The nation may not know who is president on election day, but the people have spoken when it comes to cannabis legislation. Arizona, Montana, New Jersey, and South Dakota have all legalized marijuana for adults 21 and older, as voters in each state approved their respective ballot initiatives at the ballot box. The Garden State has gone green as the closely watched state of New Jersey approved adult-use cannabis.

Now that Las Vegas has officially started selling recreational marijuana as of Saturday, pot tourists should learn the rules before they get high, legal experts say.

In Nevada, gambling, drinking, and even some prostitution is allowed. Marijuana may fit right in.

"It's always crazy, so it's going to be fine, I guess," said Ilze Mondragon who was flying to Las Vegas for her birthday.

It's estimated two thirds of recreational marijuana users in Las Vegas will be tourists, so what do locals think?

"There are still a lot of legal ramifications," Las Vegas resident Spencer Cranney said.

You can't use marijuana in hotels, on the Strip, in public, or in restaurants.

The number of women using medical marijuana to treat their pain is up drastically over the past five years, according to the Arizona Department of Health Services.

The report says 25 percent of women in 2012 used medical marijuana compared to more than 37 percent as of May of this year.

Wendy Cardona, a stay at home mom of two is looking to treat her chronic pain.

"With the pain that I have, it's hard for me to play with them. I have to pause on them which they don't understand," Cardona said.

She's tried other medications, both over the counter and prescription, but so far nothing has helped. That's why she decided to try medical marijuana.

Two major research universities have cut ties with a Valley doctor’s efforts to answer this question: Does smoking marijuana help veterans struggling with post-traumatic stress disorder?

Dr. Sue Sisley, who was fired by the University of Arizona in 2013 after her study was underway, learned in March that Baltimore-based Johns Hopkins University has dropped plans to partner on the first-ever study of cannabis for veterans.

Beyond Sisley losing a prestigious research partner, the Johns Hopkins departure means study backers won't have access to Baltimore-area veterans and must recruit study participants from Arizona.

The treatment center Blue Door Therapeutics is combating the opioid epidemic with cannabis pills and patches in response to painkillers' often agonizing withdrawal symptoms. According to doctors at the Scottsdale, Arizona facility, a chemical in marijuana with "anti-inflammatory and anti-anxiety properties" can "help stabilize the patient's underlying condition," reported ABC15.

Cannabis oil as a sunscreen additive?

'I've been preaching about [how] cannabis cures cancer since 2008," Laurie Gaddis says. And she's been preaching it because it works.

Gaddis moved to Colorado from Arizona after she was diagnosed with a rare form of skin cancer she says comes from her father's exposure to Agent Orange in the Vietnam War. She says she's been a medical marijuana refugee for nearly a decade.

The patchwork of state laws under a federal ambiguity that has gotten worse with Attorney General Jeff Sessions' anti-pot statements has created hundreds of medical marijuana refugees who have to move to a state where they can get the kind of medicine either they or their doctor feel is necessary.

It’s hard to imagine an analytical test without lab work, but that’s just what dry labbing means. In some cases—increasingly few—samples of cannabis get certified, as if they were tested, when nothing was really done, no wet-lab science was performed. Instead, these samples get labeled with characteristics that no one really measured. Put very bluntly, dry labbing is lying—making up data about what’s in a product rather than testing it. For medical use, dry labbing is dangerous, because someone could get a higher dose than expected or not enough of the medicine they rely on. On top of that, it’s fraud for both medical and recreational cannabis products.

A judge has rebuffed efforts by medical marijuana users to force the state to reduce the fees it charges patients.

Maricopa County Superior Court Judge Jo Lynn Gentry said she does not dispute that the Department of Health Services is collecting more from medical marijuana users than it needs to administer the program.

In fact, documents obtained by Capitol Media Services show that this fiscal year, which began in June, the agency has taken in more than $19.9 million in fees. By contrast, expenses in the same period total less than $7.8 million.

And the balance in the fund, which rolls over from year to year, now exceeds $31 million.
