Organizers, who touted the event as the "largest cannabis convention in the United States", said the convention was put on to showcase the "level of professionalism" in the medical scene here in Colorado.
Inside the hall, "professionalism" took on quite on a few forms, as you'll see from our photo gallery below.
While some dispensaries opted for simple setups showcasing pictures of their medicine and maybe a massage chair, others hired scantily clad women to hand out fliers promising discounts and freebies.
The convention was open to anyone, medical card or not. A wide range of people, from teenagers to retired couples, walked the hall. Some families even toted along young children.
Jason, a nineteen -year-old Metro student, and his friends walked around the hall for about 45 minutes collecting as many coupons as they could.
"This is exactly what I was hoping this would be like," he said. "Now I just got to go to all these dispensaries for the free weed."
Aside from the dispensaries there were plenty of vendors on site selling just about anything related to the medical marijuana industry -- from trimming machines to security systems. Some people were even cashing in on several businesses.
Behind the table at the DoobTube booth, owner Ray C. handed out his invention to passers by. Ray said he was hoping to score deals with dispensaries over the weekend to start carrying his index-finger sized clear plastic joint tubes embossed with Amendment 20 of the Colorado Constitution on them.
"This is the best time to get to see all these dispensaries," he said.
On the opposite end of the hall, Trent Sybert was demonstrating a Dutch joint rolling machine that pops out sixty perfect cones in fifteen minutes. The company also makes individual cone-rolling-kits that were a hit with visitors in the convention hall, but like Ray at DoobTube, Sybert said he hoped to be making bulk deals on his product.
On the stage in the back of the hall, a revolving door of performers, lecturers and panels -- including a town hall with Representative Jared Polis -- went from opening until close, often to a near-empty audience. Cypress Hill was on hand signing autographs on Saturday, though the rap trio didn't perform.
The convention nearly didn't go on after the original promoters allegedly disappeared after taking money from vendors. Sponsors dailybuds.com and Kush Colorado Magazine - both owned by ganjapreneur and advocate Michael Lerner - took over handling the event.
