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.

Amarillo, TX - A new pro-cannabis organization in Amarillo is looking to grow its campaign by educating and registering more voters who are in favor of their message.

Amarillo Cannabis Culture knows its got an uphill battle with lots of opposition. We decided to find out for ourselves how hard that battle would be by asking area residents how they feel about the legalization of marijuana, and the responses weren't what we expected.

Growing up on New York’s Long Island, Jim Hagedorn would watch TV and see reports of marijuana busts. In the background, he’d sometimes spot bags of Miracle-Gro, the garden fertilizer invented by his father, Horace.

That recollection is particularly apt as the younger Hagedorn, now 59, considers plans for the company his father helped found, Scotts Miracle-Gro Co., the world’s largest maker of lawn-care products. This month, Scotts bought a leading supplier of hydroponics, a technology that allows indoor cultivation of everything from tomatoes to pot without soil.

Last November, voters decided it was time for Alaska to take a more sensible, reality-based approach to marijuana. They replaced the failed policy of prohibition with a mandate that the state regulate and tax marijuana similarly to how we treat alcohol. Yet, with only days left in the legislative session, the Legislature has yet to provide the resources needed to establish a regulatory framework.

For all those that celebrate 4/20, read these quotes from more supporters.

A Hayward man was arrested after 4,859 marijuana plants and three pounds of processed marijuana was found at a warehouse on Stone Road in Benicia Thursday morning.

Thuy Dinh, 34, was taken into custody and arrested by Solano County Detectives after he tried to flee the warehouse through the back door. He was booked into the Solano County Jail for cultivation of marijuana, possession of marijuana for sale, conspiracy to cultivate, distribution of marijuana and resisting arrest.

The Solano County Sheriff's Office said the warehouse was divided into 10 rooms, calling it "a very large and sophisticated marijuana growing and processing operation."

Hopes were raised and dashed for supporters of marijuana legalization this Wednesday as U.S. District Judge Kimberly J. Mueller upheld marijuana’s status as a Schedule 1 drug fully constitutional. Being the first judge in decades to reexamine marijuana’s classification under the Controlled Substances Act, Mueller offered a potential step forward in examining marijuana from the federal standpoint, but she did not feel it was in her power to make that change.

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.

Spare a thought for Bert Trautmann, a goalkeeper who suffered two cracked vertebrae in his neck while playing for Manchester City in the 1956 FA Cup final. “He played on for the last 15 minutes and made saves that won them the game,” says Prof David Finn. No subs were allowed back then.
