From Patient to Pioneer: Lee Simpson’s Story

Before founding King Harvest, Lee Simpson was battling debilitating seizures, anxiety, depression, and PTSD. When traditional medicine failed, cannabis oil became a lifeline—halting his seizures and restoring balance. This personal transformation inspired the launch of King Harvest in 2011 with a mission to provide organic, full-spectrum cannabis that’s lab-tested and personalized for healing.

How the Seed-to-Patient Model Works

King Harvest controls every step: selecting organic Cannabis Sativa and Indica strains, performing ethanol-based extraction, and verifying results via third-party lab testing. This vertical integration ensures potency, consistency, and safety—with all products designed to optimize the Entourage Effect and backed by 1:1 consultations.

The Power of Vertical Integration in Wellness

With a projected $39B industry value in 2025 and increasing consumer demand for clean-label wellness, vertical integration helps reduce contaminants, eliminate middlemen, and provide accurate labeling. It’s also key to building trust—especially in formulations like FECO where full-spectrum integrity matters most.

Custom Dosing from the Start

Every new King Harvest client receives dosing guidance tailored to their goals, body, and condition. Starting with low doses and titrating up ensures minimal side effects and better outcomes. This method, refined since 2011, makes King Harvest a reliable partner for people navigating chronic pain, anxiety, and neurological disorders.

Case Study: Verano Holdings Shows Integration Wins

When Verano merged with AltMed in 2021, its vertically integrated model gained efficiency. A Leaf Trade study reported reduced manual errors and faster fulfillment rates—proof that seed-to-sale models not only improve traceability but scale operations sustainably.
