Our Data Sources

Where cannabis intelligence comes from — every source category we use, with notes on reliability and limitations.

Primary Sources

These are the most authoritative data sources available — direct from entities with legal authority to collect the data.

State Regulatory Agencies

Every state with a cannabis program publishes some combination of licensing data, tax revenue, sales figures, and enforcement actions. Quality and timeliness vary dramatically by state:

  • Best: Colorado (DOR monthly reports), Illinois (IDFPR/DOR monthly reports with in-state/out-of-state split), Washington (LCB monthly data)
  • Good: Oregon, Michigan, Nevada, Massachusetts, Arizona
  • Limited: California (aggregated, delayed), New York (limited reporting during rollout), Florida (quarterly)

Federal Agencies

  • DEA — scheduling status, enforcement data, rescheduling proceedings
  • FDA — Epidiolex approval data, adverse event reports, enforcement actions on CBD claims
  • IRS — 280E guidance, tax collection data
  • Census Bureau — population, demographics, economic data for market sizing
  • BLS — employment data, wage data, CPI

Public Company Filings

SEC filings (10-K, 10-Q, 8-K) and Canadian securities filings from publicly traded cannabis companies. These provide audited financial data including revenue, margins, store counts, geographic breakdowns, and management discussion of market conditions.

Key companies we track: Curaleaf, Green Thumb Industries, Trulieve, Verano, TerrAscend, Columbia Care, Cresco Labs, Tilray, Canopy Growth.

What We Do Not Use

  • Anonymous surveys with undisclosed methodology — cannabis industry press releases frequently cite surveys without disclosing sample size, methodology, or funding source
  • Generic market research report projections — broad national/global market reports with projections that often lack transparent methodology
  • Social media speculation — we monitor social signals for cultural trend detection but do not treat social media posts as data

Source Limitations

We are transparent about what cannabis data cannot tell you:

  • No state publishes cannabis business failure rates or survival statistics
  • Illicit market sizing is inherently estimated, not measured
  • Private company financials are not publicly available and must be estimated
  • Tourism economic impact data for cannabis is nearly nonexistent at the city level
  • Consumer preference surveys vary widely in methodology and are often industry-funded

Where we use estimated or modeled data rather than directly observed data, we say so.
