As more states contemplate legalizing recreational marijuana, the businesses that pop up are going to need banking solutions. Fortunately for them, more US banks are becoming willing to dabble in the cannabis trade.

Over the last two years, the number of banks and credit unions open to dealing with marijuana businesses has increased by almost six times, the Associated Press reported, citing federal data. Back in March of 2014, only 51 banks and credit unions in the country were willing to deal with cash from pot businesses, but the number now stands at 301.

Fortune takes a look at the influencers on 4/20. 

America’s marijuana industry has bloomed in recent years with voters in more and more states voting to legalize pot in some form as public opinion on the drug seems to evolve with each generation.

Heavy snow in Colorado this past weekend put a damper on the celebrations leading up to 4/20, the annual April 20 celebration of all things marijuana-related that occurs on Wednesday this year. On Saturday, organizers scrapped a major cannabis rally in downtown Denver at the last minute, and hundreds of flight cancellations at Denver International Airport frustrated the plans of travelers aiming to spend the week sampling the state’s legal cannabis market in honor of the cannabis high holiday. But that didn’t mean folks weren’t still ready to pre-party.

This year alone there have already been more than 50 legislative initiatives around the country aimed at legalizing or decriminalizing medical or recreational marijuana. 

Will marijuana legalization in Colorado cause pot use and abuse to skyrocket, along with other problems associated with cannabis? Or will it be a net gain, creating new jobs in a burgeoning industry while cutting arrests for a relatively mild drug?

A new report from Colorado finds a little bit of the first and a little bit of the second.

The report, filed by the Colorado Department of Public Safety for the state legislature, had several big findings:

The state released a report Monday detailing changes in everything from pot arrests to tax collections to calls to Poison Control.

Colorado kids are not smoking more pot since the drug became legal — but their older siblings and parents certainly are, according to a long-awaited report giving the most comprehensive data yet on the effects of the state's 2012 recreational marijuana law.

The state released a report Monday detailing changes in everything from pot arrests to tax collections to calls to Poison Control. Surveys given to middle-schoolers and high-schoolers indicate that youth marijuana use didn't rise significantly in the years after the 2012 vote.

Hospitals and treatment centers in Colorado have seen an increase in marijuana use among patients since recreational pot became legal in January 2014, while weed-related arrests have predictably plummeted significantly, a new report reveals.

While the author of an 147-page study released by the Colorado Department of Public Safety on Monday cautions that it’s too soon to truly measure the impact of the state’s first-in-the-nation recreational marijuana laws, statistics so far suggest that facilities have seen an explosion with respect to patients who have either been hospitalized as a result of weed.

“Whether novice or aficionado, knowing how to assess cannabis flower quality is key to having the best possible experience.”

All Cannabis is not created equal, and just as wine enthusiasts enjoy a user friendly tasting system and diamond buyers employ the “Four C’s,” Good Chemistry Nurseries, one of the industry’s most experienced Cannabis producers has now created a stylish, easy-to-use free consumer cannabis evaluation guide for assessing quality cannabis flower.

With medical marijuana now legal in 23 states — and recreational weed legal in four — the conversation about pot will only continue to buzz. Soon, weed as research, as medicine, and as business may no longer be a taboo topic.

But what parts of the country talk the most about marijuana? Denver may be the first to come to mind, since it was the first to legalize recreational use, but a new report from Aizman Law Firm finds this isn’t always the case. The law firm decided to see what U.S. cities mentioned weed on social media the most, so it analyzed geotagged Instagram posts hashtagged with the phrases #weed, #maryjane, #marijuana, or #420.
