Handblown glass pipes and bongs are displayed in antique cabinets at the Farm, a marijuana dispensary in one of two states that have legalized the drug.

The walls feature paintings by local artists. There are vaporizers, electronic cigarettes, rolling papers and more. That’s just in the front of the store.

In the back room, “budtenders” are selling gluten-free edibles, lollipops, salves and, of course, marijuana.

Jan Cole’s company grows and harvests its own marijuana strains, but the Farm depends on vendors to provide many of the products sold at the store. The business employs 103 people.

Behind the scenes, there are accountants, lawyers, janitors, Internet providers, soil companies, testing laboratories and more.

The cannabis industry isn’t just pot shops and warehouse grows. It’s an industry that could reach $2.57 billion in value this year, according to the Arcview Group, a San Francisco investment and research firm that focuses on the cannabis business.

The National Cannabis Industry Association has more than 500 members and will hold the first National Cannabis Business Summit in Denver for more than 800 people in late June.
