(CNN) - Slightly more Colorado voters support the state's new recreational marijuana law now than six months ago, according to a new Quinnipiac University survey.
The new poll also indicates that a slim majority consider the law as harmful to the state's image.
Ticking upwards in support
Fifty-eight percent of voters support the legalization of pot, up from 54% in August, the poll shows. The selling of marijuana became legal on January 1.
The four percentage point margin falls within the survey's sampling error.
Breaking the numbers down by demographics, 39% of Republicans support the new law, while 76% of Democrats and 55% of independents favor it.
The law is much more popular among those in the 18-29 age bloc, with 78% in support. The number drops as the age gets older. Only 33% of those 65 or older support the law.
Clouding the state's image?
While support seems to be trending upwards, a majority of Colorado voters, 51%, say the new law is bad for the state's image, compared to 38% who disagree and 10% who are unsure or don't have an opinion.
Another bare majority, 51%, say they have tried marijuana previously, but only 10% say they have used marijuana since it became legal last month.
Current law allows Coloradans to grow up to a dozen marijuana plants in their homes. More than seven in 10 say they wouldn't be bothered if one of their neighbors was growing marijuana.
Only 17% say it is very or somewhat likely they would try marijuana brownies at a gathering. Eighty-one percent would be somewhat or very uncomfortable riding in a car with a driver who's had moderate amounts of marijuana
Quinnipiac interviewed 1,139 registered voters in Colorado by telephone from January 29 to February 2. The overall sampling error is plus or minus 2.9 percentage points.
