Marijuana has always been a shared experience. As a prohibited substance, users gathered together, sometimes in the shadows. Because it was once relatively scarce and expensive, it was passed around in private. And, because use enhanced experience, the smokers needed someone to listen.

That’s the story of how the Marijuana Business Conference and Expobegan as well. From about 400 people in Denver four years ago, to more than 10,000 last week. Cannapreneurs are feeling good about the prospects of legalized cannabis, despite the ambiguity on what will happen with the next presidential administration.
