Note: Quantity is modeled as a continuous variable using different estimators. Among the 30,303 smokers in the sample, only 30,289 reported their smoking quantity. Each regression controls for gender, age, age of initiation, income, education, household size, employment, health insurance, body mass, missing indicators (for income, health insurance, body mass) and province indicators. Standard errors (in parentheses) are clustered at the province level.
