Massachusetts cannabis consumers will be able to participate in the Best in Grass Massachusetts 2026 competition to help select the state's top licensed cannabis products. Insa will offer its Best in Grass Judge Kits at four Insa retail locations — Avon, Easthampton, Salem, and Springfield — while supplies last. More than 3,100 judge kits have been assembled for the statewide competition, according to Insa. Judge kits will go on sale in-store starting Saturday, Aug. 1. Judge kits are available only for in-store purchase at participating Insa dispensaries.
