Other countries are watching Colorado, which has the world's first fully regulated recreational marijuana market. The Netherlands has legal sales of pot but does not allow growing or distribution. Uruguay's marijuana programme is still under development.
Colorado legalised pot in 2012, but commercial sale did not begin until January. Washington state sales begin in coming months.
The tax total reported by the state Department of Revenue indicates 14.02 million dollars (£8.4 million) of recreational pot was sold from 59 businesses. The state collected roughly 2.01 million dollars in taxes.
The taxes come from 12.9% sales taxes and 15% excise taxes. Including licensing fees and taxes from Colorado's pre-existing medical marijuana industry, the state collected about 3.5 million dollars (£2.1 million) from the marijuana industry in January.
By comparison, Colorado made about 2.7 million dollars (£1.6 million) in alcohol excise taxes in January last year.
Colorado tax officials say the January marijuana reports were in line with expectations.
The tax release intensified lobbying over how Colorado should spend its pot money. Budget-writers expect the nascent marijuana industry to be extremely volatile for several years, making politicians nervous about where to direct the funds.
Governor John Hickenlooper has sent the legislature a detailed 134 million dollar (£80 million) proposal for recreational and medical marijuana money, including new spending on anti-drug messaging to children and more advertising discouraging driving while high.
State police chiefs have also asked for more money.
