Legal marijuana is giving Colorado a stinky conundrum. Visitors can buy the drug, but they can't use it public. Or a rental car. Or most hotel rooms.

Some legalization advocates believe they have a solution — pot clubs. Denver voters may consider a ballot measure this fall to make the city the most populous place in the nation to expressly allow pot clubs.

But marijuana clubs have proven a harder sell here than legalizing the drug in the first place. Colorado's constitution doesn't allow nor ban public use. The result is a patchwork of local club policies.

No other states with legal recreational pot have licensed clubs statewide. Alaska is working on regulations to allow consumption where the drug is sold, but the regulations aren't up and running yet.
