TRENTON — The co-founder of the medical marijuana dispensary in Egg Harbor Township will appear in court Wednesday to dispute claims he blocked his employees' attempts to join a union in a case that is being watched across the nation.

And this isn't even David Knowlton's biggest problem.

Medical marijuana law modified

Gov. Doug Ducey signed legislation Friday that could make it a bit more difficult for some patients to get a recommendation for medical marijuana.

The law requires doctors who write most of the recommendations to document how they know the patient and their medical needs.

A 2010 voter-approved Arizona law allows anyone with certain medical conditions to get a doctor’s certification to obtain up to 2 1/2 ounces of marijuana every two weeks.

At last count nearly 66,000 Arizonans had state-issued cards allowing them to make purchases from state-licensed marijuana dispensaries.

Sen. Floyd Prozanski (D-Eugene) & Sen. Ginny Burdick (D-Portland) are pushing a bill that will close a loophole for Oregon marijuana users looking to buy firearms.

The bill, SB 941, will expand background checks required for most personal sales of firearms. The bill requires people selling a gun to go to a gun dealer and request a background check on the person they want to sell the gun to. As part of that background check, the person wanting to buy the gun will fill out ATF Form 4473.

The UpTake: Legalizing marijuana could result in a $4.1 billion Ohio industry by 2020. Those are serious numbers for those advocating for the state to join the ranks of those that already permit pot.

I an James, architect of a proposal to legalize pot in Ohio, said it stemmed from a simple notion: "Let's take this from the tie-dye to the suit-and-tie approach to marijuana."

James, CEO of the Strategy Network, a Columbus political consulting firm, turned to Cincinnati lawyer Chris Stock for help. Would Stock draft a proposed amendment to the Ohio Constitution that would outline how pot would be regulated for personal and medical use? "I've never used marijuana in my life," Stock told James. "I'm not sure I want to be involved." But he relented.

The CEO of a medical marijuana company fighting the state in court has died unexpectedly.

Andrew James, 51, was found unresponsive on Thursday at home in Kenilworth, according to the Cook County medical examiner’s office, which said Friday an autopsy was inconclusive. Authorities are awaiting the results of more tests.

James headed PMRx, a company that had applied for a medical marijuana-farming permit in the Kankakee area. When the company lost out on its bid, it sued, accusing the state of failing to follow its own licensing guidelines when scoring applications for the coveted and potentially lucrative permits.

Health care leaders and entrepreneurs are competing for five licenses to grow and sell medical marijuana in New York as patients seek improved access to the drug

A $10 million construction project tied to selling medical marijuana to Lower Hudson Valley patients is unfolding about 60 miles northwest of White Plains.

Valley Agriceuticals, a company started by a team of health care and cannabis industry leaders, wants to build a marijuana grow facility in Wallkill, a farming community of about 29,000 people in Orange County.

A recent report by The Arcview Group showed that legalized marijuana is now the fastest growing industry in the U.S., posting a whopping 74% growth rate in 2014. Despite a widespread movement to legalize marijuana for both medicinal and recreational purposes across the country, though, the industry still faces some serious challenges on the legal front that investors need to understand. 

So, to give investors a deeper look at some of the more pressing legal issues, I spoke with a leading expert on medical marijuana, Aaron Lachant -- an attorney with the healthcare specialist law firm Nelson Hardiman LLP.

As legalization spreads, in a variety of forms, managers and workers are facing some tough questions about how the new laws impact policies and practices. Let's take a look at how marijuana legalization is being handled in the workplace. First, here are a couple of things you should know.

Be sure you know your state's laws.

Regardless of your own personal feelings about marijuana, It's important to stay current on the state of the drug laws in your area, as well as your company's individual policies on drug use — especially if you're a manager. Keeping up to date with policies, whether you agree with them or not, is a crucial first step to understanding the way the changes impact your company and your team.

DENVER — While federal law makes their entire industry illegal, many marijuana store owners, growers and retailers fear something completely different: Big Tobacco.

Today, most legal recreational marijuana operations are small, limited to a single state and barred from ever getting large by regulators who want to keep a close eye on the fast-growing industry. But those small operators struggle to get bank loans for expansion, often produce an inconsistent product and sometimes have no idea how to balance supply and demand for their crops.

FAYETTEVILLE -- A panel discussion on medical marijuana offered Fayetteville City Attorney Kit Williams a chance to describe his wife's personal story of how the drug helped her while she underwent chemotherapy treatments for cancer.

But the panel at the Arkansas Health Disparities Conference at the University of Arkansas at Fayetteville also gave a Little Rock doctor, David Smith, a chance to express his concerns about the chemicals in marijuana.

Williams said his wife, Emily, suffered greatly from nausea while being treated for lymphoma, a type of cancer.

But once she began using marijuana, "the pain that she had been feeling, the nausea that had been wrecking her system, started going away almost immediately," Williams said.
