NEW YORK (MainStreet) — The Continental Divide is more than a state tourist attraction; it describes the attitude Colorado voters have for the recent legalization of recreational marijuana. More than half (51%) of the citizens of Colorado say retail pot has been bad for the state's image. But the younger the respondent, the more favorable they are, according to a new Quinnipiac University poll. Most voters (57%) 18 to 29 years old say it's good for the state's image, while voters over 65 years old (67%) say it's bad for Colorado.

And yet, one in ten Coloradans say they've tried marijuana since it became legal January 1, and 51% say they've smoked grass at some point in their life. Even among the naysayers, voters over 65 years old, more than one quarter (26%) say they have partaken of pot.

Pot popularity falls along party lines. Fully 73% of Republicans and 56% of independent voters say legalization is bad for the state's image, but 57% of Democrats believe it's a boost for Colorado.

"Coloradans don't mind if their neighbors grow a little grass in their living room, but the prospect of big time grow houses next door is a turnoff," says Tim Malloy, assistant director of the Quinnipiac University Polling Institute. "And they say thanks but no thanks to marijuana brownies."

Nearly three quarters (73%) of poll respondents say it wouldn't bother them if a neighbor grew marijuana at home – and even the more conservative voters over 65 agree (56%). Still, a large majority -- more than 80% -- say they oppose changing the law to allow people to grow more than 12 marijuana plants in their home.

Only 17% of Colorado voters say it is "very likely" or "somewhat likely" they would try marijuana brownies if someone brought them to a gathering, while 12% say it is "somewhat unlikely." Most (70%), say it is "very unlikely" they would try the pot-laced sweet treats.

And nearly two thirds (64%) say they would be "very uncomfortable" riding in a car with a driver who has smoked or consumed moderate amounts of marijuana, while 17% would be "somewhat uncomfortable."
