The 2015 Cannabis Cup is happening now and enthusiasts from all across the country have flocked to Colorado for the big day. And this year’s Cup should be one of the biggest, wildest and most talked-about cannabis celebrations of all time. 303 caught up with Dan Skye, Editor-In-Chief of High Times magazine and the man behind the Cannabis Cup, to talk about all things Colorado, weed, and 4/20. Here are ten pieces of knowledge you should definitely have before heading out to party this year.

Despite the city's ban on sales, you really can get recreational marijuana in Colorado Springs. You just need to join the right club.

Private cannabis clubs got their start in Colorado Springs, which banned recreational marijuana sales after Amendment 64 legalized them in 2012.

Denver doesn't have such clubs; it has recreational pot stores galore.

And Colorado Springs residents can drive a few miles to Manitou Springs and choose their favorite flavors at Emerald Fields or Maggie's Farm retail outlets.

But public consumption of marijuana isn't allowed anywhere in Colorado.

For the second year in a row, the U.S. Cannabis Cup — the largest event in High Times magazine’s portfolio — kicked off Saturday at the Denver Mart with speakers and vendors from throughout the country, and plenty of free marijuana.

DENVER (AP) — Breaking from decades of "Just Say No"-type messaging about marijuana use, Colorado law enforcement officials are starting a new campaign designed to promote safe marijuana use.

The revised campaign starts this weekend, when tens of thousands are expected at public rallies and concerts in observation of the 4/20 marijuana holiday. A few things to know about the new effort, along with some backstory:

GOING TO THE SOURCE

The Colorado Department of Transportation is taking its campaign to the demographic most likely to use pot and then drive, according to surveys. That's men aged 21 to 34.

BASALT, Colorado — One cannabis grow in Colorado is setting the bar very high.

Puns aside, marijuana may be legal in the state of Colorado, but that doesn't mean that all plants are grown with equal care.

While visiting the state, we saw cannabis being grown inside dirt-caked retail stores, in warehouse districts tucked into industrial spaces and behind the glass of a medicinal dispensary in downtown Denver. But 30 minutes outside of Aspen, a pristine 25,000 square-foot facility set against a backdrop of blue skies and mountains is leading a push for a classier cannabis cultivation. It's pot gone posh.

DENVER - Cannabis consumers from across the country are gathering at the Denver Mart this weekend for the fifth Cannabis Cup. 

At event, which runs Saturday through the Monday, festival-goers can attend lectures on cultivation and the future of legalization.  

There's also a trade show and expo featuring the latest products and inventions. Shoppers can purchase everything from growing supplies to pot-plant shaped muffin tins.

A Saturday concert at Red Rocks will feature SOJA, Nas and JBoog.

Snoop Dogg, 2 Chainz and A$AP Rocky will be the artists at Monday show at Fiddler's Green.

"This is an economic miracle as far as I'm concerned," said Dan Skye, editor of High Times, the publication sponsoring the event. 

If the 2014 High Times Cannabis Cup felt a little too good to be true, Colorado’s Marijuana Enforcement Division (a.k.a. the MED) confirmed that with an early-April memo that warned licensed Colorado businesses exhibiting at the Cup about what exactly is and is not allowed this year.

Giving out samples? Banned. Being in an area designated for consumption? Think twice about that. Buying marijuana and personally giving it away? Absolutely prohibited.

As legalization churns along, numerous issues are slowly but surely being addressed.

With 420 approaching, it's time for our annual reminder: Don't do anything that might bring shame to Denver, Colorado, or marijuana legalization in general.

This weekend's Cannabis Cup, a trade show for those in, or interested in, the bud industry, is doing its part to keep the jackassery to a minimum by disallowing and sales or giveaways of weed-related intoxicants. This should put it in stark contrast to the Great American Beer Festival, which every October floods our downtown streets with loopy, pretzel-necklaced nimrods.

Cannabist pot critic Jake Browne and marijuana editor Ricardo Baca discuss Colorado’s Cannabis Cup, and how it might just be edging out Amsterdam’s annual event.

Listeners of KREL in Colorado Springs might have wondered if someone had spread cannabutter on their morning toast Monday when they tuned in and got marijuana programming instead of the radio station's usual sports news and talk shows.

If they turn their AM dial to 1580 again, they'll find out it wasn't a fluke.

Southern Colorado Radio - SoCo Radio for short - has launched the nation's first radio station dedicated to talk and news coverage of the legal marijuana industry, and it's attracted dispensaries as advertisers and hundreds of followers on social media.

SoCo Radio leased the former KREL-AM 1580 from Vero Beach, Fla.-based Pilgrim Communications on April 1 and began broadcasting Monday under the call letters KHIG.
