About — DevCannabis

The Problem

State cannabis regulators publish valuable data — patient counts, sales figures, licensee information — but in formats that are nearly impossible to use: PDFs, inconsistent spreadsheets, and dashboards that don't make export easy.

Comparative analysis is nearly impossible. Research is isolated and datasets drift, making it harder to quickly verify industry claims over time. Average consumers can't access the market intelligence as easily as large operators can.

Our Solution

DevCannabis extracts, standardizes, and publishes cannabis regulatory data as clean, accessible datasets. We archive original source documents for verification and provide multiple ways to access and audit the data:

Visual Dashboard

Interactive charts and tables for quick analysis without any coding required.

REST API

JSON access for approved developers, researchers, and contributors with signup/auth/API key.

CSV Export

Exports are available through approved access; bulk or commercial use requires written permission.

PDF Archive

Original source documents archived for verification and historical reference.

Source Notes

Citations, caveats, and correction paths so readers can challenge or verify a number.

Community Review

Source submissions and corrections go through review before they affect published data.

Who It's For

Enthusiast — Read public cannabis market data without needing a paid report or technical background.
Researchers — Access normalized data for academic studies on policy, economics, and public health.
Journalists — Verify industry claims with official data. Spot trends before they're news.
Advocates — Track program growth and compare policies across states.
Developers — Request API/source access to help add source-backed jurisdiction coverage.
Industry — Understand market dynamics without expensive consultant reports.

Our Principles

Transparency — All data comes from official public sources. We link to originals.
Open Methodology — Sources, assumptions, schemas, and corrections stay visible and reviewable.
Public access — Dashboards stay free; API/export access is controlled to protect reliability and fair use.
Accuracy First — We document our methodology and limitations. When we're not sure, we say so.

Current Coverage

6 live dashboards. Florida is the project's home market and one of the largest medical cannabis markets in the country, which is why it carries the deepest coverage and the longest source trail. Its source archive includes OMMU weekly report PDFs dating back to May 2016; the normalized dashboard history begins with the 2019 dispensing reports and expands as older source eras are validated. Colorado, Massachusetts, Michigan, Oregon, and Washington run as live spine dashboards sourced straight from each state regulator.

Built in the open

DevCannabis is a controlled-contribution public data project. We're looking for data contributors, approved developers, moderators/reviewers, and research partners who care about source-backed cannabis transparency.
