Marijuana regulators who are considering how the drug should be taxed, sold and regulated in Colorado are facing a deadline to get their ideas to state officials.

A marijuana task force plans its final meeting Thursday. The task force is giving a lengthy set of recommendations to state lawmakers and the governor’s office.

The marijuana task force has several questions still to work out. One big question is how to tax the newly legal drug. Voters wanted excise taxes to go to school construction, but pot taxes will also have to pay for safety enforcement and drug education measures. Estimates vary widely on how large the marijuana market will be.

Only Colorado and Washington have legalized pot.
