We asked three who’ve gone from Wall Street to the C-suites of the cannabis industry to tell us what they found. Derek Peterson, CEO/Founder of Terra Tech, the first publicly traded cannabis company in the U.S. worked as a Vice President with Morgan Stanley.

A few months ago Cathy Ritter was settling into Denver's Congress Park neighborhood with her husband, walking to Rockies games and relishing being close to her daughter's family.

Then the former director of the Illinois Bureau of Tourism saw a job posting that could work for her.

On Thursday, Gov. John Hickenlooper named her as the new director of the Colorado Tourism Office, replacing Al White.

Ritter — no relation to former Gov. Bill Ritter — plans a 90-day listening tour of Colorado.

"I want to get familiar with the faces and places of Colorado so I can be as informed as possible," said the 13-year employee of the Illinois government and former newspaper reporter.

Last week, as the glorious autumn foliage blazed out across America’s Midwest, I travelled to Kansas City for an economics seminar. I found a place throbbing with joy: the Kansas City Royals, the local baseball team, had just won the World Series, against steep odds. It was also a city full of political debate, largely about Donald Trump and the other Republican candidates.

CHICAGO (AP) - Illinois' new medical marijuana shops sold nearly $211,000 worth of cannabis in the first week, with less than a quarter of eligible patients buying so far.

The state's first regulated marijuana dispensaries opened Monday.

Program director Joseph Wright said Friday the dispensaries served 806 customers. They purchased about 460 ounces of marijuana, or about a half an ounce per person, on average.

Green Thumb Industries CEO Ben Kovler says the numbers are "a very strong start."

What a thriving business it is for Marijuana shop owners in Oregon as news reveals more places to get pot in the state.

Latest news has revealed that the number of Marijuana shops have increased in the state of Oregon, and it's mostly because of medical requirements although recreational use has already been legalized.

Is the idea of medical marijuana providing benefits to patients a "joke"? According to DEA chief Chuck Rosenberg it is.

Marijuana legalization has witnessed explosive expansion over the past decade, but November has been a pretty tumultuous month for the illicit drug thus far.

The explosion of coverage on opioid abuse has been chilling for many chronic pain patients who use opioids responsibly to manage their pain. In many cases, with heightened scrutiny over its merits of use, reduced access becomes an issue.

Many chronic pain sufferers have turned to medical marijuana, which has far fewer side effects than opioids. The problem there is also access. Medical marijuana is only available in 23 states and the District of Columbia and, of course, there are complications because the federal government still deems marijuana illegal so people in the federal health care system (like the VA and Medicare for instance) often can’t get medical marijuana prescribed.

THE MICHIGAN STATE POLICE Forensic Science Division finds itself embroiled in scandal as newly released emails paint a picture of a crime lab in turmoil over how to classify marijuana. Attorneys and medical marijuana advocates accuse Michigan prosecutors of pressuring the state’s crime lab to falsely classify the origins of THC found in hash oils and marijuana edibles as “origin unknown.”

The Florida Supreme Court is canceling a Dec. 8 hearing scheduled to consider a measure to legalize medical marijuana.

The court announced the decision Friday. The move comes a few days after Attorney General Pam Bondi said she will not ask the court to block the latest medical marijuana amendment.

The Supreme Court is reviewing the ballot initiative. Justices must decide whether or not the amendment is misleading and whether it complies with single-subject requirements.

Supporters tried to pass a similar amendment during the 2014 election. That ballot measure failed because it did not meet the 60-percent threshold needed to pass.

Joe Brennan faces a lot of the same worries as all businesspeople — sourcing inventory, regulatory headaches, competitors popping up like weeds.

But those weeds give Brennan a whole new set of worries. His business? Mindright, a medical marijuana dispensary in Detroit.

Brennan said he has tried to do everything legitimately. But he is in an industry that is known for angering neighbors, accused of promoting drug abuse and inviting heavy scrutiny as dispensaries proliferate in the city.

Before opening earlier this year, he obtained a city license for a retail-medical sales business, bought insurance, hired a security guard and made sure his marijuana products were tested for purity. "We want to be completely professional," he said.
