AUGUSTA, Maine (AP) — Maine’s medical marijuana caregivers have held their first trade show and festival in the state.

Medicinal users with the proper legal documentation were allowed to use marijuana in a tent outside the city-owned Augusta Civic Center on Saturday thanks to an agreement by police, the District Attorney’s Office and organizers of Home Grown Maine. The Kennebec Journal in Augusta ( ) says it was the first time medical marijuana users were able to legally medicate in public.

Chris Kenoyer of Portland, a patients’ advocate and activist who uses marijuana for severe, chronic back pain caused by a degenerative spinal injury, used a vaporizer to inhale marijuana during the Home Grown Maine trade show. Kenoyer calls medical marijuana a step forward for all Maine patients.
