The Centers for Disease Control and Prevention (CDC) reported a modest but
statistically significant decrease in the number of US cigarette smokers. The
new analysis involved self-reported data generated by the 2000 National
Interview Survey sample adult core questionnaire and cancer control module. The
report found that about 23.3% of adults are current smokers vs 25.0% in 1993.
Seventy percent of adult smokers said they wanted to quit, and 41% had tried to
quite at least once.
