DENVER - A group behind the initiative, passed by voters, legalizing small amounts of marijuana in Denver, announced plans Wednesday to take the issue statewide in 2006.
SAFER, Safer Alternatives For Enjoyable Recreation, announced it will start a signature campaign to try and get the issue on the state ballot.
If passed, the measure would legalize the possession of one ounce or less of marijuana for people 21 years or older.
Alaska and Nevada have both voted down similar initiatives in recent years.
"If this initiative passes, it's not going to be a free-for-all around Colorado in terms of marijuana possession," said Mason Tvert, executive director of SAFER. "All this will do is allow those cities and towns which enjoy home rule status -- which accounts for about 90 percent of the population -- to set their own policies."
Tvert planned to make the announcement for the new campaign near the state Capitol steps Wednesday morning, but was asked to leave by a state trooper because he didn't have a permit.
He moved to the sidewalk, where he said his group would work to mobilize students around Colorado to gather signatures and campaign for the change in the law.
To get the measure on the ballot, the group will have to collect about 68,000 signatures.
And then, they'll have to convince voters to approve it against the advice of powerful opponents, including Gov. Bill Owens, whose spokesman told 9News the governor will oppose the measure.
Since Initiative 100 passed last November, Denver Police have continued to make marijuana arrests under state law.
