Washington (CNN) -- Last year, voters in Colorado approved legalizing recreational marijuana, and on Tuesday night, they resoundingly supported taxing it.
With nearly all votes counted, 65% supported the new tax, while 35% opposed it. The measure would impose a special 15% excise tax on marijuana to help fund school construction, along with a 10% sales tax to bolster marijuana-related law enforcement efforts.
The passage was widely expected, despite opponents arguing it's unfair to single out marijuana for higher taxation than products such as beer.
Strong support for the measure is pegged largely to the money it is expected to bring in. The nonpartisan Colorado Legislative Council projects that the measure will generate nearly $70 million in additional state tax revenue next year.
However, a kindergarten-through-12th-grade school-finance overhaul was rejected; it would have increased income taxes about $1 billion a year and revived a progressive income tax structure abandoned in the 1980s.
