Two states in the western U.S. are seeing the newest gold rush, except this time its green.

Since the legalization of recreational marijuana, the states of Colorado and Washington are attracting entrepreneurs and investors to the area, and the business industry is coming together in Colorado to discuss the future of the industry, according to The New York Times.

The National Cannabis Industry Association, founded in 2010 in Colorado, held its first annual Cannabis Business Summit in the state last month.

The motto on the Web page of the event said, "Where commerce meets a revolution."

The changes in the industry are creating a change in the faces of drug users as well.

As the Wall Street Journal said, "The pot industry puts on a tie."

Weed is no longer cool, according to The Wire. It is no longer a rebel drug or one that is only used by the young and the wealthy.

It is a legitimately viable industry and business minds are taking note.

And with that comes problems like pot dealers not being able to find business insurance, according to Businessweek. Even some with ties to the industry like lawyers and doctors are being threatened with revocation.

But that isn't stopping the projected industry boom.

"It's the wild, wild West," said Tom Bollich, CEO of Surna, in Boulder, Colorado, which builds climate systems for marijuana growers.

Currently 23 states and Washington, D.C., have legalized the drug and the industry has already seen the financial impact.

The noncriminal marijuana industry has grown from $1.5 billion in 2013 to $2.6 billion this year, according to The New York Times, which cited San Francisco firm ArcView Group.
