What is believed to be the largest medical marijuana trade show in New England is coming to Bangor on Saturday.

Homegrown Maine 2014, which is organized by the Medical Marijuana Caregivers of Maine, will take place at the Spectacular Events Center. A spokeswoman for the organization said the event is geared for caregivers, patients and growers. The organization estimates that thousands of people will attend the event.

The event will include a talk from Dustin Sulak, a Falmouth-based osteopathic physician, about recent scientific research about medical marijuana. State Sen. Geoff Gratwick, a Democrat and Bangor-based physician, will talk about hospice and medical marijuana. There will also be arts, crafts, music, legal services and smoking supply vendors, organizers said.

The trade show also includes a smoking tent outside the facility for qualified users. Organizers said the event will also include workshops, classes, vendors and performances.

There will be no marijuana for sale at the event.
