↵Analysis from smoking histories from the 1978, 1979, 1980, 1987, 1988, 1992, 1995, 1997, 1998, 1999, and 2000 National Health Interview Surveys for individuals age 25 and older at the time of the survey. Smoking histories are reconstructed using the age at smoking initiation and cessation. See also Note 5. Additional controls include age, gender, year of birth, race, and survey year dummies. Robust standard errors in square brackets. ***, **, * denote statistical significance at the 1 percent, 5 percent, and 10 percent confidence levels, respectively.
