including surgery, chemotherapy and other measures. But despite these rescue attempts, smokers tend to die 10 years earlier on average, and the obese die five to 12 years prematurely, according to various researchers’ estimates.” [Associated Press]
