With its rough-sawn cedar walls, burled maple counters and muted colors, William Simpson's upscale shop in downtown Dundee could easily be mistaken for a wine tasting room.

Thing is, Simpson's not selling Oregon pinot. He's selling pot.

The recent opening of Simpson's store in Oregon wine country signals the latest evolution in an industry going mainstream. The Portland market is saturated with marijuana dispensaries, prompting a handful of entrepreneurs to set their sights on a different crowd: tourists.

U.S. college students today smoke weed at a higher rate than at any time in the past 35 years, surpassing daily cigarette smoking for the first time in 2014.

But students are into more than pot. The study also shows ecstasy and cocaine use are rising. They’re imbibing less, though: Consumption of alcohol, the quintessential party drink, is on the decline.

Those findings were revealed Tuesday in Monitoring the Future, an ongoing study from the Univ. of Michigan.

The national survey looked at the drug use of approximately 1,500 students enrolled full time at 2- and 4-year colleges. Here, we break it down for you:

History will be created in Negril, Westmoreland, between November 12 and 15 when Rastafari In Inity (RII), in association with the internationally known High Times Magazine, Rastafari Rootzfest, the inaugural ganja festival, in the resort town of Negril

"The feedback has been great both locally and internationally," said Ras Iyah V, CEO of RII and chairman of the Westmoreland Hemp and Ganja Farmers Association. "We have gotten all the requisite permits and we are now ready to create history. This will be the first legal ganja event to take place in Jamaica."

A man sentenced to life without parole on a marijuana-related charge was freed Tuesday from a Missouri prison after being behind bars for more than two decades — a period in which the nation’s attitudes toward pot steadily softened.

Family, friends, supporters and reporters flocked to meet Jeff Mizanskey as he stepped out of the Jefferson City Correctional Center into a sunny morning, wearing a new pair of white tennis shoes and a shirt that read “I’m Jeff & I’m free.”

“I spent a third of my life in prison,” said Mizanskey, now 62, who was greeted by his infant great-granddaughter. “It’s a shame.”

Nearly six months after the city of Denver began a crackdown on unapproved pesticides in marijuana products, a spot-check by The Denver Post found that the chemicals were still being sold to consumers.

Eight lab tests commissioned by The Post on recreational marijuana extracts purchased at two shops found most contained no pesticides that are not approved by the Colorado Department of Agriculture.

But two tests on concentrated marijuana products sold at one store found levels of three pesticides the state says cannot be used to grow marijuana. Both items were manufactured by Mahatma Concentrates in Denver, which made its extracts from raw marijuana grown by Treatments Unlimited, which operates the Altitude shops in Denver.

In a little over three weeks from now, I will make my first legal purchase at a marijuana outlet in Oregon. It will not be my first time ever purchasing marijuana at a legal store, as I have already made a purchase in Washington and Colorado, but I haven’t made one in Oregon yet since it’s not legal to do so yet. But come October 1st, I will be one of the many people standing in line waiting make my first legal recreational marijuana purchase in Oregon. I personally plan to go to Panacea in Portland for my first purchase, and encourage others to do the same. To see why, check out a recent article I wrote about Panacea.

It's been 15 years since Nevada voters approved a ballot measure legalizing medical marijuana in the state, but it wasn't until August 24 that the first dispensary opened its doors in Clark County.

"We've been so busy, there are lines around the corner at some times of the day," said Euphoria Wellness Managing Director Darlene Purdy.

Located in southwest Las Vegas, the dispensary has seen more than 100 patients per day, according to Purdy, some of whom have been emotional about finally being able to purchase their medicine legally.

"Patients are so happy," Purdy said. "Some people have been waiting 15 years for this."

Most Native American tribes are opting not to legalize marijuana, though at least two are poised to try it — just six months after a Justice Department memo indicated federal authorities likely would not interfere with growing marijuana on tribal lands if other federal crimes were not committed.

Many tribes exploring their options said that as U.S. citizens and sovereign nations, they deserve the right to choose to legalize as states have done. However, tribes continue to balk at the vague language of the Justice Department's so-called "Cole Memorandum" and the fear of federal prosecution.

Alaska cannabis businesses can sell you a hoodie, so long as the transaction is being recorded in high-definition.

The Alaska Marijuana Control Board covered allowable advertising strategies or retail dispensaries, as well as security protocol last week, on the second day of an extra meeting to consider draft regulations.

Board Director Cynthia Franklin argued Montana's greatest mistake was allowing too much advertising for medical marijuana. Montana legalized medicinal marijuana in 2004 only to have a ballot initiative introduced in 2014 to recriminalize it. This followed a ballooning industry that roused the ire of the state legislators and a 36 percent minority of the population who hadn't supported legal medicinal marijuana in the first place.

Two-legged or four-legged, some guinea pigs have more fun than others.

Among the human variety, Dr. John Clendinning and Dr. David Casarett might be considered particularly fortunate. Back in 1843 Dr. Clendinning, a London physician and bad insomniac, reported on his personal experiences with various sleep-inducing substances. The clear winner was a tincture of marijuana, which brought him a good night’s sleep with none of what he termed opium’s “inconveniences.”
