While cigarette smoking continues to decline in Colorado, addiction to tobacco continues to plague certain groups more than others, according to the 2012 Attitudes and Behaviors Survey on Health recently released by the Colorado Department of Public Health and Environment. The report shows cigarette smoking in Colorado fell from 19.1 percent in 2008 to 17.2 percent in 2012. It shows a decrease in the percentage of daily smokers and the number of cigarettes smoked. More Coloradans are opting for smoke-free homes and cars as well, though low-income families are less likely to have smoke-free home rules. Tobacco use remains the leading cause of preventable death and disease in Colorado, killing more than 4,400 Coloradans and costing the state nearly $2 billion in health care and more than $1 billion in lost productivity each year.
