DENVER (AP) -- Marijuana legalization could be going back to the ballot in Colorado.
State lawmakers are mulling a bill to tax the newly legal drug more than 30 percent. Some lawmakers want to add a caveat to the tax proposal -- that recreational pot won't be legal anymore unless voters approve the taxes this fall.
The discussions have pot legalization backers furious that legalization could be repealed.
But some lawmakers say voters legalized pot only because of the tax revenue it could produce, and that pot shouldn't be legal if it isn't heavily taxed.
The state House was planning a debate Friday on the tax ballot question, plus a list of proposed marijuana regulations detailing how the drug should be grown, packaged and sold.
