Note: Standard errors clustered at the household level in parenthesis. Regression also included controls for age, gender, household size, place of living, education, income group and number of hours of exercise. These are not shown in the table. Reference group: non-users (DoC = 0, NL = 0 and Both = 0) and year = 2013. *** p < 0.01, ** p < 0.05, and * p < 0.1.
