A Colorado proposal to certify organic marijuana has been rejected amid concerns the labels would imply pot is healthy.

The bill rejected in a legislative committee Tuesday would have created a first-of-its-kind label for marijuana that had been produced without pesticides.

The proposal failed 4-3 in a Senate committee. Some lawmakers said the labels could wrongly imply that marijuana is harmless.

Big changes are coming for Denver businesses that cause odors, specifically marijuana grow operations. The Denver City Council has passed new rules regulating the smell.

One area the Department of Environmental Health said generates the most complaints is North Denver. The organization in Denver receives about 100 formal complaints a year.

“A lot of it is marijuana,” said Department of Environmental Health spokesman Gregg Thomas.

Thomas said since the legalization of marijuana, the department has been looking at new ways to regulate air pollution. Now that the city council has made its decision, Thomas said they finally have the ground work.

“It’s partly a brave new world we are entering into,” said Thomas.

1-800-Flowers CEO Jim McCann says that despite the company’s efforts to utilize domestic flower growers, the growers in certain states are considering growing marijuana as a potentially more profitable option.

“We have been pushing for domestic production of flowers hard for the last 10 years and having real good success,” McCann told the FOX Business Network’s Maria Bartiromo.

But McCann noted that many flower growers are now tempted by the huge potential revenue boost from growing cannabis instead.

A few months ago, we wrote about why cannabis legalization doesn’t lead to higher teen use rates. A recent Washington study from the American Academy of Pediatrics bolsters that claim with new evidence showing that minors do not feel cannabis has been any easier to obtain since the state legalized recreational use in 2012. This data comes from the Washington State Healthy Youth Survey which polls tens of thousands of students each year across hundreds of schools.

The forecasts for legal U.S. cannabis sales are in the billions.

But entrepreneurs in the weed trade, despite landing in hot markets like Colorado, face a bit of a reality check. That's due, in part, to a lack of traditional financing tools like banking, and still growing stream of venture capital into the industry.

"There's this misconception that everyone is rolling in the money here," said Jill Lamoureux, a Colorado-based cannabis business expert.

Colorado’s tourists would be able to buy as much marijuana as residents, if a bill moving through the state Legislature passes.

The measure repeals Colorado’s unique-in-the-nation tiered purchasing system for marijuana. All adults over 21 here are allowed to possess an ounce of marijuana — but retail pot shops can’t sell more than a quarter ounce in one day to people without Colorado IDs.

The purchasing limits were established in 2013 to prevent marijuana diversion out of state. Lawmakers figured that visiting tourists wouldn’t blaze through a full ounce before heading home. An ounce of pot is sometimes compared to a keg of beer because it’s difficult for most users to finish in a few days.

Sara Williams just isn’t that comfortable with handling $10 million in cash.

Williams is the CEO of Midnight Greenery, a retail store she and co-owner Tina Smith plan to open in Anchorage this year to sell cannabis flowers, concentrates, oils, edibles and other products.

But like most who are eager to get into Alaska’s marijuana industry, Williams is worried about what to do with all the incoming cash that she can’t keep in a bank -- especially if business goes well.

Most banks want nothing to do with marijuana businesses because cannabis is still illegal at the federal level. That means businesses like Midnight Greenery will have to deal almost entirely with cash.

Credit union chartered by state of Colorado asks appeals court to look again at case demanding access to federal banking system

The Fourth Corner Credit Union on Friday appealed a lower court's ruling that denied its bid to become the first Colorado credit union for the marijuana industry.

Colorado Department of Public Health and Environment is hiring a "marijuana health effects" manager

Colorado health officials want to hire somebody to keep an eye on marijuana legalization — at potentially one of the highest salaries in state government.

Nebraska Attorney General Doug Peterson and his counterpart in Oklahoma are joining a lawsuit aimed at halting legal marijuana in Colorado.

The two states asked to be added as plaintiffs this month in a case being considered by an appeals court in Denver, the Lincoln Journal Star reports.

The appeals court in Colorado hasn't given a timeline for addressing the request, but allowed lawyers for the states to make merit-based arguments in briefs due May 23. That means Nebraska and Oklahoma can argue the issue itself as if they were already part of the case rather than restating their reasons for wanting to join as plaintiffs.
