For the individual level analysis, I use data from the Behavioral Risk Factor Surveillance System from 2006-2016. I find an increase of about 0.5% in the number of daily smokers in legalized states in comparison to non legalized states. There is no significant change in alcohol consumption. At the state level, I gather data from 27 state-level Department of Revenues since 2006 and find that cigarette tax revenue dropped by $19.2 million. The estimates are statistically significant at the 10% level. Furthermore, alcohol tax revenue dropped by $18.4 million, but the estimates are not statistically significant. However, an estimated per dollar exchange of $1 of marijuana revenue for 58 cents of alcohol revenue is found and the estimates are statistically significant at the 1% level.enResearch Paper
