http://www.canorml.org/background/CA_legalization2.html- California NORML estimates that a legally regulated market for marijuana could yield the state at least $1.2 billion in tax revenues and reduced enforcement costs.
- Based on experience with the cigarette tax, total revenues of $1.5 - $2.5 billion might ultiimately be realized.
- Based on experience with the wine industry, the total economic activity generated by legal marijuana could be nearly four times as great as retail sales, around $12 - $18 billion. Amsterdam-style coffeehouses would generate jobs and tourism. If the marijuana industry were just one-third the size of the wine industry, it would generate 50,000 jobs and $1.4 billion in wages, along with additional income and business tax revenues for the state.

http://www.prohibitioncosts.org/mironreport.html- The report estimates that legalizing marijuana would save $7.7 billion per year in government expenditure on enforcement of prohibition. $5.3 billion of this savings would accrue to state and local governments, while $2.4 billion would accrue to the federal government.
- The report also estimates that marijuana legalization would yield tax revenue of $2.4 billion annually if marijuana were taxed like all other goods and $6.2 billion annually if marijuana were taxed at rates comparable to those on alcohol and tobacco.
