摘要：Over 40% of all US smokers have comorbid alcohol, drug, or mental disorders. Using data from the 2000–2001 Healthcare for Communities survey, we conducted multivariate logistic regressions to examine these individuals' sensitivity to cigarette prices. We found that a 10% increase in cigarette prices was associated with 18.2% less smoking participation among individuals with alcohol, drug, or mental disorders, except those with alcohol dependence. Increasing cigarette taxes could be effective in reducing smoking among individuals with alcohol, drug, or mental disorders. Over 40% of all US smokers have comorbid alcohol, drug, or mental disorders. 1 Individuals in this group have a higher smoking prevalence 1 – 6 and are more likely to be heavy smokers 1 than are those without such disorders. Determining this group's sensitivity to cigarette prices 1 is important for tobacco control policy. The only prior study of this issue, 7 which used data from 1991, found that individuals with mental illness during the past year had a price elasticity of cigarette smoking participation of −0.533, compared with −0.731 for the overall population. However, this study did not examine individuals with comorbid alcohol or drug disorders. We examined smoking participation and sensitivity to cigarette prices among individuals with comorbid alcohol, drug, or mental disorders.
