DENVER – A new NBC News-Wall Street Journal poll finds a majority of Americans support legislative efforts to legalize marijuana.

Fifty-five percent say they would support laws in which adults 21 and older are allowed to buy limited amounts of marijuana for personal use.

About a quarter would not approve of legalizing marijuana, but they wouldn’t actively oppose it either. Nineteen percent would actively work to oppose and overturn any legalization efforts.

There is no question that marijuana has changed Colorado’s image. Whether that’s for the better or worse is still up for debate.

“To the extent that the cannabis industry has changed Colorado. I think Colorado has even more changed the image of cannabis industry.
