Nevada takes lessons from Rocky Mountain State.

One billion dollars in marijuana was legally sold in Colorado in 2015. Colorado has become a case-study for states, including Nevada, facing ballot initiatives this November to legalize recreational marijuana. A contingent of industry representatives and lawmakers recently traveled to Denver on a fact-finding trip. 8 News NOW also made the trek.

Nevada, California, Maine and Florida have recreational marijuana on the ballot in November. Other states like Arizona are waiting on signatures to be verified to qualify for the ballot.

These states are all watching Colorado. Medical marijuana has been legal there since 2000, and voters approved recreational use in 2012.

With around four months to go ahead of the November elections, observers of America’s marijuana legalization movement are closely watching the legal and political maneuvering underway on both the state and national level.

Voters in about a half-dozen states are expected to decide on cannabis legalization measures this election; and several of those states might join Alaska, Oregon, Washington State and Colorado in allowing the legalization of recreational marijuana use for adults.

But despite the apparent momentum for marijuana legalization the regulatory landscape still remains quite unsettled, notes Sam Kamin, the Vicente Sederberg Professor of Marijuana Law and Policy at the University of Denver.

If recreational marijuana becomes legal in Massachusetts, it won’t be just for smoking.

Edible marijuana products – a broad category that could include such treats as cookies and candy – would also be permitted under the ballot question nearly certain to go before voters in November. As the legalization debate heats up, the smoke-free forms of the drug are quickly emerging as a central focus of discussion.

Edibles caught the attention of the state Supreme Judicial Court, which this past week pointedly ordered revisions to a summary designed to explain the question to voters. The justices said it was misleading not to specify that legal marijuana could include food products.

Ohio could be the first medical marijuana state to fix the industry's cash-only situation.

Half the states and the District of Columbia have legalized medical marijuana but the federal government still considers it among the most dangerous drugs. Banks, credit unions and credit card companies are reluctant to provide services to legal marijuana businesses because of uncertainty from federal regulators, leaving most businesses to operate as cash-only.

Ohio's new medical marijuana law proposes a new way around the bank problem. The law allows state officials to set up a "closed loop" payment processing system, similar to prepaid debit and gift cards.

Hawaii patients have more options to gain access to medical marijuana now that nurses can certify people for use of the drug, a change advocates say was needed because there's a shortage of doctors willing to do the certifications.

Gov. David Ige signed a bill Monday updating the state's medical marijuana dispensary law.

"It's high time that this bill came into effect," said Wailua Brandman, a psychiatric nurse practitioner. "I have patients that have been using marijuana, not legally, because they don't have the diagnosis yet ... but the medication is working for them, and they keep asking me, can they get a card?"

He’s actually 6 years old. It makes so much sense now.

You may have been following this year’s tumultuous election a bit on autopilot. And one could hardly blame you. But it’s hard to ignore Donald Trump, even though you/I/we desperately want to.

He reminds you of someone. You can’t quite put your finger on it. The loud, cocky attitude delivered with all the subtlety of a 6-year-old. Oh wow, Donald Trump is Calvin from “Calvin and Hobbes.”

And to answer the question you never asked, YES, there is a subreddit dedicated to injecting Trump into “Calvin and Hobbes” comic strips.

A former pro football player and a Novato advocate for athlete marijuana use have teamed up to open a gym in San Francisco that they say will be one of the first in the world to allow members to smoke pot while working out.

Former running back Ricky Williams, who played for the Saints, Dolphins and Ravens, and Jim McAlpine, a snowboard company executive, said Power Plant Fitness also will offer edibles and topical gels for those who don't like smoking the plant. They say using pot while exercising can help them focus or relax.

Members of the gym, which plans to open this year, will need a medical marijuana prescription to join, but that could change if California voters legalize recreational pot in November.

New Ohio laws hit the books in September, legalizing medical marijuana - a drug Northside’s Nicole Scholten believes will help her daughter Lucy and thousands of sick and suffering patients across the state.

But just how soon patients like Lucy might be able to get the drug in Ohio is still a big unknown.

“Thank goodness the law has been passed, but good luck finding a doctor who will recommend it,” said Scholten, whose daughter Lucy has cerebral palsy and more than 150 epileptic seizures a day. “If you can’t find a doctor, it may as well be illegal.”

While Ohio's medical marijuana law goes into effect Sept. 8, it doesn't require the system to be fully operational until September 2018.

After a five-year struggle in the General Assembly, Pennsylvania became the 25th state to legalize medical marijuana on Apr. 17. But it will take at least six months for the Dept. of Health to craft regulations that permit this new industry to begin, with a couple of years of road-testing after that.

This process began with a bang at St. Joseph’s University on Jul. 8, where State Sen. Daylin Leach (D-Montgomery), the prime sponsor of Act 16, convened a “Medical Marijuana Regulatory Palooza” that drew 300 experts from across the nation – physicians, lawyers, businesses, producers, patients and public officials – to share their experiences in the industry, in hopes that the Keystone State can learn from others’ successes and snafus.

There are many myths about use and possession of marijuana and medical marijuana in Arizona, especially since the Arizona Medical Marijuana Act passed in 2010. Here's what you need to know about what is and isn't allowed, and the legal consequences.

Can I be fired for using or possessing medical marijuana legally?

A patient can be fired if he or she is in possession or under the influence of marijuana at the workplace.

It is illegal for an employer to take adverse action against an employee because of cardholder status or a positive test for the presence of marijuana, unless the employer would lose federal funding or licensing for not taking action. It does happen but often never makes it to court, according to marijuana lawyer Thomas Dean.
