DENVER (AP) - The Denver County Fair is dropping marijuana exhibits from next month's event, a year after some people said they were unwittingly served pot-infused chocolate in the fair's "Pot Pavilion."

The organizer of the county fair insists that the fair is dropping marijuana not because of that incident but because marijuana-related vendor sales were slow. Dana Cain says that Denver has so many marijuana-related festivals that the drug has "become kind of old hat."

Surna, Inc. (OTCQB: SRNA), a technology company that engineers state-of-the art equipment for controlled environment agriculture ("CEA") with special expertise in cannabis cultivation, announced today the filing of two additional patent applications with the U.S. Patent and Trademark Office ("USPTO").

The two applications describe critical components of the Company's innovative hybrid growing facility, which is currently in development. These are the first patent applications Surna has submitted to the USPTO that cover its turnkey hybrid facility concept.

The cost of getting high is getting lower

After about 18 months of legal recreational marijuana sales in Colorado, the market keeps getting bigger. And now a new survey shows that pot prices in Colorado are actually declining, even as the number of customers increases.

It's been a little over a year since Colorado began allowing stores to sell marijuana for recreational use and the market continues to grow rapidly. But there are clouds (ahem) on the horizon.

Nicholas Colas and his team at Convergex, a global brokerage company based in New York, surveyed a number of marijuana stores in Colorado last week to get a better picture of the state of the nascent market.

What they found was that prices are declining faster than some had expected, while the number of people visiting the stores has increased.

Here's more from the note:

A new summer camp is set to open in Colorado where punters climb cliffs, zip line, cycle and hike – but with a newly legal twist.

CannaCamp, which opens at the start of next month, encourages users to bring their own cannabis for recreational use all over the grounds.

Getty Smoke away: Revellers are actively encouraged to smoke weed on the resort

At the camp, which comes as legalisation for the drug becomes an increasingly hot topic, revellers can enjoy lessons on cooking with marijuana and get cannabis-infused massages.

Some more artistic lovers of the drug can try their hand in an art class or relax with what organisers call "cannabis yoga".

DENVER — Some people who prosper in life choose to spend their hard-earned millions on private planes. Some buy a vineyard in Napa to indulge a love of wine. Some collect showpiece cars, or fulfill a dream of hiking Mount Everest.

Marc Paskin bought a radio station in Colorado and converted it to a marijuana-themed format.

Though cannabis in general has a learning curve, perhaps the most intimidating and mysterious aspect for new users is concentrates.

When a customer walks into a medical dispensary or recreational shop looking to try something new, a query about concentrates often results in a barrage of unfamiliar terms, and he or she has little to no frame of reference for quality, dosage, expected effects or ways to consume.

A Colorado man has been sentenced to prison in a marijuana case in Iowa.

George Podes, 44, of Denver, received a sentence of 96 months in prison on Thursday.  He pleaded guilty to conspiracy to distribute at least 100 kilograms of marijuana.

He was also ordered to serve four years of supervised release after the imprisonment.

Authorities said that between May 2011 and March 2013, Podes agreed with several individuals, including Jared Fromknecht, Morgan Hermiston, Charles Williams, Harrison Summers, Jacob Aldrich, Michael Wood and Austin Iossi to manufacture and distribute marijuana.

Authorities said Podes grew the marijuana in Colorado for distribution in Iowa.

My home state of Maine is in the middle of a battle to let voters decide whether or not to allow marijuana to be legalized for recreational use. While there are certainly passionate people on both sides of the issue, there seems to be a lack of desire for honest discussion between the groups. Either marijuana is the best thing ever--or the worst.

Take for instance this exchange printed in the Bangor Daily News yesterday, in which an anti-marijuana legalization speaker described the effects of a "marijuana overdose." According to Bruce Campbell, the clinical director at an addiction treatment agency, it is "a problem" that marijuana overdoses do not resemble overdoses of alcohol or heroin.

Our coverage of 4/20 weekend raids at two Denver marijuana clubs highlights a continuing area of concern for cannabis activists: While locals and visitors can legally consume pot recreationally in Denver, they aren't allowed to do so in social settings outside private homes.

Now, Mason Tvert and attorney Brian Vicente, the two most prominent proponents of Amendment 64, the 2012 measure that made limited legal recreational marijuana sales legal in Colorado, are prepping a new Denver ordinance expected to be called "The Limited Social Marijuana Consumption Initiative."
