Lawmakers open door to repeal Colo. marijuana law

DENVER Recreational marijuana in Colorado appeared to be in serious trouble Monday night, when a bipartisan group of state senators advanced a plan to open the door to possible repeal of retail pot legalization.

The late-night repeal effort came on the final possible day for the legislation to get a vote by the full Senate. Lawmakers conclude work for the year on Wednesday.

• Colorado court: Pot smokers can still get fired
• Colorado's Amendment 64 legalizes recreational marijuana use
• Legal pot luring tens of thousands to Colo., Wash., for "national stoner holiday"

If approved, the measure would ask voters this fall whether retail pot sales should be repealed without an accompanying vote to tax pot above 30 percent.

The repeal possibility came after the Senate gave initial approval to a marijuana blood-limit standard that senators have rejected several times before, including twice this year.

Marijuana uncertainty reigned as the Legislature entered its final hours. Separate regulation rules and tax rates awaited Senate votes Monday evening.
