Hundreds of so-called “ganjapreneurs” swarmed New York this past weekend to learn about the business side of the cannabis industry, while also checking out products displayed by a few of the many companies with designs on hawking the next big marijuana-related item.

The International Cannabis Association (ICA) hosted its first East Coast Cannabis Business Expo from Saturday through Monday evening in New York City at the Times Square Marriott Marquis. The “educational conference and regulatory summit” was billed as an event for people with designs on staking out their own corner of the cannabis industry when the medical marijuana market hits New York sometime in the next couple of years, after a new law was signed earlier this year.

A spokeswoman for ICA says roughly 900 people attended this week’s conference, where they heard from some of those state regulators, including State Senator Diane Savino, who sponsored the medical marijuana bill in New York and who spoke at the conference and also hosted a campaign fundraiser. There was also a full slate of instructional seminars with topics ranging from “Seed to Sale Tracking” to “Employment Law Issues Arising out of Medical Marijuana Use.”

Those in attendance also mingled with dozens of vendors who have already established marijuana and hemp-related businesses in states where their products are already legal. Here’s a look at some of the most interesting products and businesses featured at the conference.
