In the absence of reliable federal standards and amidst growing public skepticism of industrialized medicine, Cannabis Farmers Markets offer a radically transparent, community-rooted alternative for accessing medical cannabis. These informal, decentralized gatherings empower patients to engage directly with microgrowers—producers who prioritize quality, soil health, and terpene expression over scale and profit. This paper explores how Cannabis Farmers' Markets restore trust in medicine, reframe cannabis as community care, and offer a post-industrial model for decentralized health access. In a moment when corporate science often contradicts lived experience, “know your grower” may be the most rational public health strategy available.
